(Bus mastering device troubleshooting) ---------------------------------------------------------------------- 1) What are the PAS, PAS+, and the PAS-16? The PAS was the original PAS card. It is capable of FM synthesizing, and digital sound. It can do 8 bit digital sampling and 8 bit digital playback (I don't know at what rate). The PAS has shielding built into it that eliminates background noise that can be created by many of the components of computer systems (hard drives for example). The PAS+ is the new version of the old PAS. I don't believe the PAS is for sale anymore, as the PAS+ has probably replaced it. The PAS+ is capable of FM synthesizing, and digital sound. It has the shielding that the original PAS had. It can do 8 bit digital sampling and 16 bit digital playback. The PAS-16 is currently the most advanced sound card in the Pro Audio Spectrum line. It is capable of FM synthesizing, and digital sound. It can do 16 bit digital sampling and 16 bit digital playback. It has the shielding that was present in the original PAS. ---------------------------------------------------------------------- 2) What are the specs for the PAS-16? Here are the specs for the PAS-16. The specs for the PAS+ are identical, except that the PAS+ can only do 8 bit sampling, and requires you to specify when you want SB compatibility mode on or off. (Sorry, I don't have specs for the original PAS.) Compatible with the following sound standards: SoundBlaster (version 1.5--currently fine for any software) Adlib Thunderboard Pro Audio Spectrum MPC Windows with Multimedia Windows 3.1 True 16 bit stereo sound --16 bit stereo playback and recording (16 bit linear DAC) --Sampling/playback at 8, 12, and 16 bit PCM 4kHz-44kHz in stereo --Dynamic filtering 2Hz-22kHz programmable --ADPCM compression (2:1) and decompression (2:1, 3:1, 4:1) mono mode --Microphone, external line-in, and CD-audio inputs (enables you to make CD-quality 16-bit recordings from a variety of sources) --Shielded circuitry and dynamic filtering for low noise and clear sound Advanced 20 Voice Stereo Synthesizer --Yamaha YM262 (OPL-3) synthesizer --4 operator FM synthesized sound for true stereo --16 bit FM DAC --General MIDI compatible Audio Mixing --Internal synthesizer (stereo) --Digital audio (stereo) --CD audio (stereo) --External line-in (stereo) --Microphone --PC speaker --10 channels with stereo enhance Volume Control --Master volume: 0 to -62dB (1 dB/step) --Input mixer +1 to -60dB (2dB/step) Signal quality (1 V p-p reference) Dynamic range and signal to noise --Synthesized and mixed audio: 85 dB --Sampled audio PCM: 90 dB --Total harmonic distortion: 0.05% Frequency Response --30 Hz - 20 kHz (+- 3 dB) Audio Outputs --Drive level: 11.5 V (p-p) --Power: 4 watts per channel (software controllable volume, bass, and treble) --Load impedance: will drive 4 or 8 ohm speakers --Output connections: stereo mini jacks (1/8 inch) (same with line in) 16 bit PC Interface --16 bit DMA --Selectable IRQ (2-7, 10-15) --Selectable DMA (0-3, 5-7) --Software selectable DMA and IRQ settings with auto configuration MIDI Interface (Requires Optional MIDI Mate) --Full duplex MIDI port (can record and playback at the same time) IBM Standard Joystick Port High Performance SCSI Interface (Requires Optional SCSI Cable Kit) --Supports CD-ROM drives, SCSI hard drives, removable/erasable optical drives or removable cartridge drives --690 kB per second Connectors --Internal CD-Audio Connector at J5 is a 5-pin header connector, 0.100" space header, pin 1=ground, 2=right in, 3=ground, 4=left in, 5=ground. --The MIDI/Joystick Port is a D-15S connector type.

The original PAS is software compatible with the SB. You have to run a TSR to get the compatibility. I have heard that the compatibility is not very strong, since it is being done through software emulation. Both the PAS+, and the PAS-16 are hardware compatible with the SB. This means that there is basically a SB built into the board. It is like having two soundcards in one. You run the one PAS driver and voila, you have SB capability. By default, the SB section is set to IRQ 5, DMA 1, and I/O port 220h, while the PAS section is set to IRQ 7 and DMA 3. In addition, it is possible to use both the SB section and the PAS section at the same time. You could have game music going in the SB section, and then play a .wav file with the PAS at the same time. I have not run into any SB compatibility problems with my PAS-16. Adlib compatibility is included with the PAS+ and PAS-16. If you are running an older program that requires SOUND.COM to play Adlib sounds, you can use the included FM.COM instead. All SB games use DMA1, an IRQ and an I/O port. Some SB games look for the following statement in AUTOEXEC.BAT: "SET BLASTER=A220 I5 D1 T3", where A220 is for I/O port 220h, or which ever I/O port is selected at J10. Q5 is IRQ 5, or which ever IRQ is selected at J12. D1 is for DMA 1 which is required for SB compatibility. Try with T2 or T3 for timer. Other SB games do not look for this statement to find the settings but allow you to set the settings via an install program or by modifying a configuration file. A few games default to certain settings and do not allow the user to change these settings to match the board settings. Make sure that the game's settings match with the settings used by the SB section of the sound card. The default settings for the SB section are given above. Refer to the game's user guide or contact the game manufacturer for assistance. Some games do not work properly if the computer is running in TURBO mode. On most computers, there is a TURBO button on the front. If this button is not found, disabling the internal/external memory cache in the computer's CMOS setup achieves the same result. Here is a list of games whose SB and Adlib sounds work with the PAS+ or PAS-16: (NOTE: I generated this