I have just wasted my time making a breakout cable/box built from an old TRRS component video camera cable, a project box, and 2 panel mount jacks. I wanted the jacks housed inside a box so they would be a little more sturdy, also because I read somewhere that I might need to place a capacitor in line to block the dc current, and I wanted to hide it in the box.
The 3.5mm stereo headphone jack works great, but the 1/4" mono mic input jack does not.
There is no capacitor in line yet... I wanted to make sure it worked before I got worried about current flowing to my mics.
I have tried using a vocal mic(sm58), instrument mic(sm57), and a computer mic just to see if I got any signal. Nothing. Is there a reason only electret mics work in the 4 conductor jack? Is there any other 4 conductor cable that WOULD work?
Everything should be wired properly... Option B is to buy a 30 pin breakout board and solder the cables onto the board.
Would this work?
If I did this, it seems like I would have more options at hand.
I would like to have 2 separate volume controls: one for the headphones and one for the mic/line input level. What components would I need for this?
Any help at all would be much appreciated.
I own an Ipod Touch 2nd gen and an Ipod Nano 2nd gen.
And I have tried using "voice memos" and griffin's "italk" app.
