Turning iPhone jack into RCA Audio IN/OUT Jacks

Anyone know of a plug that would split out the iPhone's headphone/mic jack into an RCA audio IN and OUT jack so I could connect a professional microphone and headphones?

So I guess I need a breakout cable that has TRRS plug -> mono RCA IN and Stereo RCA OUT. Or TRRS plug -> Stereo female minijack & mono female minijack

8-Core 3.0GHz (late 2008), 16GB, 5TB, Nvidia 8800, Mac OS X (10.6.1)

Here's the adapters necessary to make it happen.

The red lead is the mic lead. Now you're in business. You can convert that RCA to an XLR connector and now you're REALLY in business.

Keep in mind the iPhone DOES NOT HAVE the ability to vary the input level, so you'll want some kind of sound mixer between the iPhone and the mic.

I use this (battery powered and lots of mixing options)

No obvious 3rd party products to do what you want. So, you're looking at a hack job, I expect.

Some users have reported that the AV cable from their digital camera/camcorder provided that functionality. Will depend on the pinouts of the AV cable, and may take some trial and error with the RCA plugs. Here's what worked for someone:

White/Black: Audio out (L)
Yellow: Audio Out (R)
Red: Mic level input

You could also use something like THIS and splice the mic cable to an RCA cable.

Looks like there may be more advice here:
