19) Tape output RCA jack. An audio output to supply signal to a tape recorder. This signal is
pre tone control and pre master volume control so that changing sound reinforcement level
requirements do not affect the recording level.
20) Booster output RCA jack. This output supplies the audio input signal to an additional
“booster” or power amplifier. This signal is after tone control and master volume control. In this
fashion, very large systems requiring more than 120 watts can be accommodated with an
additional booster amp.
21) AUX-3 input RCA jacks High impedance input available with parallel RCA jacks (for
combining stereo output accessories).
22) MIC-6/AUX-3 input selector switch. Allows for selection of either low impedance MIC-6
input or high impedance AUX-3 input.
23) AUX-2 input RCA jacks High impedance input available with parallel RCA jacks (for
combining stereo output accessories).
24) MIC-5/AUX-2 input selector switch. Allows for selection of either low impedance MIC-5
input or high impedance AUX-2 input.
25) AUX-1 input RCA jacks High impedance input available with parallel RCA jacks (for
combining stereo output accessories).
26) MIC-4/AUX-1 input selector switch. Allows for selection of either low impedance MIC-4
input or high impedance AUX-1 input.
27) Loudness on/off switch. Loudness adjustment for AUX-1~3, +8dB @100 Hz,+4dB @10
KHz.
28) MIC-4 (XLR connector) input. Accepts a balanced low impedance microphone signal with
an XLR connector.
