[QUOTE="Steve Kirby, post: 140327, member: 9411"] Re: How to connect Behringer Mixer Zynex QX1204USB to Sonic Exciter SX3040 What are you trying to do with all this stuff? Curious as to why you have a recording preamp and a mixer at the same time. You say you are only using one microphone. Is this for speeches? Singing with a band? If you are truly only going to use one microphone, the recording preamp/channel strip will serve to bring a microphone up to line level (to drive other equipment) and provide equalization. You don't need the mixer at all. A mixer is only if you have multiple sources that you need to mix together. Or if you need to control different outputs such as mains and monitors. Which brings us to the compressor. You can do a couple of things with it. But the important part is why did you buy it? What purpose were you trying to achieve? To limit peaks? To even out levels? To "squash" dynamics like folks talk about on recording forums? The last isn't really practical in small live sound. When you are constantly in gain reduction then as the input signal goes down, the compressor applies "make up gain" to bring the signal back up until the level dies below a threshold. This is akin to someone constantly turning the volume of the mic up and down and is a recipe for feedback as the compressor turns things up by itself. Now you could put the compressor in line between the mic preamp and the mixer and it would only affect that one input. But that is the most likely to cause feedback. And if you're running separate monitors any singer won't be able to tell how loud they are singing because the louder they sing (often trying to hear themselves over a band) the more the compressor limits it and the monitor doesn't get any louder. Singers have blown out their voices having well meaning but uninformed sound people compress their monitors. More likely you would put the compressor in line after the mixer (or preamp if you don't use the mixer). Although most pro sound people are not fond of "exciters", that would probably go last. Just before the power amp. This is a lot of stuff ganged together without a clear purpose. You are going to have to spend some time adjusting the output levels and input levels of the following stuff to make sure that nothing is getting overloaded but is otherwise at maybe 80% of full (ideally all the "fulls" should line up but this takes a lot of understanding to accomplish so leave a little margin at each step). The better you do this, the less noise you will get at idle from the system. And a bunch of stuff hooked in series will add noise. Mostly hiss. [/QUOTE]
