1) SENSITIVITY TRIM (SENS.) Sets the microphone trigger level when DIM or MUTE is selected.
2) DUCKING This switch selects one of three options that determine how microphone announcements
affect the music level:
NONE - No ducking
DIM - Automatic 10 dB music level reduction while speaking into the microphone.
MUTE - Automatically shuts the music off when speaking into the microphone.
3) MIC Adjusts the microphone level (equally distributed between left and right outputs).
Ducking does not affect this level.
4) STEREO 1 STEREO 3 Adjusts the level of the STEREO RCA inputs. These inputs are suitable for CD players,
tuners, TVs, VCR audio, etc.
5) BASS Over all adjustment of low frequency levels.
6) TREBLE Over all adjustment of high frequency levels.
7) MASTER Adjusts overall level of all the mixed audio sources. Adjust to provide a suitable signal level to
the PLC4.1 controller or other following amplifier. Unity gain of the mixer is provided when STEREO input
and MASTER output levels are at 12 o'clock.
