4.4 Channel Phases
In certain applications it may be necessary to reverse the phase of one side of
an incoming stereo source to correct for phase problems. There may also be
times when inverting the phase of a (mono) microphone may be necessary
to prevent phase problems with other microphones set up nearby.
For stereo inputs, the left output channel is inverted, if
L R
or
R L
has been
selected in the “Analog Inputs” menu ( see chapter 4.1 ); in the remaining (
R R
