Typical wiring of two AA-120s using one AA-120 as a backup:
Unamplified
low-level audio
(Twisted-pair,
14-18 AWG)
DVC-AO Outputs
1, 2, 3, or 4
(See DVC Manual for
details)
Note: Cables must enter from top of the plug.
*Note: If not using Class A low-level audio return, an R-470 resistor assembly may be installed across P3, pins 4 and 5 of the last
directly connected device on the low-level audio riser; this may help to calibrate the audio amplifier.
