I'm pretty new to recording and I just picked up a vintage "transistorized stereo mike mixer" from a flea market. The guy said it worked perfectly and I could hook it up to my computer with the right cords. Here's some pictures of the thing enter image description here

Would a left and right audio to usb cord do the trick? I'm looking to use this with Reaper, by the way.

Thank you!

Generally speaking mixers used for live sound are too noisy to use for recording applications. So, technically, 'yes' you could hook it up, but realistically, it wont make a very nice noise.

The sound quality would be made even worse if you tried to plug the mixer directly into a mic socket on a PC/laptop as the mic socket will try to amplify the signal (unless it is specifically a line level input - if it's got a picture of a mic, its a mic input, not a line input).

Be careful using USB sound adaptors as they tend to be 16bit rather than 24bit that most audio devices work at - this will further reduce the quality of the signal.

You're best bet would be to get a proper dedicated audio device, you can pick a new one with two mic/line inputs for around £100.

  • Alright thank you. That's very sound advice. I just picked this thing up for $4, so it's not much of loss :P Commented Jul 19, 2016 at 21:10

Yes, you can. You'll need a stereo RCA to 1/8" adapter like this.

And then connect the 1/8" into the line input on your computer's sound card.

  • Thank you, but I'm using my laptop, which only had a headphone jack. Am I just out of luck now? EDIT: Okay, it might function as both. I'll play around with it in a moment Commented Jul 11, 2016 at 3:06
  • Yeah, it seems like that's not gonna work :c Commented Jul 11, 2016 at 4:19

    That's too bad. I tried to find a cheap USB sound adapter but all the ones I found only had a mic input and no line input. If you want to keep looking around you might be able to find one. But IMO, a better option would be to simply get a USB audio interface with built in mic preamps. How much did you get that mic mixer for? You might be able to return/sell the mixer you got. There are many 2 channel units in the $99 range like the Mackie Onyx Blackjack. This will give you significantly better sound quality.

  • @Tekkerue Just picked up an Onyx Blackjack and it's a solid interface for the price. Commented Jul 12, 2016 at 1:47
