Page 48: Functional Description
Processor FAULT COMM The 8910ADA-M Analog Audio DA module is an analog audio distribution amplifier (DA) that has one balanced bridging input. The input can be amplified over a range of -12 to +30 dB by setting an eight-position jumper that has 6 dB gain change per step. -
Page 49: Analog Circuitry
Each differential output has a dual amp IC to drive the outputs. This provides high isolation between stages. All analog audio stages are powered from the filtered ±12 V supplies to have enough head room to meet the +30 dBu maximum specification for input levels. 8910ADA-M/ST/SR — Instruction Manual... -
