Hi
I am currently building two of these boards for a pair of mono blocks- bridged mode....
Now the more I read the instructions, the more I get my wires crossed :)
One needs to be in inverted, one in non-inverted - but neither match the job Myers for bridged mode + also needs to be in parallel?
Probably straight forward but can some kind person let me know where the two wires of the one RCA goes and the red / black of the one speaker - and jumpers.... Pleaseeeeee :)
I will try and attach two pics to help...
Many thanks
Tony

Hi P-A
Yes, but I've probably over complicated things in my head to much....
Basically - the one RCA in, do I connect the '-'to two of the wago points and same with the '+'  ?
The speakers as per the bridged diagram but what about the jumpers?  Both as bridged? Or one inverted one non?
Cheers

Thanks P-A!
I'll try that!  And the RCA in on jp5?

The JP5 is the output. Please check also the schematics. The RCA, of you mean the input connector, or what?
