I am fairly new to home theater systems so excuse my lack of all correct terminology and likely many typos! We moved into a house that has a 5.1 Bose Acoustmass (so six total speakers) system installed and then speakers throughout the house. I bought a Pioneer VSK-1020-K 7.1 with the intention of using the multi-zone capability. There are three speakers in the front of the room (L, R, C). The acoustimass woofer is in the rear of the room with obviously the two surrounds (SR, SL). Here's the problem. I did get the multi-zone to work, which frankly surprised the heck out of me, however, after using the auto-calibration feature it doesn't seem like any sound is actually coming out of the front L and front R speakers. The center and surround L and R are working perfectly. It almost seems as though the acoustimass speaker is working instead of L and R, but C is loud. The auto calibration sets L and R volume to the highest level possible and when a movie or even the radio is on, iPod, etc. you have to literally press your ear up against L or R to hear them while C is very loud. SR and SL are as loud as C. Maybe this is normal it just seems sitting in the room that all the sound from the front is emitting from the one center speaker and then I have three speakers behind me all working fine and nearly overpowering the center. It sounds like un-surround sound! Thanks.
