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. – ObscureRobot Sep 11 '12 at 0:45
  • I also tried connecting it on a mixer microphone input (and adjusting the levels) and line input, without success. – decasteljau Sep 11 '12 at 1:43
  • 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. – ObscureRobot Sep 11 '12 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.
