I have a IK Multimedia iRig Mic that I want to plug into a standard TS 1/8 inch mono microphone connector (such as a computer).

The iRig mic has a iPhone 1/8 in connector (4 way), which transfers in and out of the iPhone.

How can I connect the iRig to a mono input? I have tried just plug-in it directly, with no success.

  • Keep in mind that the Apple audio input ports are line-level, and PCs generally use SoundBlaster-style plug-in power TRS ports. So you need to find out what level the iRig outputs and then figure out how to match it with your mac or PC. Sep 11, 2012 at 0:45
  • I also tried connecting it on a mixer microphone input (and adjusting the levels) and line input, without success.

  • you might try using some alligator clips to try connecting the tip and various rings to the tip and ring on a 3.5mm or 1/4" cable. If you can't find a schematic, you might be able to figure out the signals that way. Sep 11, 2012 at 3:08

I picked up a Smartphone Headset To PC Adapter and it works with an iRig. Here's one on amazon:



I found the Apple connector has the microphone signal on the sleeve ring and second ring. That explain why it does not work out of the box.

I can't find any adapter on the market for that. However it seems relatively easy to:

  • cut the wire before the existing connector
  • install a TS 1/8 mono male connector on the microphone end
  • install a TS 1/8 mono female connector on the existing connector end

That way, I will still be able to use the iRig mic on a iPhone by using the existing connector, and also plug the microphone on any 1/8 mono input by using the TS 1/8 mono male connector I installed.
