    Greetings!

    I am curious about possibilities of using an
    integrated bass head with the addition of a
    power amp to drive more speakers/volume.

    For example: If you had an Eden WT400, could
    you run a line from the 'preamp out' to
    a QSC poweramp and drive more speakers w/o
    any kind of performance degradation? Would
    you still be able to drive speakers w/ the Eden's
    amp at the same time w/o diminishing
    sound?

    Follow-up question: How much are the preamps
    in, for example, the Eden WT400 and the Eden
    Navigator or say an SWR350 and a Grand Prix?
    I'm guessing the separate preamps sound better,
    but what's the real scoop?

    Thanks!

    ok... if you have a preamp-out and a slave in, you have no problem.. Most poweramps, atleast i know my mackie, has a through out that puts out exactly what you put in.. so you could go from your preamp, to the poweramp, then to the slave out. I'm pretty sure that engaging the preamp out would disengage the rest of the amp unless you use the slave in also. Definately worth making sure before you pay for everything... the other option would be to use the effects loop... effects out to poweramp, poweramp parallel out back to effects in... i believe it should work fine....

    i'm not sure about all of them, but the ampeg/SWR preamps are around the $600 range, and i'm not sure about sound quality, but they normally have more knobs and buttons than most of the integrated heads that their respective company makes, which would elude to atleast more sound options....

    Hi Captain wally,
    Sure I've done that quite a bit running a line from my pre amp out on my SVT200T into a power amp to push more speaker cabs. Works great!
     
  4. so you can buy a power amp
    from your amps Pre amp out jack run it into your poweramp then from the power amp into sum cabs?

  5. Yes.
     
  6. The only reason for you to get a seperate pre-amp would be if you're not getting a sound you like. THe only reason the y make seperates, as with Hi-Fi seperates is to give you more options. Sure the sound quality is generally better than integrated amps, but you can still get an integrated system that works as good as the best seperates system you can buy!

    Ask yourself: Does my sound need anything new? If so, go get it!
