PA03 in bridged mode
« on: January 10, 2016, 07:37:10 PM »
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

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