INSTALLING THE AUDIO EXPRESS HARDWARE
21
Main outs
In a standard studio configuration, the main outs
are intended for a pair of studio monitors, but they
can also be used as regular outputs for any
purpose. Their reference level is +4dB. Use the
front panel VOL knob to adjust the Main out
volume. Push the VOL knob until you see
+main
LED turn red (or flash red) and then turn it to
adjust the main output volume.
S/PDIF
If you make a S/PDIF digital audio connection to
another device, be sure to review the digital audio
clocking issues, as explained in “Connect and sync
S/PDIF devices on page 22.
The Audio Express on-board mixer also supplies
12dB of digital trim adjustment for the S/PDIF
input pair, which can be adjusted from CueMix FX
(“Input trim on page 53) or the front panel (using
the same procedure as explained earlier for
Quarter-inch analog input trims” above).
CONNECT MIDI GEAR
Connect your MIDI devices MIDI IN jack to the
Audio Expresss MIDI OUT jack (Connection A
below). Conversely, connect the MIDI devices
MIDI OUT jack to the Audio Expresss MIDI IN
jack (Connection B).
Figure 4-3: Connecting a MIDI device to the Audio Express.
One-way MIDI connections
MIDI devices that do not receive MIDI data, such
as a dedicated keyboard controller, guitar
controller, or drum pad, only need Connection B
shown in Figure 4-3. Similarly, devices that never
send data, such as a sound module, only need
Connection A. Make both connections for any
device that needs to both send and receive MIDI
data.
Connecting additional gear with MIDI THRUs
If you need to connect several pieces of MIDI gear,
run a MIDI cable from the MIDI THRU of a device
already connected to the Audio Express to the
MIDI IN on the additional device as shown below
in Figure 4-4. The two devices then share the Audio
Expresss MIDI OUT port. This means that they
share the same set of 16 MIDI channels, too, so try
to do this with devices that receive on only one
MIDI channel (such as effects modules) so their
receive channels don’t conflict with one another.
