    I need a power amp to run JBL SoundFactor 15 inch bottoms and pair of
    auxiliary monitors for a regular 3 piece rock band set up, and I see
    good deals on ebay for the Gemini GPA-2000 2000watt power amps,
    wondering if they are suited for bands, or just DJ/mobile Dj'ing.
    Thanx

    All 'DJ' amps are rubbish.

    Get yourself something decent that's actually *pro-audio* ! DJ gear isn't even
    remotely in the same league.

    it might work for a while before it blows... but not very well

    the GPA-2000 power rating is 85 to 110 watts per CH into 8 ohms depending on
    which ad you look at. the 2000W is a misleading come-on

    My own experience with some Gemini CD players at an install lead me to
    scratch Gemini from even the long list of potential suppliers of audio
    kit. There really aren't any good deals on Gemini kit.

    That model number must be based on the year somebody designed it,
    because it has nothing to do with the amp's actual power:

    Specifications:
    85w RMS (170w peak) per channel at 8 ohms, 110w RMS (220w peak) per
    channel at 4 ohms, and 220w RMS (440w peak) at 8 ohms bridged

    They are pretty flimsy in construction, and have badly undersized power
    supplies, but I have seen worse. Note that the power ating is, well,
    just not very realistic.

    Because of the undersized power supply, I think that 85W RMS is optimistic
    and I bet it doesn't hold across the whole passband. Probably valid at 1KC,
    though.
