Input Parameters for Mono Channels only :
PHASE Two positions are provided (select either with the key or the rotary):
• NORM/Off, in phase (default setting).
• REV/On, out-of-phase.
Input Parameters for Mono and Stereo Channels:
GAIN Input gain can set in 1 dB steps from –24 dB (attenuation by 24 dB) to +24 dB.
Default value: 0 dB.
In a stereo channel, left and right input gains are treated si multaneously.
Input Parameters for Stereo Channels only :
PHASE Four different positions are provided:
• + +, in phase (default setting).
• – +, left channel (or input A) out-of-phase.
• + –, right channel (or input B) out-of-phase.
• – –, left and right channels (or inputs A and B) out-of-phase.

MS on/off Two different positions are provided:
• MS off (default setting), for coincident XY stereo microphone setups.
• MS on (Mid/Side information), used for decoding MS information from
appropriate coincident stereo-microphone arrays.
2 CH MODE Five different positions are provided:
• Stereo (default setting).
• Left and right signals are swapped.
• Left signal only is routed to both left and right outputs.
• Right signal only is routed to both left and right outputs.
• Mono, left and right signal mixed together (–3 dB) and routed to both left
and right outputs.

If a channel contains the input balance function (configuration tool name
‘Input MS mode Bal Phase’), a balance control will be available in the pan
page. This balance control is actually set
before
the mono switch in the signal
path, within the input section of the channel. Hence it is possible to use the
