newb here, first post. I would like a simplified ACA wireing diagram to make the ACA one RCA only in, and only one Output. I want bridged mono only. I do not understand the use of the 39K resistor on the back panel. Do I need this for a simple monoblock? Thanks in advance.
It's all there in the explanations for building the various configurations. Even I did it after a little while. Good luck

If you are building two stereo amps, and bridging them into two monoblocks, you have to follow the switch and resistor in the back properly.
^ I don't believe that is correct. In XLR bridged mode, I believe the resistor is not in the circuit / bypassed.
gryhund - Mono RCA or Balanced Bridged or Mono RCA Parallel monoblock configuration?
The 39k resistor is needed for the Mono RCA Bridged configuration.
What it actually does is attenuate the signal from one amplifier board, before it is fed into the second amplifier board, when the switch is flipped to activate that mode of operation. Oversimplified...
I mean no disrespect, but if you're unsure, I'd strongly advise building it precisely per the guide.
I'd recommend that at least one other person confirm, since you've been given two opinions. Mine is less likely to be correct, but... I feel pretty confident.
Edited to try and use the same terms as in the build guide. It sounds like you want Mono RCA bridged. Also... adason is correct... it is needed for the RCA bridged configuration. Just not the Balanced / Bridged. Apologies Adason.
