direct input signal with Inputs 1 , 3 , 5 , and 7 in the left channel and Inputs 2 , 4 , 6 , and 8 in the right
channel. This is useful if you want to directly monitor a stereo mic setup such as a stereo signal from a
keyboard, or overhead drum mics. Put this switch in its depressed position (green
Mono LED is lit) to
monitor the direct input signal with all inputs summed and heard equally on each side. This is useful for
monitoring a guitar or vocal mic signal. This switch does not affect the DAW playback or how your
sound is recorded into your DAW; it affects only how you hear the input signal in the
