14. REMOTE CONTROL INPUT
By connecting a 15-pin D-SUB connector, it is possible to control speaker zone selection and activate the
chime via wired remote. Connection terminals for the remote are shown below.
Pin 1: Remote amplifier input signal hot(+)
Pin 2: Remote amplifier input signal cold(–)
Pin 3: Signal ground
Pin 4: Remote control 1(Speaker 1)
Pin 5: Remote control 2(Speaker 2)
Pin 6: Remote control 3(Speaker 3)
Pin 7: Remote control 4(Speaker 4)
15. PREAMP OUTPUT
This output connects the unit with an external power amplifier. Inserting a plug into the Preamp Out jack will
disconnect signal to the unit's power amp, sending the output of the internal mixer to the external amplifier.
16. AMP IN
This input connects an external mixer or preamp with the unit's power amp. Inserting a plug into the Amp In jack
will disconnect all input signal from the unit's internal mixer. Only signal from the external source will be heard.
17. LINK OUT
This line-level output connects the unit with an external mixdown deck or other recording source.
18. LINK IN
This line-level input connects the unit with an external mixer for expanded input channels.
19. CHANNEL INPUTS 1-6
These balanced three-pin XLR connectors accept a standard microphone cable or other low impedance
signal. Optional transformer balanced inputs are also available.
20. INPUT GAIN CONTROLS
These knobs provide continuous control of the input levels for each of the six input channels. When adjusting
the input gain, make certain that the levels are not set too high, or distortion will result.
The approximate levels for these controls are as follows:
