It can only be connected to a PC by analog means. It has a stereo pair for main outs and stereo pair for control room outs (1/4 inch), although I suppose you could use the tape out RCA pair if you felt like it. So the most you're ever going to get out of it is a pair of mono signals, one panned left and one panned right. You will still need an interface that converts those signals from analog to digital so you can do stuff with them in your computer. The built in sound card is not recommended as an interface for quality reasons. If your main goal is recording, then unless there is a specific reason why you need a four channel mixer, I would consider returning it and getting a 2-4 channel interface. I think they start at around 150 bucks at the low end. M-Audio. RME. etc. They will allow you to record 2-4 channels directly and independently into your computer and you do your mixing using the free software that is usually provided with the interface. Search this forum for interfaces, you'll get plenty of information.

For recording purposes, if you run things through the Behr mixer before going to an interface and then a computer, you're just adding another (unecessary) step in the process, i.e. another source of noise, and the Behr mixers are very noisy to begin with in my experience .

so if i use the
"Behringer UCA202 U-Control Audio Interface"
will that work at all? and if so...

where do i put the RCA cables in the mixer and the interface?

You need an RCA (L/R) to 1/8" phone plug cable. Can get from most local electronics stores or Radio Shack. Connect RCA cables to the Tape Out on the mixer as mentioned by apstrong's post. The 1/8" plug connects to the soundcard line in. Standard sound card may not result in the best quality but it will work. You should download ASIO4all driver (free). This driver will help reduce latency during recording and give you ability to adjust buffers for better A/D performance.

I would go for the Maudio, RME, EMU, Presonus, Tascam products if you want to upgrade. USB 2.0 interface with 2-4 channels would be good.

for lots of good info.

I'm going to go back a step. Why do you want a mixer?

"Why do you want a mixer?"
Because all pro recording studios have them and thus I must have one too.

Seems to be the common misconception when connecting one mic... but so far we don't know what he's connecting.

If OP is actually just plugging a single mic in, there are better options. For actual mixing of various things, fine.

Why bother with the mess of trying to figure all of that out? Save a few bucks and buy a simple interface that will suite your needs. Codemonkey is right...Seems people see a mixer in the studio and think that it is an essential part of recording equipment even for the home recorder.

As others said...if you only want to record one track at once, you would be better of investing in a much better sound card, with maybe even a built-in preamp for your microphone, just to keep it all in one box.

Now, if you want to record a few different mics at once, all this mixer is gonna do is summing all the inputs to just the one stereo/mono track. This is fine only if you know what you're doing regarding having all the levels on the mixer to the right settings.

What are you exactly trying to do with that mixer?
