The CompuPhase Sound
User's Guide

Thank you for your purchase of the CompuPhase Sound unit. Now you can enjoy
high quality speech, music and sound effects with your Microsoft Windows or
DOS programs.

After connecting the CompuPhase Sound unit to you computer and installing the
support software, CompuPhase Sound is fully compatible with Microsoft Windows
3.0 with Multimedia Extensions and Microsoft Windows 3.1. CompuPhase Sound also
comes with drivers for DOS and DOS programs that are compatible with the
CompuPhase Sound unit.


Connecting CompuPhase Sound to Your Computer
--------------------------------------------
Connecting the CompuPhase Sound unit is easy. The only tool you will need is
a small standard flat blade screwdriver.

1. CompuPhase Sound comes with two parts: the sound converter (plug with cable)
   and the speaker unit (the speaker box). Remove these parts from the box.

2. Open the battery panel at the back of the speaker unit and insert four
   1.5 volt penlight batteries. Close the panel.

   Alternatively, you can connect a 6 to 9 volt AC adapter (that does not need
   to be stabilized) to the speaker unit. If you use an AC adapter, check that
   the polarity of the plug matches what is indicated on the back of the
   speaker unit. Also make sure the voltage of the AC adapter does not exceed
   9 volt.

3. Locate the parallel printer port on the back of your computer.

   The parallel printer port might have a printer cable plugged into it. If it
   does, check to see if the cable is secured to the port by screws (either
   standard screws or larger thumb screws).

   If the cable is secured by screws, use a screwdriver to loosen the screw on
   each side of the connector, or twist the thumb screws counterclockwise by
   hand. Then firmly pull out the connector from the parallel printer port.

4. Plug the "pin end" of the sound converter into the parallel printer port.
   Secure the sound converter to the port by tightening the anchor screw with
   your screwdriver.

5. If you removed your printer cable from the parallel printer port, plug it
   into the other end of the sound converter unit.

6. Plug the sound converter cable into the speaker unit.

7. Place the speaker unit on a flat surface near the computer so you can
   clearly hear the sound.

8. Turn the speaker unit on. A read indicator, left of the on-off switch,
   should light up. If the indicator is not burning, the batteries in the back
   of the speaker unit are not well placed, or the polarity of the AC adapter
   is incorrect (see step 2).

9. Set the volume knop midway. The volume knop is located at the back of the
   speaker unit.

If your printer is plugged into the sound converter unit, the printer must be
turned on while the CompuPhase Sound unit is operating. Otherwise, the speech,
music, and sound effects may not sound right. This is caused by some printers
that cause the data lines of the parallel printer port to "float" in unstable
logic. Those printers are clearly not designed with pass-through plugs such as
the CompuPhase Sound convertor in mind. If no printer is connected, the
CompuPhase Sound unit will operate as it normally.


Installing the CompuPhase Sound Windows Driver
----------------------------------------------

These directions are for installing the Wnidows driver of CompuPhase Sound
under Microsoft Windows 3.1. Installation instructions for Microsoft Windows
3.0 with Multimedia Extensions may vary, please consult your Windows
documentation for further information.

1. Turn on your computer and load Microsoft Windows 3.0 with Multimedia
   Extensions or Windows 3.1 by typing WIN. If Windows doesn't start, try
   typing CD \WINDOWS and pressing Enter; then type WIN and press Enter. You
   should now be in Windows.

2. Open the Main window and double-click on the Control Panel icon. You should
   now see the Control Panel window.

3. Double-click on the Drivers icon. You should now see the Drivers window. To
   install the Windows driver for CompuPhase Sound, click on the Add button.
   You should now see the Add driver window. The box to the left of the Add
   window lists all of the current device drivers (sound, animation, video
   overlay, MCI, etc.) installed in Windows. The first item on the list,
   "Unlisted or Updated Driver" should be highlighted, if it is not, click on
   it now to highlight it and then click on the OK button.

4. You should now see the Install Driver window. This window asks you to insert
   the disk containing the Unlisted or Updated Driver into drive A:\. Put the
   diskette that came with CompuPhase Sound in drive A:. If you need to use a
   drive other than A:, substitute that drive letter for A:. Then click on the
   OK button.

5. You should now see the Add Unlisted or Updated Driver window. In the box to
   the left of the window "CompuPhase audio drivers for Windows 3.1" should be
   highlighted. If it is not, click on it now to highlight it, and then click
   on the OK button.

6. The CompuPhase Sound Setup window appears. Click on the appropriate parallel
   port that your sound converter is connected to: LPT1, LPT2, or LPT3 (options
   that you do not have will be grayed and you will be unable to select them).

   Select Exclusive playing if you're using a slow computer and want to try to
   improve the sound quality. When you select this option, Windows will not run
   programs or respond to user input while sounds are playing.

   Click on OK when you've made your selections.

7. The System Setting Change window should now appear. You have the option to
   restart Windows now to put your changes into effect, or to continue in
   Windows. Click on Restart Now. Windows will restart itself and activate the
   CompuPhase Sound Windows Driver.


Standard and Enhanced Modes
---------------------------

CompuPhase Sound's Windows driver works well in Standard mode with nearly any
computer and in Enhanced mode with a 25 MHz 386 or faster processor. Using the
CompuPhase Sound driver for Windows in Enhanced mode with a slower computer may
cause your system to slow down while sounds are playing, and in poorer sound
quality.


