Hooking up the Multimix USB
This diagram will help you get the Multimix USB hooked up and
ready to go. The equipment you use depends on personal
preference and on whether you’re performing live or recording.
For example, you’ll see below that the MAIN MIX OUT can be
routed to a recording device for recording, or to a PA system for
live performance.
Using Proper Cables
When connecting instruments and other equipment to the
MultiMix, it’s important that you use the appropriate types of
cables. Here are some simple but important guidelines:
y
For the mic inputs, use XLR cables.
y
For the line inputs and all other 1/4” connections, use 1/4”
mono TRS cables.
y
Use stereo RCA cables for the 2-track in and out.
Be sure to follow the
guidelines for which cables to
use (further down this page)
and the procedure for setting
levels (on the next page)
before you begin mixing.

y
Use a USB cable to connect the USB port to a computer.
Do not use a USB hub, as hubs can introduce timing
glitches in USB communication.
y
For the S/PDIF Digital out, we suggest that you use a
coaxial cable that is specifically designed for S/PDIF
applications. These cables are better suited for high
frequency (digital) signals and are unbalanced, shielded
coaxial cables with shielded RCA connectors on each end.
Better to get the high quality S/PDIF cables and save
yourself some unnecessary grief.
Setting Levels
Before you can begin mixing different audio sources with your
MultiMix, you must set the level for each channel you’re using.
This helps to prevent distortion and clipping. Here’s how:
1. Slide the channel fader to unity gain (0).
2. Turn the AUX SEND and GAIN controls all the way down,
and turn the EQ knobs to the center detent (you’ll feel a click).
3. Connect the source of the signal to the channel’s input.
4. Press the PFL / SOLO switch on the channel.
5. Make sure the SOLO MODE switch in the master section is
set to SOLO.
6. Play the instrument at a normal level and watch the LED
meters in the master section.
7. Adjust the channel’s gain until the LED meters remain at or
very close to 0 and do not 6dB.
8. If you need to apply EQ, do so and check the meter again.
