B&W 801 Series 80 Bi-amping

I found the schematic on the net, It is a parallel xover design, you can disconnect the 6.5mH coil from the input (marked X in red) and wire it to the positive side of a new set of blinding posts, that will be the LF input for bi-amp and the existing blinding posts will used for HF and MF input.

What about the negative imhififan? Cut the negative right next to the positive red X and put the wire to the (added 2nd) negative binding post? :-) That will work, ay?

Regards.

Ok, so this looks like an internal wiring job. Thanks for confirming this is way beyond anything I’m willing to attempt. Single channel it is.

@oldhvymec , thanks! I forget to mention the negative binding post, it need to cut the trace on PCB to separate LF negative from MF and HF negative connection.

That looks good the me..:-)
