I would assume you would need to wire as shown in this picture...ask Edwin or Kingwa first to determine if any of the other required components are missing and if this is the only thing involved. I'm assuming your RCA's are just paralleled as the even on my DAC19-DSP the RCA/ACSS switch doesn't remove the RCA's from the circuit.

You don't need ACSS connectors unless you want to use Audio GD cables...of course ACSS only works with Audio GD amps/pre-amps that have an ACSS input.
By no means sure if this will work but might help you when you're speaking with Audio GD.
