Hello,
First post on this forum, so hi everyone.
I have not built any electronic projects for nearly 20 years so to say that I'm rusty on the theory side of things is not an understatement.
The idea is that the two stereo inputs needs to be mixed like PLII.
I have been trying to see if this passive surround sound decoder design http://www.dfad.com.au/links/DFAD_PASSIVE_SURROUND.pdf could be tweaked for the above number of channels and values, however I got stuck figuring out how to subtract the R channel from the L channel.
Any help is appreciated. This circuit will sit between a stereo pre-amplifier and a power amplifier.