list through personal testing and from messages on the Usenet.) Adventures of Willy Bemish Commander Keen Continuum (Adlib) Conquests of the Longbow Duke Nukem Eye of the Beholder II F-15 Strike Eagle II (Adlib) F-117a Stealth Fighter Falcon 3.0 Galactix Gunship 2000 Hardball III Indiana Jones and the Last Crusade, Search for Atlantis Jill of the Jungle King's Quest V Leisure Suit Larry 5 Lemmings Links Monkey Island I & II Prince of Persia Railroad Tycoon Secret Weapons of the Luftwaffe Space Ace 2 Star Trek the 25th Anniversary Ultima VII Ultima Underworld Where in America's Past is Carmen Sandiego Wing Commander I & II Wolfenstein 3-D If you have seen any games working with the PAS+ or PAS-16 that are not on this list, please send the titles of these games to: thompson@ukanvax.cc.ukans.edu ---------------------------------------------------------------------- 4) How does the PAS-16 compare to the Soundblaster Pro? NOTE: Reports from the Usenet indicate that the Soundblaster Pro doesn't filter sound when it is sampling in stereo. It only filters in mono. Also, the card is not shielded very well from the radiation given off by your computer's components. If the hard disk is accessed when sampling, you can hear an audible pop in the sample. These problems do not appear with the PAS-16, which has shielding. Here is a summary of features and specs between the SB Pro and the PAS-16: SB Pro PAS-16 ------------------------------------------- Max sampling rate 44kHz 8 bit Mono 44kHz 16 bit (CD sound) in stereo Max playback rate 44kHz 8 bit Mono 44kHz 16 bit ( " ) in stereo Compatible with Adlib, SB, SB Pro Adlib, SB, PAS, PAS-16, Thunderboard Includes standard SCSI no yes Price $190 $215 ---------------------------------------------------------------------- 5) How does the PAS-16 compare with the Gravis Ultrasound? Here is a summary of features and specs between the Gravis Ultrasound and the PAS-16. NOTE: The Ultrasound is capable of 16 bit sampling and SCSI if you buy the appropriate daughterboards. The daughterboards should be available in the 4th quarter of 1992. These boards will have to be purchased separately and then plugged into the main Ultrasound board for it to gain 16 bit sampling and SCSI capability. Ultrasound PAS-16 ----------------------------------------- Max sampling rate 44kHz 8 bit 44kHz 16 bit (CD sound) in stereo in stereo Max playback rate 44kHz 16 bit (CD sound) 44kHz 16 bit (CD sound) in stereo in stereo Compatible with Adlib, SB, Ultrasound Adlib, SB, PAS, PAS-16, Thunderboard Includes standard SCSI no yes Price as is $130-160 $215 Price w/ 16 bit sampling $180-240 $215 Price w/ SCSI $180-240 $215 Price w/ 16 bit & SCSI $230-320 $215 Prices for the Ultrasound assume a $130-160 range for the card itself, and a $50-80 range for the 16 bit daughterboard and $50-80 for the SCSI daughterboard. ---------------------------------------------------------------------- 6) Will I have problems using a PAS card with a fast computer (486)? I have used a PAS-16 for five months with no problems on a 486-33 ISA machine. ---------------------------------------------------------------------- 7) Will OS/2 drivers be available for the PAS cards? Word from the Usenet is that OS/2 drivers are being written right now. They should be out in late October or early November. Even if you don't have OS/2 drivers, the PAS cards will work fine in a virtual DOS session, or in Win-OS/2. Just be sure to put the mvsound driver into the DOS_DEVICE window in the DOS settings. You can also use the Windows Multimedia extensions with Win-OS/2 and the PAS cards. When Windows 3.1 support is available in OS/2 (probably in November), then you can use the Windows 3.1 drivers in OS/2. ---------------------------------------------------------------------- 8) What software comes with the PAS-16? The PAS-16 comes with a variety of software. Make sure that you get version 1.2 or above. If you have an earlier version, contact Media Vision for an upgrade. The PAS+ comes with the same software. Both 3.5 inch and 5.25 disks are included. Here is a summary: Stereo Studio F/X -- PC Waveform Sound Editor --Record, playback, edit, cut & paste stereo sound files --Uses standard MPC files (.wav) --Imports .voc, and .bin files --Records sounds from a microphone, CD, or any sound source --Effects include echo, reverb, and envelope shaping Control Panel -- Software controlled mixer --Control CD-audio, digital audio, FM synthesized audio, external line-in, microphone, and PC speaker --Includes controls for bass, treble, loudness, and stereo enhance --Includes both DOS and Windows versions TrakBlaster Pro -- Four track music studio --Combines 44kHz stereo with VGA graphics --Includes 4 track scope, spectrum analyzer, and left and right VU meters SP Spectrum -- MIDI Sequencer --Compose and playback music using the on board 20 voice stereo synthesizer or other MIDI devices Monologue -- Text to speech synthesizer --Version 3.0 for DOS --Lets your computer talk to you --Will 'read' text files Music and Sound Effects Library --Includes a selection of MIDI songs, digital sound effects, and MOD files Audio Mate -- DOS based multimedia application --Add CD-audio, digital sound effects and stereo synthesized audio to your existing DOS files --Works with Autodesk Animator, Animator Pro, Harvard Graphics, and others --Add sound to .bat and .exe files DOS Drivers Windows Drivers --Includes drivers and DLL's for Windows 3.1 and Windows with Multimedia ---------------------------------------------------------------------- 9) Is setting up a PAS+ or PAS-16 hard? Not at all. You put the DOS install disk in your floppy drive, set the current drive the floppy, and type INSTALL. You can then set the IRQ's and DMA channels from the software--no flipping dip switches or resetting jumpers. To install the Windows software, just put the Windows