Setting Gain Levels
The 4-segment input meters
are there to help you know
how loud your inputs are.
When you are adjusting the
gain knobs for each channel,
try to set your levels as loud
as possible without reaching
"0 dB." If your input
reaches 0 dB, you are
overloading or "clipping"
the IO|2 and this results in
severe distortion.
Ideally, your levels should
peak between -6 and -3 dB on
the meters.
