Cell phone breakout box?

Cell phone breakout box?

I have a Skype interview in which I need to record only the person in my booth, not the other end of the call.

Without an available computer and interface, I'm left with a cell phone.

So far, the setup is like this:

A/V breakout cable mini plug into the phone
L&R from phone to the board (for monitoring)
Mic into the board.
Aux send from board (balanced) through a D.I. to the mic input on the A/V cable

I'm recording the microphone input to the board only.

For the person on my end of the call, they hear their voice very clearly (since they're hearing the mic) as well as the other person's voice. But my person's voice is a little distorted on their end. Not a lot, but enough to annoy me.

Obviously, I'm overloading the mic input. I can't find an operating level for that mic, though. I assume it's like a computer (mini-jack) mic that gets 5V to power the capsule.

Does anyone know a box that'll do what I'm trying to do, or a schematic for a level/voltage fix for the mic input? I can build stuff and have lots of parts, I just don't know what to do exactly.

Or am I screwed?

Thanks in advance

Chances are excellent that JK Audio makes the interface that you need.

OTOH, I would think there would be enough computers in Denver that you could lay your hands on at least one.

Thank you Richard!

They have lots of options that should do the trick.