install disk in the floppy, and run INSTALL from Windows. The appropriate line to start the PAS driver is inserted in your config.sys (only after receiving confirmation from you). You're done. ---------------------------------------------------------------------- 10) I have installed my PAS+ or PAS-16, but the sound from games is very low and hard to hear. What's wrong? I had the same problem. You need to set the mixer on your card so that the volume is a little higher. You can also set the bass, treble, loudness, stereo separation, and a few other things. To turn the volume up, you use the PAS.EXE program in your PROAUDIO directory. Refer to the manual on how to use PAS.EXE. When you get everything set up right, put it in a batch file to be run from your autoexec.bat. That way, the mixer is set up when you turn on your computer. ---------------------------------------------------------------------- 11) Is there a development kit available for the PAS cards? Media Vision has a developer's kit that is free of charge. It will work with the PAS/PAS+/PAS 16 cards. ---------------------------------------------------------------------- 12) How can Media Vision, the maker of the PAS cards, be reached? Contact Media Vision Technical Support for technical assistance on: Stereo Studio F/X, SP Spectrum, Software Controlled Mixer (PAS.EXE), TrakBlaster Pro, Monologue v3.0 for DOS, Music and Sound Effects Library, AudioMate, Windows Drivers and Pocket Tools.

Upgrade information: (800) 283-1596 extension 100 ---------------------------------------------------------------------- 13) How good is the quality of various sampling rates? To get an idea of how good the quality of various sampling rates is, here is a chart comparing sampling rates to everyday sounds: Sampling Rate Similar in quality to 44.1 kHz CD 32 kHz Cassette 22 kHz FM radio 11 kHz AM radio 6 khz Phone voice ---------------------------------------------------------------------- 14) How much memory does the PAS-16's MVSOUND driver take up? The MVSOUND driver is what the PAS-16 uses to talk to your computer's hardware. You load this driver from your config.sys, and it gives you PAS-16 compatibility, SB compatibility, and Adlib compatibility. The driver takes up about 9.2 kb of RAM. It can be loaded high. ---------------------------------------------------------------------- 15) Where can I purchase a PAS-16 or PAS+ card? The cheapest place to get these cards is from a mail order house. Many dozens of mail order houses can be found in Computer Shopper. One such house that sells the PAS-16 and PAS+ is Computability. There phone numbers are: Toll free: 1-800-558-0003 Regular: 1-414-357-8181 (in case you don't live in the U.S. and can't dial an 800 number) Hours: 9:00am - 9:00pm Monday - Friday (Central Standard Time) 11:00am - 5:00pm Saturdays The last price I heard that Computability was selling the PAS-16 for was $215. NOTE: I am not affiliated with Computability. ---------------------------------------------------------------------- 16) What is the Media Vision Pro-16 Multimedia System package and what does it contain? The Media Vision Pro-16 Multimedia System package is a complete Multimedia upgrade kit that Media Vision sells. It contains all the hardware you need to get you ready for multimedia. It is compatible with the MPC standard. The CD-ROM that is included with it is one of the fastest (in access time and throughput) on the market. The package includes: Pro Audio Spectrum 16 Sound Card NEC CDR-83J CD-ROM Drive (an OEM version of CDR-83) with drive rails and screws SCSI/Cable Driver Kit (The CD-ROM drivers are included in the Installation Disk 1) One CD-ROM Caddy Sierra King's Quest on CD-ROM Macromind Action on CD-ROM & Manual Introduction to Nautilus on CD-ROM Lotus 1-2-3 For Windows With Multimedia Help on CD-ROM (Shipped by Marketing upon receiving the Product Registration Card from the customer.) ---------------------------------------------------------------------- 17) What SCSI CD-ROM drives are supported by the PAS-16 and PAS+? Internal Drives: Chinon CDS-431. Contact Chinon at 310-533-0274 to get the 40-pin to 50-pin converter. Hitachi CDR-3650 NEC CDR-80, CDR-82, CDR-83, CDR-83J, CDR-83M, CDR-84 Sony CDU-541 Texel DM-3020, DM-3021 Toshiba XM-3201B External Drives: Chinon CD-SC (Sony CDU-8001), CD-SC Plus (Sony CDU-8002), CDX-431 CD Technologies Porta-Drive Denon DRD-253 Hitachi CDR-1553S, CDR-1650, CDR-1750S IBM 3510 Laser Magnetics CM212, CM214, CM231 NEC CDR-35, CDR-36, CDR-36M, CDR-72, CDR-73, CDR-73M, CDR-74, CDR-77 Panasonic CR-501-S Pioneer DRM-600 6-disc changer Sony CDU-6211, CDU-7211 Texel DM3010, DM-3120, DM-5020, DM-5021, DM-5120, DM-7120A, DM-7120B Toshiba XM-3201A, XM-3301, XM-5100A If your CD-ROM drive is not on this list, it will NOT work with the PAS-16 (the SONY CDU-535 and the Laser Library are not SCSI). If it is on this list and you would like to use the PAS-16's SCSI interface to control the CD-ROM drive, then contact Media Vision. ---------------------------------------------------------------------- 18) I can't get my PAS-16 to work. What's wrong? (Standard Troubleshooting) Generic CONFIG.SYS: DEVICE = C:\WINDOWS\HIMEM.SYS FILES = 30 BUFFERS = 10 LASTDRIVE=X (For CD-ROM drive. Refer to the SCSI INTERFACE section below.) DEVICE = C:\PROAUDIO\MVSOUND.SYS D:X Q:X V:X J:X T:X (Refer to the PAS-16 SOFTWARE INSTALLATION section below.) DEVICE = C:\WINDOWS\SMARTDRV.EXE 2048 512 DEVICE=C:\PROAUDIO\TSLCDR.SYS /D:MVCD001 /R /P:3 (SCSI CD-ROM driver. Refer to the SCSI INTERFACE section below.) Generic AUTOEXEC.BAT: @ECHO OFF PATH = C:\;C:\DOS;C:\WINDOWS;C:\PROAUDIO PROMPT $P$G C:\PROAUDIO\MSCDEX.EXE /D:MVCD001 /M:10 /L:X /V (CD-ROM driver. X is the drive letter assigned to the CD-ROM drive. Refer to the SCSI INTERFACE section below) 1. Reduce to the generic CONFIG.SYS and AUTOEXEC.BAT. 2. Reduce the computer's CPU speed. Usually this can be accomplished by turning off the TURBO mode or disabling the internal/external memory cache by going into the computer's CMOS setup. 