  1. Hey all.I have just purchased an aguilar db680 pre amp.the thing is amazing and it has given me the sound i have wanted for years.i will never part with this thing.my problem is a power amp.i want to get a qsc 3002 power amp,900 watts a side and 3000 watts mono i think.but i have read a lot of people are having problems running pre and power amp setups,problems with volume and so forth.could you give me youre opinions please,any help would be great.i play mainly five string basses through a rig which comprises of a swr 1x15 and an swr 1x18 if this makes any difference.

    What exactly are you worried about?

  3. In reference to ampeg SVPCL post???

    Most of these recent posts are due to user error, 3000 watts is rediculously more than u'll need. Some errors are due to setup switches in back or output gain from the pre not being enough which is fixable etc etc.

    If you have problems we can help, but don't be afraid of the pre/power setup

    800+ watts and those cabs, you should be able to play anywhere you want. what have you tried it through so far?

    no personall experience w/ QSC, but i know it's good stuff and been around a while.
     
  5. If ur asking me specifically:
    for power amps i've worked with QSC and Stewart.

    For pres i've played with ampeg svpcl, swr grand prix, and an aggie... can't remember which one exactly if there is more than one.... it's my roommates so i can check when i get home.

    I left pre/power because i loved SWR and GK and at the time didn't know GK made a pre and couldn't find the electric blue.... =(

    I want to move back to the pre/power setup when i can find an SWR Electric Blue =( alas i can't seem to find one. Add in the ampeg SVPCL and my now discovered gk2001rbp and i'll be in heaven.

    The QSC power amps require a higher voltage input to acheive full power than some of the commonly used amps.

    The 680 should be fine though.

    I use a banana (amp end) to Speakon (cab end) cable.

    If you use Speakon connectors at your cabs (and with 3000W I would highly recommend that you do), make sure you have the connections correctly wired at the amp end.
    If you use Speakon(s) at the amp end and are running in bridge mode, make sure the connection pins are wired correctly (I believe it should be '+1' pin = the positive side and the '+2' pin is the negative side).
    You can check the QSC PLX manual online to make sure.

    Make sure you set the dip switches on the back of the amp correctly as well.

    Nothing to it.
