8 Audio Amplifiers—Audio Amplifiers (AA-30)
Figure 3: AA-30 Front Board Terminal Assignments
Notes: The audio output (Terminals 5 and 6 of P8 or P6) is not supervised.
Looping the audio output and connecting the return circuit to
Terminals 2 and 3 of P8 or P7 provides supervision unless the
audio output is wired Style Z by returning (looping) the audio
output circuit to Terminals 1, 2, and 3 on P8. Therefore, the
speaker circuit control device (XPC-8 or M510CJ) must be located
in the same cabinet as the amplifier.
