I'm stupid. How does a crossover work, exactly?

    I once had impure thoughts. Oh, and I pluck my ear hair.
    Yes, I'm a putz and yes, I am embarrassed for having to ask this, but how does a crossover work? I have one on one of my preamps, but I am clueless.

    I understand that it is for bi-amping, but that's about it as far as my limited understanding is concerned.

    Help the stupid.

    it's like an eq. it cuts the signal very sharply of all frequencies above the crossover frequency in one channel, and all the frequencies below the crossover frequency in the other channel.

    It also allows you to control which decible range you want to send to what speaker. For an exampe with PA's your basic sytem is a three way system with subs, 15's w/ horn or tweeter. The X over would send the lows to the subs, the mids to the 15's and the highs to the horn/tweeter. I just learned this myself since we are upgrading our PA and currently researching this subject. It really cleans up sound.

    well either he means db range or else he just re-said what i said earlier :D. you -can- control the output level from a rack mounted pa x-over for each channel, although this generally is not available in amp-based models like planet boulder originally mentioned he had.
