STEREO SEC TI O N S
1 . STEREO I N PUTS
Each Stereo Input section comprises a pair of similar inputs.
The inputs are electronically balanced and separate jacks are
provided for the Left and Right source signals. A mono signal
may be plugged into the upper socket only for each pair to be
fed equally to left and right busses.
2. -10 SWITCH
The input jacks are normally set to match +4dBu nominal
signal levels. Pressing the -10 switch alters the input
sensitivity to match the -10dBV signals from most Hi-Fi
systems or semi-professional tape machines allowing the
inputs to be quickly switched to match, for instance, a cassette
player for pre-show music.
3 . EQ UA LI SA TIO N
Each Stereo Input is provided with a 2-band shelving EQ
section giving ±15dB boost & cut at fixed frequencies of 60Hz
and 12kHz.