3. Reduce the computer's bus speed to 8MHz. The PAS-16 was designed around the IBM AT specification which uses this bus speed. Please note that this is not the same as the CPU speed. Once everything works fine at the 8MHz bus speed, you can experiment with higher bus speeds. 4. Remove other peripheral boards from the computer, such as scanner boards, tape backup boards, ... 5. Try the PAS-16 in another 16-bit slot. 6. Try the PAS-16 in another computer. 7. If you do not hear any sound, recheck the speaker/headphone connections. ---------------------------------------------------------------------- 19) I have some questions about hardware installation. (Hardware installation troubleshooting) --Do I have to change any jumpers before I install the PAS-16? The default settings will work in most computers. Only try with different IRQ (at jumper J12) and I/O port (at J10) settings if you experience any problems or know that these settings are used by another peripheral board in the same system. --How do I change the DMA and IRQ settings for the PAS-16 section of the sound card? The PAS-16's DMA and IRQ can be changed by changing the D:x and Q:x parameter on the MVSOUND.SYS statement in the CONFIG.SYS file. --How do I change the IRQ and I/O port settings for the SB section of the sound card? The SB's IRQ and I/O port can be changed by changing the jumpers at J12 and J10 on the sound card. --Can the PAS-16 section and the SB section share the same settings? No. The settings must be different to prevent a DMA and IRQ conflict. --What are the symptoms of a DMA and IRQ conflict on the PAS-16 section? DMA conflict causes digital audio to be distorted or no digital audio. It can also cause system to hang, reboot, or issue parity error. IRQ conflict causes digital audio to loop and no synthesized audio. --What are the symptoms of an IRQ and I/O port conflict on the SB section? The game does not produce digital audio or digital audio is distorted, or, running the game causes the computer to lock up. --What causes a Memory Parity Error? A DMA conflict. --Which jumpers on the sound card can I change? The only ones that can be changed are the SB jumpers: J10 for I/O port, J11 for DMA 1, and J12 for I/O port. --How do I disable SB compatibility mode? Float all of the shunts for J10, J11 and J12 (by putting the shunt on 1 pin only). This will disable the SB's IRQ, I/O port and DMA 1. --Does the PAS-16 work in a 486/50, or, What computers does the PAS-16 work in? The PAS-16 was designed around the IBM AT specification. It will work in a 486/50 if the bus (I/O CLK) speed is lowered down to 8MHz. Please note that this is not the same as the CPU speed. Once it works fine at 8MHz bus speed, you can experiment at higher speeds. ---------------------------------------------------------------------- 20) I have some questions about the installation program. (Software installation troubleshooting) --What drivers can be loaded high? If there is sufficient upper memory available, you can load MVSOUND.SYS, TSLCDR.SYS and MSCDEX.EXE high. --I have just received a new version of the PAS-16 Installation Disks. Can I install it over the old version? It is best to remove the PROAUDIO directory including all sub-directories first before you install the new version. --Why does the INSTALL program only allow DMA 1 or 3 to be selected? Most existing DOS applications only support DMA 1 and 3. You can use a text editor such as MS DOS 5.0's EDIT to change the D:x parameter on the MVSOUND.SYS statement in CONFIG.SYS. --The INSTALL program causes my computer to lock up, or, how do I manually install the software? To manually install the PAS-16 software on Installation Disks 1 & 2, do as follows: Add the "C:\PROAUDIO" to the path statement in AUTOEXEC.BAT. Reboot the computer. MD C:\PROAUDIO MD C:\PROAUDIO\MIDI MD C:\PROAUDIO\WAVE MD C:\PROAUDIO\STEREOFX MD C:\PROAUDIO\TBPRO Copy LHARC.EXE from the PAS-16 Installation Disk 1 to C:\PROAUDIO. Copy DIGISNDW.LZH to C:\PROAUDIO\WAVE. Copy MIDI.LZH to C:\PROAUDIO\MIDI. Copy MOD.LZH to C:\PROAUDIO\TBPRO. Copy PROGRAMS.LZH to C:\PROAUDIO. Copy PAS-16.SYS to C:\PROAUDIO. Copy CHORD.WAV to C:\PROAUDIO. Rename PAS-16.SYS to MVSOUND.SYS. Copy SFX.LZH from the PAS-16 Installation Disk 2 to C:\PROAUDIO\STEREOFX. From the C:\PROAUDIO directory, type LHARC X PROGRAMS.LZH From the C:\PROAUDIO\WAVE, type LHARC X DIGISNDW.LZH From the C:\PROAUDIO\MIDI, type LHARC X MIDI.LZH From the C:\PROAUDIO\TBPRO, type LHARC X MOD.LZH From the C:\PROAUDIO\STEREOFX, type LHARC X SFX.LZH Add the following line to CONFIG.SYS DEVICE=C:\PROAUDIO\MVSOUND.SYS D:3 Q:7 Reboot the computer. --What is MVSOUND.SYS for? It enables the PAS-16 to produce sound under DOS and is also required for WIN31 drivers. --After I installed the PAS-16 Installation Disks and reboot the computer, right after MVSOUND.SYS finishes loading, I hear crackling/scratchy noises coming out of the speakers. Make sure your Installation Disks have the current version of 1.2. Add "T:1" to the end of the MVSOUND.SYS statement. Save CONFIG.SYS and try again. Refer to page 1-25 of the PAS-16 User's Guide v1.1 for an explanation. --What parameters does MVSOUND.SYS support? D:x, x is (0,1,2,3,5,6,7) for DMA for the PAS-16 section of the card. Q:x, x is (2-7,10-15) for IRQ for the PAS-16 section of the card. J:x, x is 0 or 1, 1 is for Joystick Enabled (default), 0 is for Joystick Disabled. V:x, x is from 1 to 100, which is the initial volume setting. T:x, x is 0 or 1, 1 is to use the on-board oscillator, 0 is to use the motherboard's oscillator. Some computers such as 486/33 OPTI have improperly-designed oscillator which causes the OPL3 FM chip on the PAS-16 to produce