Warning
This equipment generates and uses radio frequency energy,
and if not installed and used properly (i.e. in strict accordance
with the manufacturer’s instructions), may cause interference
to radio and television reception. It has been tested and found
to comply with the limits for a Class B device in accordance
with the specifications in Subpart B of Part 15 of FCC Rules,
which are designed to provide reasonable protection against
such interference in a residential installation.

including interference that may cause undesired operation.

iv
Only peripherals (computer input/output devices, terminals,
printers, etc.) certified to comply with the class B limits may
be attached to this equipment. Operation with non-certified
peripherals is likely to result in interference to radio and TV
reception. Furthermore, the use of a non-shielded I/O cable
with this device will not enable the device to meet the
minimum emission limits mandated by U.S. federal law.
There is no guarantee that interference will not occur in a
particular installation. If this equipment does cause
interference to radio or television reception (this can be
determined by turning the equipment off and on), the user is
encouraged to try to correct the interference by one or more
of the following measures:

circuits.
If necessary, the user should consult the dealer or an
experienced radio/television technician for additional
suggestions. The user is hereby notified that changes or
modifications not expressly approved by Mediatrix
Peripherals Inc. could void the user's rights under the limited
warranty.

Introduction
Wavetable & FM Synthesis Break the Sound
Barrier
The audio performance standard for the PC has been raised
again with the introduction of the Audiotrix Pro. This brand
new sound card is based on the Yamaha OPL4 chip set which
contains Wavetable and FM synthesis. Wavetable synthesis is
based on the digitized recordings of actual instrument sounds
while FM synthesis is based on the manipulation of sine
waves. The Audiotrix Pro permits 24 voices of Wavetable
sound and 20 voices of FM sound to be output
simultaneously. The result is a new height in audio
performance that has no equal in the PC marketplace today!
The Audiotrix Pro
In addition to Wavetable and FM synthesis the Audiotrix Pro
also features:
•A standard general MIDI voice bank on a 2 megabyte
mask ROM.
•A 16-bit audio codec which provides a complete
MPC and Microsoft Windows Sound System solution
while remaining backward compatible with the
original industry standards Ad Lib and Sound Blaster.
•An optional Effects Processor is also available as a
daughter board to the Audiotrix Pro which provides
even higher quality sound with the addition of such
effects as echo, reverb, flange, distortion, panning and
surround processing.

The Manual

installation, and explains how to use the software included to

•Jukebox, a music playback program that includes a
music clip library in a variety of styles, and that lets
you listen to songs you want from standard MIDI

•PLAYMIDI, a utility program used for playing back
MIDI files from the DOS command line or from a
batch file.
•PLAYWAVE, a utility program used for playing back

Chapter 1
Quick Start
This Quick Start is intended for the experienced PC user who
has already installed and used various hardware devices and
software applications. Do not attempt a quick start
installation if you are not familiar with the PC environment;
installation errors could occur that will be difficult to correct
afterwards. This Quick Start includes references to the
User’s Guide for those who need complete information on a
particular hardware or software installation step.
Installing the Hardware
Installing the hardware involves two main steps:
•Install the Audiotrix Pro Card
•Connect the Other Peripherals
Install the Audiotrix Pro
1. Make sure that the on-board jumpers —the joystick
selector jumpers and the microphone selector
jumpers, are in the desired position.
qSee “Description of the Audiotrix Pro Card: Layout
of the Card,” and “Getting Installed: Hardware
Installation.”
2. Plug the Audiotrix Pro card into the computer in a
free slot as far as possible from the video adapter
card.
NOTE: Certain cards, such as video adapters,
produce high-frequency signals that can interfere with
the sound quality of the sound card.

qSee “Getting Installed: Hardware Installation.”
Connect the Other Peripherals
•Plug external speakers into the main audio output of
the card, or connect the output to the input of a stereo
system.
•Connect a low impedance dynamic microphone, or an
electret microphone, to the microphone input of the
card (making sure that the microphone selector
jumpers are in the position corresponding to the
microphone).
•Connect the output of the stereo source (CD player,
CD-ROM drive, synthesizer or cassette player) to the
stereo auxiliary input of the card, using a stereo cable.
•Connect your joystick to the DB-15 game port of the
card. If you plan to use the MIDI interface, connect
your MIDI device with the Audiotrix adapter cable.
qSee “Getting Installed: Hardware Installation.”
Installing the Software
Installing the software involves two main steps:
•Install the Setup Disk
•Install Audiotrix Applications and other bundled
programs
