5.6 Basic Operation
These controls are on the rear panel of the 402C or
802C II systems controllers.
INPUT LEVEL
These switches for each input channel adjust the
sensitivity between -10 dB and +4 dB (Figure 17).
To find the nominal output level of the output device
(mixer, signal processor), consult its owner’s guide
or call the manufacturer. Set the controller INPUT
LEVEL switch to the closest number possible.
Do not to overload the inputs of the controller. Set
the INPUT LEVEL switch, and adjust the output
device’s control(s). Keep the signal below the
controller’s maximum input level (+4 dBm or 1.23V
RMS).