random noises. See Page 1-25 of the PAS-16 User's Guide v1.1 for an explanation. Note: Not all software support high-order DMA and IRQ (for example, TrakBlaster Pro). ---------------------------------------------------------------------- 21) I have some questions about the SCSI interface on my PAS-16. (SCSI interface troubleshooting) --What is TSLCDR.SYS? This is a CD-ROM driver written by Trantor Systems. It comes with the SCSI/Cable Driver Kit. The current version is 1.46B. The parameters that are supported are: D:x, x is any device name that you assign to the CD-ROM device. R is for reset. --What is MSCDEX.EXE? This is the Microsoft CD-ROM Extensions. The current version is 2.21. The parameters that are supported are: D:x, x is the same device name that is assigned to the CD-ROM device by TSLCDR.SYS. M:x, x is the number of 2K memory buffers, 10 is usually used. L:x, x is the drive letter you want to assign to the CD-ROM drive. V is for a verbose listing of information about memory usage. E is for expanded memory usage. --I don't need the SCSI or audio cable. Can I just get a copy of TSLCDR.SYS and MSCDEX.EXE? These drivers are royalty-bearing software which means they cannot be provided free of charge. Also, they come with the SCSI/Cable Driver Kit only. --Which CD-ROM drives can I use with the PAS-16? See the SUPPORTED CD-ROM DRIVES section above. The PAS-16 has a SCSI interface which allows it to control SCSI devices. Please contact Media Vision Sales for the SCSI CD-ROM Cable/Driver Kit (Specify internal or external). --Do I have to use the PAS-16's SCSI interface to control my CD-ROM drive which has its own controller? No. All that you have to do is to make sure that the CD-Audio signals are routed from the CD-ROM drive to the PAS-16. --I already have a SCSI adapter in my system. Will I have to remove it if I install the PAS-16? Can multiple SCSI adapters co-reside in my PC? You can have as many SCSI adapters in the same system as there are available slots. The PAS-16's SCSI will not interfere with other SCSI adapters. The only possible conflicts would be conflicts with DMAs, IRQs and I/O port used by the sound card. --I have the Sony CDU-535 CD-ROM drive (or Laser Library). Can I use the PAS-16 to control the Sony drive? No. This Sony drive uses a proprietary Sony Bus interface. Media Vision will release the PAS-16 and PAS+ Sony Bus version in the near future to work with this drive. Contact Customer Service. --Can I use the PAS-16 to control other SCSI devices? Yes. Trantor Systems can be reached at 510-770-1400 for a $59.00 driver set which supports all SCSI hard drives, removable hard drives and magneto-optical drives. Currently there is no driver support for tape drives or scanners. --I used to have the original PAS board and a SCSI/Cable Driver Kit and have just updated to the PAS-16. Do I need an updated version of the CD-ROM drivers? Contact Customer Service for a free driver update for both TSLCDR.SYS and MSCDEX.EXE. --I have the ATI Graphics Ultra (or Vantage) and when the TSLCDR.SYS driver loads it detects two SCSI addresses. I also experience problems with digital audio and get a red screen on WIN31. Make sure you have TSLCDR.SYS v1.46B or later. --Which SCSI Interface is used on the PAS-16? How do I write device drivers for it? The PAS-16 uses the Zilog's Z5380. Contact Media Vision Customer Service for documentation on the chip's specification and the PAS-16 Software Developer's Toolkit. This software toolkit is currently under development. --What is the transfer rate of the PAS-16's SCSI interface? It has a maximum transfer rate of 690KB/sec. --I get the error "No SCSI host adapter found". First, the SCSI CD-ROM driver is board dependent. If you would like to use the PAS-16 to control the CD-ROM drive, you need to use our TSLCDR.SYS driver v1.46B or later; otherwise, if you would like to use another SCSI controller (such as Adaptec or F --I get the error "No devices respond on this SCSI host adapter". First, make sure one of the computer's power cables has been connected to the back of the CD-ROM drive. Second, check the internal flat ribbon SCSI cable to make sure it is properly connected to the back of the CD-ROM drive. --I get the error "Device driver not found: MVCD001. No valid CD-ROM selected". First, if you are using DR DOS 6.0, it is necessary to change the device name for both TSLCDR.SYS and MSCDEX.EXE statements from "MVCD001" to "TSLCD". Second, make sure that the device name in both of these statements match. --I get the error "Incorrect DOS version". If you are using MS DOS 5.0, MSCDEX.EXE v2.2 requires that CONFIG.SYS has the statement "DEVICE=C:\DOS\SETVER.EXE". You should not get this error f you have MSCDEX.EXE v2.21. This driver comes with our SCSI/Cable Driver Kit or can be downloaded from --I get the error "Invalid drive specification" when I type the drive letter assigned to the CD-ROM drive. First, make sure that you have "LASTDRIVE=X" in the CONFIG.SYS file, where X is the next logical drive letter after the letter assigned to the CD-ROM drive in the MSCDEX.EXE statement. Second, make sure that the TSLCDR.SYS driver statement precedes a --I get the error "CDR 101: Drive not ready". First, make sure that you are not trying to read a CD-Audio disk. Second, check in the internal, flat ribbon SCSI cable to make sure it is properly connected. Third, move the TSLCDR.SYS and MSCDEX.EXE statements to the end of CONFIG.SYS and AUTOEXEC --I get the error "CDR 103: CD-ROM not High Sierra or ISO-9660 format reading drive X. Abort, Retry or Ignore?" First, check to make sure that you are not trying to read a CD-Audio disk. Second, this is usually caused by a software conflict. Reduce to the generic CONFIG.SYS and AUTOEXEC.BAT and try again. --I do not hear any CD-Audio at all, or, How do I connect the internal CD-Audio cable? The internal CD-Audio