Quick question, are Pioneer SX- series receivers common ground?
I have SX-780 and SX-880 that I'm planning on using for the SDA's.
I'm pretty sure they are common ground but want to confirm just in case before I blow anything up. :eek:
Thanks

    Hello Mystery,
    In looking at the SX-880 and SX-780 schematics they would be fine with a common ground speaker system.

    I'm not aware of any 2 channel receiver or AVR that isn't common ground. Ken, do you know of any that aren't common ground?

    Thanks for confirming Ken.
    :cool:

    Unrelated but I think I just blew woofers on a set of test speakers running 25hz tone in high volume from the SX-880. :eek:
    My first blown speakers.
    Good thing they are cheapo speakers.

    I believe when Polk first introduced the original unpowered SurroundBar (which is a common ground speaker) there was an H-K receiver (pretty upscale model) that wasn't compatible. But, only a few people had problems. That's the only one I can remember.

    I don't have large enough room to try high power amps on them.
    The SX-880 really sounds nice with SDA-2B's.
    I can't go higher than 1/4 volume in normal listening levels.
    I checked output meter and it was above 1 watt every now and then otherwise less than 1 watt. :eek:

    And when I need more low end, 'Loudness' really kicks in so much bass that I feel like having a subwoofer.
    I know it's not good to use 'Loudness' for music but I watched few trailers of new Star Wars and Oblivion movies with that on and the whole floor was shaking. :lol:

    SDA for movies... feels like a theater. :mrgreen:
