    This is an embarrassing question... But I just bought a DBX 160A compressor. I have a Gallien Krueger Fusion 550, and I have no idea what so ever how to connect it to the amp. I know how to use a compressor from recording in the studio. But I never had to plug it into the amp. What input and outputs do I use? And I heard I "shouldn't" use the fx loops right?

    Take a patch cable, plug into your Effects Loop Out, plug into the input of the DBX, Take another patch cable from the output and plug into the Effects Return.

    Racks are perfect use for that Effects loop

    I think the effects loop is your best option.

    +2. This is exactly what the effects loop is for.
  5. i feel like this depends entirely on what you are using the compressor for. fattening a signal? or adjusting your dynamics? if you are trying to hit the preamp with a more even signal (ie as a limiter), you could put it in front. if you intend to use it to fatten up your amp (ie as a leveling amp), then the effects loop is optimal.

    Running a line level device into the amps input is a lot of signal.

    It's not that simplistic. If the output of the device is cranked all the way up, then yes that's "a lot" for any amp's instrument input to handle. But (a) most line level devices have a volume knob which can turn the output down to a level the amp can handle just fine, and (b) in this specific case the problem is not the output level at all--the problem is the strength of the signal going IN to the compressor needs to be strong enough for good reaction and good signal-noise ratio.

    That's why the FX loop is the right place for it.