cable may not have been properly connected or it is defective. Use a custom audio cable to connect the PAS-16's internal audio input at J5 to the CD-ROM drive. --Does the PAS-16 support CD-ROM XA? No. This feature may be supported in the future. ---------------------------------------------------------------------- 22) I have some questions about Stereo Studio FX. (Stereo Studio FX troubleshooting) --Does SFX support 16-bit PCM recording and playback? SFX only supports 8 bits. --Sound loops when playing back under SFX. DMA 3 and IRQ 7 are set in CONFIG.SYS file. All other applications work fine. First, make sure that the file is not a 16-bit recorded file. SFX only supports 8-bit recorded files. Second, try using a high-order DMA, such as DMA 5. --Activating "Record" in SFX disconnects the channels. This problem has been reported to Media Vision. ---------------------------------------------------------------------- 23) I have some questions about SP Spectrum. (SP Spectrum troubleshooting) --TAPIMV issues the error "FM sound card not found." Make sure your Installation Disks have the current version of 1.2. Add "T:1" to the end of the MVSOUND.SYS statement. Refer to page 1-25 of the PAS-16 User's Guide v1.1 for an explanation. --I have the Media Vision MIDI Mate v1.0 (MIDI connector box) which worked fine on the PAS. After I upgraded to the PAS-16, MIDI IN does not work using the same MIDI Mate. Inside MIDI Mate, there is a chip at U1 (next to the MIDI cable) called an opto-isolator. The old part number is 6N136. For the MIDI Mate to work with the PAS-16, it needs the new part number which is 6N138. Contact Customer Service for an RMA number. --The FMEDIT section in the PAS 16 User's Guide has missing pages to describe the Mixer, Display Setup, Trigger Note, Quitting, and Pop-up Windows. Please contact Customer Service for a copy of this sent by mail. --I don't hear any sound when I play a .ROL or .MID in SP Spectrum. Make sure that Port is set to 2 for playing songs using the internal FM synthesizer. Set Port to 1 for playing out of an external MIDI equipment. Refer to the SP Spectrum section in the PAS-16 User's Guide for additional information. --I get the error "Run time error. Divide by 0" when I run SP Spectrum. This is caused by an incorrect setup of the memory manager, commonly seen in QEMM and Wytek co-processor in 486 machines. Contact Quarterdeck or the manufacturer of the memory manager for assistance with reconfiguration. ---------------------------------------------------------------------- 24) I have some questions about TrakBlaster Pro. (TrakBlaster Pro troubleshooting) --While running TBPRO, a MOD file plays for 20 seconds then abruptly stops and system hangs up. This is caused by a DMA conflict. Make sure the PAS-16 section is not set for DMA 1 unless the SB compatibility has been disabled. --Does TBPRO support high-order DMA and IRQ? No. TBPRO only supports DMA 1,3 and IRQ 2,3,5,7. ---------------------------------------------------------------------- 25) I have some questions about Monologue. (Monologue troubleshooting) --Running Monologue causes my computer to lock up. Monologue uses the SB section of the sound card. Monologue defaults to IRQ 7 where as the SB section of the sound card (at J12) defaults to IRQ 5. To change Monologue's IRQ setting to match the card's setting, run Monologue's INSTALL. --All possible SB's IRQs at J12 have been tried and Monologue still locks up or does not produce any audio. Select the "AdLib" driver instead of "Media Vision Products" and try again. Also, you need to run you bus at its standard speed (8 mHz). If you run it faster, Monologue will lock up. Try resetting the bus speed back to 8 mHz using your BIOS setup. --Dr. DOS 6.0's memory manager causes Monologue to lock up the computer when using ALT-T to activate Monologue. First, run MEMMAX -U to disable upper memory. Second, run Monologue. Third, run MEMMAX +U to re-enable upper memory. --The TALKDRVR.SYS is missing from the Monologue v3.0 For DOS disk. This driver was provided with Monologue v2.0 and has been removed from the disk for v3.0 by the software manufacturer (First Byte). --The Monologue User's Guide indicates that there should be two 5 1/4" disks. There is only one 5 1/4" disk. --The "Alt-T" key combination does not work. Some programs like WordPerfect or WordStar also use the same key combination which will create a conflict with Monologue. To resolve this problem, you need to assign a new hot key combination. Go into the Monologue directory and run CONFIG.BAT. --Monologue's "Alt-T" key combination does not work properly. Sometimes it does and sometimes strange things happen. First, delete the Monologue directory completely. Re-install Monologue and then try again. --When I run "SAYFILE filename.doc" at the DOS prompt nothing happens. SAYFILE.BAT is missing a parameter to allow a DOC filename to be passed to the SAYF.EXE so that it can speak the file. Modify SAYFILE.BAT by changing the third line from "SAYF" to "SAYF %1" and then try again. Run "SAYFILE filename.doc". Press Enter. ---------------------------------------------------------------------- 26) I have some questions about AudioMate. (AudioMate troubleshooting) --I am having trouble running Animator Pro with Audiomate. TAPIMV2 needs to be updated to support Animator Pro. Please contact Customer Service if you would like to be added to a waiting list for the update. ---------------------------------------------------------------------- 27) I have some questions about the Windows drivers and Pocket Tools. (Windows drivers and Pocket Tools troubleshooting) --What do I need to do before I install the PAS-16 Windows Drivers disk? If you have the PAS Windows drivers installed or have an older version of PAS-16 drivers, go into the Control Panel, Drivers, and remove every driver which references