Okay so I've connected an extra pair of speakers to my receiver. I now have 7.1 but I'd rather have them as zone 2 speakers so I can use different inputs at the same time. I connected them to SP1 and SP2 but neither seem to work. I changed the settings to the internal amps SP1 and SP2 instead of external amp and still nothing. I changed the volume of zone 2 and the input using the zone control configs, anyone have any ideas? I just read somewhere that it doesnt output a digital signal to zone 2? is this true?!?!
