right output and inputs 13, 15 and 17 going to the left out-
put.
Sends and Returns
Both send 1 and send 2 provide up to 6 dB of post-fader
gain over Channels 1 to 12.
There are also two returns; one mono return and one stereo
pair. Return levels are controlled by the MONO RTN and AUX
RTN Left and Right pots. If you are not using the returns,
they can be used as additional unity gain inputs.
Turning a send pot all the way down will prevent any of that
signal from appearing at the send output, while turning it all
the way up will send it to the send output with 6 dB of gain.
Headphone Output and Phones Level
The left and right output signals are also routed to a stereo
headphone amplifier which has its own left and right volume
pots for convenient monitoring.
Master Level and LED Meters
The Master Level controls provide up to 20 dB of additional
gain. Since clipping doesn’t occur until approxi20 dB
and the noise floor is at -95 dB, this gives MicroMixer a
Signal-to-Noise (S/N) ratio of well over 100 dB. Because of
this, you can run the outputs at the +8 on the Master Levels
indicators (or slightly above) and still have digital quality sig-
nal.
Power Indicator
The MicroMixer runs on 9 to 12 volts AC. Whenever
MicroMixer is plugged in, the Power LED should remain lit. If
the Power LED goes off, check to make sure your wall supply
is properly plugged in.
