    sorry if this sounds dumb but is it possible to connect a power amp to an amp that i already have (swr550x) for more power? im not sure how all that stuff works.

    You can run the preamp out section of a small amp into a poweramp for more power. You cann't run the normal output of an amp into a poweramp to make it more powerful, unless you want an explosion.
  4. You can use your balanced XLR output or your effects send to connect to a power amp. I don't see a preamp output on your amp. When you do this you can use the power from your amp and the power amp in parallel (driving different speakers) but you cannot bridge or sum the power into one cab. As mentioned above DO NOT use the speaker outputs into a power amp or you will fry something!

    This jack's primary function is to send a post-EQ-and-SubWave™ signal to an external effects device for use in the 550x
    Effects Loop. However, it can also be used as:
    1. A line level output for use in conjunction with an additional (slave) power amp–such as SWR's
    Power 750.
    2. An unbalanced output suitable for recording or live mixing board purposes.
    The output impedance of the Effects Send jack is 100 Ohms.
