Hi there - first post (hopefully of many)...
Just bagged myself a very nice Yamaha RX-V673, which is great. However, slight problem with my (somewhat old) Eltax 4.1 speakers. I've run connections through to the lower ports on the back of the speakers from (what I believe are) the subwoofer points in order to get a response to the bass speakers, to the Surround Back/Bi-Amp jacks
I've also made a change in the settings in the menu - as suggested - to 5ch BI Amp but still nothing.
I'd be grateful if you have any suggestions.
