Unimode 400 Installation PN 50710:A 10/22/97
When wiring circuits in a dual-channel configuration using 120 watts of power with
four AA-30s, note the following:
1. AA-30 audio power is drawn from plug P6 or terminals 6 and 7 of terminal block
P8. (This audio power run is not supervised.) If using the optional supervised
return (plug P7, or terminals 2 and 3 of terminal block P8), loss of audio power due
to a break in the wiring generates a trouble signal at the AA-30.
2. If using an optional supervised return, cut resistors R8 and R9 on the AA-30 (for
location of R8 and R9, see Figure 4-39).
3. Maximum power per circuit equals 30 watts.
4. For dual-channel operation, cut VCE-4 jumpers JP1 and JP2 (Figure 4-39).
Figure 4-39 shows typical wiring for a 120-watt (using four AA-30s), dual-channel
configured circuit:
