    My Pioneer Elite vsx-45tx has been running fine but yesterday when I was watching The Punisher in Digital EX (6 channel) it started powering off at high volume (around -20). Its been running fine up to -12 level with 5.1 Digital Dolby. Although I don't have the rear center hooked up the display still shows that all 6 channels are active.

    Any pros here have suggestions, ideas? How do I over come this problem?

    I'm starting to wonder about getting a 3 channel amp for the 3 front speakers. I have to say that I'm a little disappointed because I read several comments about Pioneer VSX receivers having more than adequate powers for their ratings.

    My speakers: Front main: Paradigm Studio 20; Center: Paradigm Reference Studio CC; Rear: El Cheapo Sherwood mini HTIB speakers; Sub: Tempest with 370W plate amp

    I may be wrong, but I believe this problem only ocurred among older 45tx units. I think they identified the problem and fixed it upon shipping out their next batch. I think you're going to have to contact their support and have this fixed.

    I had some problem w/ my 6ohm (dip as low as 4ohm) Swans Diva 4.1s shutting down my 43TX. To get around it I used the bi-amp feature in which each amp channel saw a higher impedance. The speakers you have shouldn't be that hard to drive unless the backs are maybe 4ohm.

    NicholasL,
    How do I know if mine is of the older batch? Is there a manufacture date range to identify from?

    Thanks