Testing CompuPhase Sound under Microsoft Windows
------------------------------------------------

Any .WAV file can be played through CompuPhase Sound with the Windows driver.
These sounds are in the format that Windows uses to attach sounds to documents,
spreadsheets, and other applications. To learn about attaching sounds to your
work, consult your Microsoft Windows manual for complete details. To listen to
the predefined .WAV files that are provided with Mircosoft Windows:

1. In the Main window, double-click on the Control Panel icon.

2. Double-click on the Sound icon. The Sound window should appear.

3. There are two boxes on the screen, the left box (Events) lists seven or more
   system events Windows allows you to attach a sound effect to. The box on the
   right (Files) lists the .WAV files and directories currently available to
   you. The four standard Wave files included with Windows (TADA.WAV,
   CHORD.WAV, DING.WAV, and CHIMES.WAV) should be listed here. Other .WAV files
   may be listed as well.

4. To hear any of these sounds, click on the sound in the Files box to
   highlight it and then click on the Test button. The .WAV file should play
   through CompuPhase Sound.

   If you want to assign a specific sound to a specific Windows event (starting
   Windows, exiting Windows, error, etc.), click on the event in the Events box
   on the left, and then click on the sound in the Files box on the right. When
   you click on the OK button, that sound will now be assigned to that Windows
   event, and will play when that event occurs.


Testing CompuPhase Sound under DOS
----------------------------------

Both .WAV files and .VOC files (Creative Inc. voice file) can be played with
the DOS drivers MEMPLAY.EXE and CPPLAY.EXE. To install and use the DOS drivers,
follow these steps:

Troubleshooting Guide For CompuPhase Sound
------------------------------------------

If there is no sound or if the sound seems wrong, check the following:

Are you using a software program that supports CompuPhase Sound?

    CompuPhase Sound is compatible with the following:
    - Microsoft Windows 3.0 with Multimedia extensions and Microsoft Windows
      3.1.
    - Programs designed to use "The Covox Speech Thing".
    - Programs specifically designed to use CompuPhase Sound.

    Check the system requirements for your software program and see if
    CompuPhase Sound is supported.

Are the files that you want to play in the correct format?

    The Microsoft Windows driver supports mono .WAV files digitized with 8 or
    16 bits per sample and a sampling frequency between 4,610 Hz and 44,100 Hz.
    Stereo files are not supported.

    The DOS drivers support 8 bits per sample, mono .WAV and .VOC files that
    are sampled between 4,610 Hz and 44,100 Hz. Stereo files and files
    digitized with 2, 2.3, 4 or 16 bits per sample are not supported.

    There are over ten "standardized" ways to compress .WAV files. The
    CompuPhase Sound drivers only support Logarithmic Delta Coding (LDC).

Can your operating system support CompuPhase Sound?

    CompuPhase sound is compatible with Windows 3.0 and 3.1. Through drivers,
    it is also compatible with DOS. When running in a DOS box under windows,
    you must install both the DOS and the Windows drivers. Otherwise some
    drivers will refuse to load or sound incorrectly.

    OS/2 is currently not supported.

Are the CompuPhase Sound converter and speaker unit properly connected?

    The CompuPhase Sound unit must be properly connected. Review the
    instructions under "Connecting CompuPhase Sound" to make sure you have
    followed all the steps correctly.

Is the led burning?

    If the led is off, there is a power problem. Either the speaker unit is
    not switched on, or the batteries are discharged, or the AC adapter is
    not giving the correct voltage or the correct polarity.

Is the volume level turned up?

    Turn the volume knob clockwise to turn up the volume.

Do you have headphones plugged into the speaker unit?

    The speaker is shut off when headphones are used. Unplug the headphones to
    hear sound from the speaker.

If you have a printer plugged into the sound converter unit, is the printer
turned on?

    In some cases, the printer must be turned on if you have it plugged into
    the sound converter. There are a few computers (especially Tandy models)
    where the printer needs to be disconnected from the sound converter for
    CompuPhase Sound to work.

Have you set up the software for it to use CompuPhase Sound?

    Sometimes you need to tell the program to use CompuPhase Sound and also
    what parallel port (LPT1:, LPT2: or LPT3:) to use. Check the software
    program's manual on how to set up the program to use CompuPhase Sound. If
    you need help in configuring the software to use CompuPhase Sound, please
    contact the publisher of the software.

Are you running any RAM resident programs (TSRs) or device drivers?

    RAM resident programs can sometimes cause interference with CompuPhase
    Sound performance. Try booting up your computer with a DOS system disk that
    does not have the CONFIG.SYS and AUTOEXEC.BAT files. Then try running the
    driver program MEMPLAY to test CompuPhase sound (see "Testing CompuPhase
    Sound under DOS").

If you've tried all the above suggestions, try using CompuPhase Sound and
software on a different computer.

1. If CompuPhase Sound does *not* work on the second computer, the unit could
   be defective. Exchange it for another at the store you bought it at or
   contact ITB CompuPhase at the address below:

        ITB CompuPhase
        Brinklaan 74-b
        1404 GL  Bussum
        The Netherlands

2. If CompuPhase Sound does work on the second computer, the first computer
   most likely has a defective or incompatible parallel port, please contact
   the manufacturer of the faulting computer.


Printer Port Use
----------------

The Windows driver for CompuPhase Sound blocks the printer port while playing
sounds. If a sound is playing, the printer port will be unavailable until the
sound has finished playing. If the Print Manager (or some other application) is using
the port, CompuPhase Sound will not be able to play the sound.
