3-6 Parameters SW V3.3 Date printed: 05.08.03
Input Parameters for Mono Channels only:
PHASE [1] 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 [2] 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 simultaneously.
Input Parameters for Stereo Channels only:
PHASE [3] 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 Mode [4] 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 [5] 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.
