I am considering buying the yamaha htr-5760 as an entry-level home theater/music stereo receiver. It's right for my price range (around US $350), has gotten good reviews on several sites, and appears to pack in a decent amount of features.
One of those features is the YPAO, which basically is Yamaha's auto-calibration microphone system. Based on some other forum postings, it seems that this YPAO is surprisingly useful for neophytes like myself, so I would be looking to utilize this feature. Reading the manual pdf, however, it seems that the auto setup will not function if the receiver is connected to any less than the full receiver capacity of 10 speakers (for their DSP, yamaha adds two "presence" speakers to a 7.1 setup).
My question, finally, is directed to anyone who owns an HTR-5760, or has experience with them: As I will be using a 6.1 speaker set, I am interested in knowing if other users have been able to use the auto-calibration with less than 10 speakers. Can you connect less than 10 speakers (no presence, and only one surround back) and still use the YPAO?
