    Right so i was thinkin about buying some sort of a preamp, be it a tech 21, pod, ampeg bsp, wotever and connecting it to a power amp like a qsc and then into into a speaker cabinet. Easy peasy.

    I understand the differences between pre/power amps etc. but at the moment i'm currently playing through a bi-amp GK, and i like the idea of the bi-amp, so i was wondering if u had a pre/power setup and a bi-ampable cab like one of the GK's how would you use its bi-amp capability, would u need to buy a seperate crossover for your rack, or do some power-amps come with built in crossovers? (or even do any cabs come with built in crossovers??(maybe a mesa powerhouse??))

    Cheers for your help

    Some amps do come with a crossover, or have the option of installing one internally. But tthe G-K cabs use a much higher crossover point than many PA-oriented crossovers are typically set up for. Do your homework...:cool:

    If there's one in the cab, it's always passive unless you're talking about a powered cab.

    No question is a stupid question. It's a quest for knowledge, therefore, questions are smart.

    All of my biamp setups have the crossover in the preamp, not the power amp. Hard to find newer preamps with crossovers; I have an Ashley BP-41, a BBE 383 and a Yamaha PB1; they all have internal crossovers that drive stereo power amps. These are all pretty old, but you can find them on ebay sometimes.

    Eden Navigator preamp has built in crossover as well.

    Excellent pre.

    The Aguilar DB680 has a crossover also. I initially started my pre/power combo with a preamp and changed back to full range. Since my cabs put out great full range tone, I didn't feel I gained alot with the separation going into standard full range speakers...

    Since the advent of good "full" range cabinets containing decent drivers and well designed crossovers, bi-amping is no longer a much needed thing. It involves extra power amps and complex filter circuitry to accomplish. IMHO bi-amping is a hold over from a bygone era.
