Im trying to connect my computer to a mixer board. When I connect it to the mixer from PC i get a very bad sound (sounds distorted or some sort).

Bad sound diagram:

(PC headphone) --> 3.5mm cable --> 1/4 Adapter --> Mixer Line in (neutrik xlr trs combo)

Am I doing this wrongly? Or should I even

  • What brand / type Mixer? What brand / type sound card ? – Edwin van Mierlo Oct 24 '18 at 4:00
  • Can you also explain what you mean by distorted - do you mean like an overdriven guitar amp? – Rory Alsop Oct 24 '18 at 16:16
  • Dont have an tape input because it a usb external soundcard (headphone + mic). – user1148967 Oct 25 '18 at 17:09
  • Are you saying you’re trying to record audio from your computer back into your computer? Is your 1/4” end a TRS or just TS? – Timinycricket Oct 26 '18 at 2:21

yeah you're doing it wrong.

The PC headphone output is a stereo output jack. pinout is :

  • Tip: Left
  • Ring: Right
  • Sleeve: Ground.

In order to connect this to a computer, you need to make an adapter cable.

you will need two XLR's or 1/4 inch adapters.

1/4" adapter or XLR Adapter 1 (Left) will require the following pinout:

  • Pin 1 (ground) (Sleeve)
  • Pin 2 (Left Signal) (Tip)
  • Pin 3 (ground) (Ring)

1/4" adapter or XLR Adapter 2 (Right) will require the following pinout:

  • Pin 1 (ground) (Sleeve)
  • Pin 2 (Right Signal) (Tip)
  • Pin 3 (ground) (Ring)

What you are currently doing (wrong) is connecting the stereo signal directly to the XLR input:

  • pin 1 (ground)
  • pin 2 (left)
  • pin 3 (right).

Because the input is balanced, the signal you are experiencing on the input is actually "L-R" which is the stereo 'difference' signal.
