Routing
Following illustration gives an overview of possible routings between the AMP IN audio inputs
and the SPEAKER OUT audio outputs using the internal relays of the device. The PVA-4R24
includes four 2-in-6 routing blocks A, B, C or D. Each routing block provides 2 regular inputs, 1
spare amplifier input and 6 outputs.
Spare amplifier input S1 of AMP IN A (C) is for replacing the amplifiers connected to inputs 1
of routing blocks A (C) and B (D).
Spare amplifier input S2 of AMP IN B (D) is for replacing the amplifiers connected to inputs 2
of routing blocks A (C) and B (D).
