INPUT LEVEL control and indicators
This controls the overall level without altering the
relative settings of the Low, Mid and High frequency
Outputs. Input gain is +6 dB at "10". With signal
applied, set this control so the +4 dBu LED lights oc-
casionally, indicating sufficient signal. Flashing of the
OL (overload) LED during peaks can be avoided by
turning the INPUT LEVEL down.
