TAPE/AUX. LEVEL (24)
Controls the level of signal patched into the Tape In jacks or into the Auxiliary input. Using the Auxiliary
input jack defeats the Tape In jacks.
9-BAND GRAPHIC EQ (25)
Provides ±12 dB equalization at each center frequency.
OPERATION NOTE: This equalizer is designed to provide room equalization, feedback control and system
tone control. No amount of equalization will correct an acoustically bad room/mic/speaker arrangement or
completely correct the response curve of a poor loudspeaker. Always begin with all sliders in the "0" position
and avoid excessively cutting large segments of the audio passband, which would limit the system's dynamic range.
CAUTION: TAPE OUT/TAPE IN
Before placing connected tape decks in the 4'record" mode, set the Tape/Aux. level control to "0" or
off. Most model tape decks feed the input signal directly to the output when in the record mode. This creates
a "closed loop" condition from the Tape Out to Tape In jack. The resultant feedback or high pitched squeal
can be avoided by setting the Tape/Aux. level control to "0".
TAPE IN JACKS (26)
These two jacks provide a paralleled input for proper mono mixing of stereo tape deck outputs. For monaural
tape sources, use either jack. These inputs are defeated when the Aux. input is used.
TAPE OUT JACKS (27)
These two jacks provide the same monaural signal to be supplied to the left and right inputs of a stereo tape
deck. Output level is determined by the Tape Out level control.
PILOT LIGHT LED (28)
Illuminates when AC power is being supplied to the amp.
