thedorts Posted October 31, 2008 Posted October 31, 2008 Hi all the manual is a bit unclear, does anyone know if you can Bi-Amp front speakers on a 5.1 main setup and still run 2 speakers on zone 3 (SP2)? any help appreciated.

Ive got an RX-V2700 and run zone 2 without bi amping but do not see why it wont work, the bi amp uses the surround back channels so the surround channels should still be available to share with zone 2/3 which probably means you lose your surrounds when the zone is active ,tell us the results as if I change speakers I might look at doing the same configuration

Yeah ,looks like you are right, i just activated bi-amp in mine and the option to select int on the zones are grayed out and only external is available,if you want the extra zone(s) forget the bi-amp, not that much of a loss anyway.

tonymy01 Posted November 4, 2008 Posted November 4, 2008 It is using 2 amps. The receiver has 7 amps internally. It is just using the amps destined for the other zone and/or the 7.1 surround rears as the other amps for the front. It must have the same output power on all 7 amps I suppose to achieve this properly. Regards
tonymy01 Posted November 4, 2008 Posted November 4, 2008 That is just it, DACs aren't needed for amps. DACs are for the output of the channel processing in a 7.1 system. The amps are just the last bit of the chain. If you look at the service manual it makes the signal path a bit clearer, but essentially the digital input gets processed and pumped thru 8 Digital to Analogue converts and then thru some switching circuitry to the amplifiers for final output (well, not the sub, it would go to a buffer to the non-amplified sub output only). So presumably the bi-amping would use the same DACs for the front speakers in a normal 7.1 system, and "bridge" it thru the switching ICs to the second amp pair. You can even hear a relay kick in for certain things the Yammie does, when you go to 2 channel mode for example, I would guess this bridges 2 amps together, similarly for the testing for the presence speakers, it switches a relay for that, presumably to take the output of 2 of the amps to different speaker sockets for the presence speakers. So the bi-amping might even use a relay to do the trick rather than switching ICs. Regards
