90 Watt/Eight Speaker Circuit Configuration
1) The AA-30 supplies audio power through plug P6, or terminals 5 and 6
on terminal block P8. (This audio power run is not supervised.) If using
the optional supervised return, a loss of audio power (due to a break in
the wiring) will generate a trouble signal at the AA-30.
2) If using an optional supervised return, cut resistors R8 and R9, located
directly below plug P6 on the AA-30.
3) Each circuit can handle a maximum of 30 watts.
4) In the configuration shown below, cut VCE-4 jumpers JP1 and JP2.
Overview
The following diagram shows typical wiring for a 90-watt, eight-speaker
circuit. The VCM-4 provides 30 watts and the VCE-4 provides 60 watts for a
total of 90 watts.