Pro Audio Spectrum or Media Vision. Restart WIN31 and then install the new drivers. Or, if you have Norton Desktop For Windows which will interfere with our Windows Driver's INSTALL program. To work around the problem, go into SYSTEM.INI, [boot] section. Replace "SHELL=NDW.EXE" with "SHELL=PROGMAN.EXE". Or, if you are using DR DOS 6.0's SHARE which causes our INSTALL program to crash the system. To work around the problem, remove SHARE. Re-boot the computer. Then install the Windows drivers. --Do I need MVSOUND.SYS for Windows? Currently, yes. In the future, the PAS-16's Windows drivers will not have to depend on MVSOUND.SYS. --Can I use different IRQ and DMA settings under Windows, than under DOS? The DMA set in SYSTEM.INI for Windows can be different from the DMA set in CONFIG.SYS for DOS as long as WIN31 is started in 386-Enhanced mode. However , if you start WIN31 is started in standard mode, you make make the settings the same. --What is the advantage of using a high-order DMA and IRQ? High-order DMA allows 16-bit DMA transfer which enables the MVPROAUD.DRV sound driver to handle digital audio more efficiently and also to provide more available DMA selections. High-order IRQ only provides more available IRQ selections. --I have just received the latest version of the PAS-16 Windows Drivers disk. Do I have to remove the older version first? Yes. --Sound plays normally under DOS using the selected DMA and IRQ settings, but loops under Windows using the same DMA and IRQ settings. This is caused by an IRQ conflict. Edit the SYSTEM.INI file to change the IRQ setting under [mvproaud.drv] section. --Pro Mixer's wave meter points at the beginning of the red area instead of at zero. A future release of WIN31 drivers will correct this problem. It is currently in beta. --What do I have to do before I can record using Pocket Recorder or Sound Recorder? Go into Pro Mixer or Pocket Mixer to set the audio input source to recording mode. --When I record at 16-bit mode, there is very bad clipping or it does not work at all. 8-bit recording works fine. If you are using an low-order DMA then change to a 16-bit DMA under the [mvproaud.drv] section of SYSTEM.INI and try again. --Recording at 8-bit is very scratchy. 16-bit recording does not have this problem. The PAS-16 has a 16-bit PCM DAC. Recording at 8-bit using a 16-bit DAC is definitely more noisy than recording at 8-bit on the PAS which only has an 8-bit DAC. In the next release, Pocket recorder will record better at 8 bits. --Does the Pocket Recorder support the Cut, Copy and Paste features? These features will be supported in the next release. This release is currently in beta. --I get the errors "Can't find input device with pid." and "Can't find output device with pid." when trying to run Pocket Recorder. Make sure the MVSOUND.SYS statement appears in CONFIG.SYS and that the driver loads properly when the computer boots up. --If Pocket Recorder is used to record a 16-bit wav file, and is saved then played from Media Player, the file will play properly to the end but the thumb button on the position slider will not have reached the end. This problem has been reported to Media Vision and will be fixed in the future release of WIN31 Drivers v1.4. --While recording under Pocket Recorder, if I open/close/use other applications, there are clicking/popping sounds that also get recorded. This problem has been reported to Media Vision and is currently being researched. --Pocket Recorder's OLE (Object Linking & Embedding) does not work properly. The OLE feature is not fully implemented. Please document the problems in detail and fax or mail to Technical Support to be forwarded to Media Vision. --A file recorded using RECFILE.EXE (PAS-16's DOS utility) plays back fine under Pocket Recorder but this same file will not play back under Media Player. And under Sound Recorder, loading this file will cause the "General Protection Fault Error In S A new version of RECFILE.EXE, dated 6-22-92 or later, does not have this problem. On BBS, download P16REC.ZIP; on Compuserve, download TOOLS.ZIP. --How do I play CD-Audio under WIN31? First, put a CD-Audio disk into the CD-ROM drive. Failure to do this will cause the [MCI] CD-Audio driver to not install properly Second, go into the Control Panel, Drivers. Click on the Add button. Select "[MCI] CD-Audio" driver. Click on the OK --I do not get any FM sound when I run DOS games under the DOS shell of Windows. The OPL3 FM synthesizer chip on the PAS-16 can operate in either OPL3 (4-operator) mode or 3812 (2-operator) mode. Under Windows, Voyetra's OPL3.DRV driver puts this FM chip into the OPL3 mode to produce rich FM sounds. However, most existing games only use the 2-operator mode. This should change in the future. --Under Media Player, CANYON.MID plays properly but when I play other MIDI files, I don't hear any music. WIN31 only supports General MIDI. The MIDI files that you have may be Non-General MIDI. ---------------------------------------------------------------------- 28) I have some questions about RECFILE and PLAYFILE. (RECFILE and PLAYFILE troubleshooting) --How do I use the command parameters Vxxx, V+xxx and Fx for RECFILE.EXE? Vxxx, where xxx is a number from 000-127 for voice-activated level. Only sounds at and above this level get recorded. V+xxx, where xxx is 000-127. Record all when voice is activated at threshold. Fx, where x is between 0-6 and selected using the following guidelines: Filter Value Limiting Frequency Sampling Rate Frequency Range 6 18 KHz 44 KHz near CD 5 16 KHz 32 KHz cassette 4 12 KHz 24 KHz FM radio 3 9 KHz 18 KHz AM radio 2 6 KHz 12 KHz telephone 1 3 KHz 6 KHz male voice 0 0 KHz mute --When PLAYFILE.EXE starts and stops, it produces a "popping" sound. Get a newer version of PLAYFILE.EXE. Please download P16REC.ZIP from the BBS. --I am having trouble recording 16-bit wave files using the V+xxx parameter. Get a newer version of RECFILE.EXE. Please download P16REC.ZIP from the BBS. --I do not hear any sound when I play back under WIN31's Media Player a file which has been recorded using RECFILE.EXE. Get a newer version of RECFILE.EXE. Please download P16REC.ZIP from the BBS. --I get the error "File is full or blocked" when I run RECFILE.EXE. This problem is caused by slow system throughput. First, reduce to a generic CONFIG.SYS and AUTOEXEC.BAT. Second, make sure the hard disk has been optimized (unfragmented). Third, try at a lower sampling rate or try recording to a ramdrive. ---------------------------------------------------------------------- 29) I have problems hearing sounds with certain games. (Games compatibility troubleshooting) --The joystick does not work at all or does not work properly when using the PAS-16's joystick port. First, some computers have a built-in joystick port on the motherboard. Other computers have a multi-I/O board that has a joystick port. Make sure that only one joystick port is enabled and the other one is disabled. Second, if the computer is to --I have games that have already been installed before I installed the PAS-16. These games are still playing through the internal PC Speaker. You need to re-select the sound card or re-install each game. Please refer to the guides for these games or contact the game manufactures for assistance. -Links, The Golf Game, by Access, causes my computer to lock up. Links defaults to IRQ 3 and I/O 220. And the PAS-16 defaults to IRQ5 and I/O 220. Run SETBLAST.EXE (which came with Links) to change the defaults used by Links to match whichever settings used by the PAS-16. --Wing Commander II, by Origin, causes my computer to lock up or does not produce any digital audio. First, make sure you have enabled speech in the WC II's INSTALL.EXE program. Second, make sure you have expanded memory. Third, if you use QEMM 6.0, the "Stealth" option may distort sounds and lock up the computer. Fourth, check the WC II's WC2.C --Falcon 3.0, by Spectrum Holobyte, does not play any radio voice messages and produces popping sounds. Try running the computer in non-TURBO mode or by disabling the internal/ external memory cache. If the problem persists, contact Spectrum Holobyte at (510) 522-1164 to request a software patch.

LHX, by Electronic Arts, only plays sounds out of the internal pc Speaker or b. Ultima V1, by Origin, produces distorted/noisy sound effects and music. Please slow down the computer and try again. This game does not abide by the sound requirements of the FM synthesizer chip, creating a problem when running in fast machines. --Robin Hood, The Legend of the Long Bow, by Sierra, produces poor or no digital audio. If the PAS-16 is currently set at IRQ7, please select a different IRQ, for example IRQ5, and then try again. --Ultima Underworld does not produce any digital audio. Music plays fine. After you have finished installing the game and selected the Sound Blaster driver. Run UWSOUND, which comes with Ultima Underworld, to select the IRQ setting to match with the PAS-16's IRQ setting. --I am having trouble running Interplay's Star Trek: The 25th Anniversary. Can't select the Pro Audio Spectrum from the sound options. The Pro Audio Spectrum option is for the PAS. The PAS uses a 2-operator FM synthesizer chip, and the PAS-16 uses a 4-operator FM synthesizer. The AdLib or SB sound options should work fine. --After exiting Windows 3.1 and running Sierra's Mixed-Up Mother Goose, FM sounds are faint. Cranking up volume helps but exposes background noise. The PAS-16's VPASD.386 driver will be updated to resolve this problem. --I am having trouble running Microprose's Gunship 2000. Microprose has developed new sound drivers which can be downloaded from our BBS. The file name is GUNSHIP.ZIP which contains different driver files for different IRQ settings. During GS2000's setup routine, select the AdLib driver. --I am having trouble running Kings Quest V on CD. Music plays fine but there is no speech. First, try "PAS RESET". Second, make sure that the SB driver has been selected. Third, make sure that the CD-ROM drivers have been properly loaded and that the CD-ROM drive is responding since KQ5 needs to access the CD-ROM drive to play speech. --I am having trouble running Microprose's F-117. Sounds play at the wrong speed. This game plays FM synthesized audio. Make sure your Installation Disks have the current version of 1.2. Add "T:1" to the end of the MVSOUND.SYS statement. Refer to page 1-25 of the PAS-16 User's Guide v1.1 for an explanation. ---------------------------------------------------------------------- 30) I have some questions about bus mastering devices. (Bus mastering device troubleshooting) --I hear periodic clicking sound or static noise whenever the hard disk's light goes on (while drive is being accessed). Lower the bus on-time and increase the bus off-time by the same amount so that the on-time is smaller than the off-time, or experiment to find the best ratio. For example, with the Adaptec 1542B SCSI Hard Disk Controller, the config.sys lines look like this: DEVICE=C:\ASPI4DOS.SYS /N11 /F5 DEVICE=C:\ASPIDISK.SYS Where N11 is 11/16ms and F5 is 5/16ms (default settings). The problem is resolved when we changed to N5 and F11. ---------------------------------------------------------------------- Thanks to everyone who sent me information for this FAQ. The people on comp.sys.ibmpc.soundcard have been very helpful--especially the kind sole who posted the FAQ from Media Vision. That document has contributed greatly to the troubleshooting sections of this FAQ. Right now, I'm going to keep this a mainly PAS-based FAQ. I don't know too much about other sound cards. But as I learn more in the future, I may incorporate more information about other sound cards into this FAQ.
