You can run the OMS ‘Test Studio’ utility by going to the ‘Studio’ menu and
releasing the mouse on “Test Studio”. Playing a note on your keyboard will give
you an audio message from your computer, “MIDI received,” while the arrow
pointing to the keyboard icon flashes. Clicking on a keyboard icon with the
mouse pointer will send a tone cluster to the QUATTRO MIDI output port. The
LED will light, and your sound module should play the chord.
You may now exit OMS Setup by quitting the application. The rest is up to
configuration within your music software. Generally, this means selecting “OMS
Compatibility,” or “Open Music System” for your MIDI system setup.
Hooking up your AudioSport Quattro
The Quattro provides four line inputs and four line outputs, and will accept a
+4dB balanced signal on 1/4” TRS plugs (tip-ring-sleeve), or a -10dB
unbalanced signal on 1/4” TS plugs (tip-sleeve). Each 1/4” jack will accept either
TRS or TS plugs.
You may connect the output of a line level instrument such as an electronic
keyboard or instrument preamp, the output of a microphone preamp (a mic
preamp is required for use with a microphone), or the output of a CD player or
similar line-level device. Check your device’s documentation for information on
its operating line level (+4 balanced or -10 unbalanced), and see the section,
“Using the Input Level and Output Level Switches” in this manual.
You may connect the four outputs of the AudioSport Quattro to a mixing console,
or use two of the outputs for a stereo send to a monitoring system (power amp
and speakers, or a home stereo), powered speakers, or a headphone amplifier.
Again, check your device’s documentation for information on its operating line
level, and see the section, “Using the Input and Output Level Switches.”
The diagrams below illustrate those scenarios. Typical Setup #1 shows the
AudioSport Quattro with a mic/instrument preamp plugged into Inputs 1/2 (we
suggest the DMP3 Preamp by M Audio), and a MIDI sound module’s audio
outputs plugged into Inputs 3/4. The four outputs of the Quattro are plugged into
a mixing board. Typical Setup #2 shows a CD player plugged into Inputs 1/2, and
Outputs 1/2 plugged into a monitoring system.
