In Reply to: RE: the idea is borrowed from BH Foreplay ver.1 ... posted by Tre' on June 30, 2017 at 07:20:59:
The 4.7k isolation resistors seem to be a VoltSecond Foreplay mod idea, but he said that if both output are being run at the same time, the 4.7k value can be dropped down to 100 ohms.
The basic idea is to provide a bit of isolation between the two power amp inputs.
My powered sub has a 3rd order low pass filter built in, so no extra filtering is needed.
I'll probably try lower ohmic value isolation resistors and hear if anything changes.
