When wiring eight speaker circuits using 90 watts of power, note the following:
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 four-wire 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.

Figure 4-35 shows typical wiring for a 90-watt (VCM-4 provides 30 watts and the
VCE-4 provides 60 watts for a total of 90 watts), eight-speaker circuit:
