can somone please clear this up. <"Got it...

I figured out that I can run signal into both the front and rear inputs on the headphone amp, so all I need to do is run out of the direct out on the board, without signal mixed into the mixers output.
Radio shack had a little red square momentary switch that is exactly what I was looking for for $2.99, with 2 prongs... gonna mount that on the front trim of the desk, facing me but to the right under the mouse. Snip some sheathing off a cheap mic cable, expose the wires, cut the black wire and run it into the switch, and instant talkback button, no monitor problems. Mount the cable under the desk too so as to not be seen or bother me.
I like it.>"

so, when i open up an old mic cable, ther is a red and a blue wire. Do i wire one color to one prong, and vice versa? Is it kinda like a through swithch, that will only allow the signal to pass when the button is pressed? here is the like to the button.

This actually should be in the Other equipment or Recording forums, but since it's probably not gonna end up with 50 posts I'll just do it here -

First, open up one of your mic connectors on the cable you're going to use and see which of the two wires goes to pin 2 (it's usually embossed near the terminal, on the inside body of the XLR connector) whichever color goes to pin 2 is the one you want to break with your momentary switch contacts.

Rather than messing up a mic cable, I'd more likely get a small project box from Rat Shack, big enough to mount a male and female XLR panel mount connector (one of each) and your switch - then, wire those connectors straight through except for pin 2, which would go through the switch contacts. Now, you can use ANY two mic cables so you can put the box wherever you want and change cable lengths as necessary... Steve
 
how bout this, buy one cable, and cut it in the middle. Solder both wires from one end to the one side of the button, and the other to the other one. would this make it so that when i pressed down the button, the mic would go through?

Here is a link to pin positioning for mic connectors -

http://www.rane.com/note110.html

Scroll down to fig.1, it shows which pins are what.

pin 1 is shield, so if you open the connector and find the shield, then the pin farthers away from that is pin 2. Even if you splice the cable, you'll need to open the connector to find out which color wire you need to interrupt with the switch.

The reason I suggested the little box is that you will likely need a place to mount the switch anyway, so why not make it both solid and flexible to use at the same time?

Again, pin numbers are marked inside the connector. Some XLR connectors even have them numbered next to the pins on the OUTSIDE of the connector. You'll need a small flashlight to see them though, most are just raised numbers the same color as the rest of the connector body... Steve
 
went to the shack today, and now i have a brand new talkback mic!

(followed knightfly's instructions and saved me a mic cable)

thanks
