Okay, so here's the issue:
I have 2 inputs on my X-Station 25. I want to route each one to a mic, for a total of 2 mics. Each mic will be a seperate person, in a seperate room. Of course, each person will be wearing headphones. So I'll need a headphone amp connected to my headphone output. I'll want some headphones too, just in case the monitors are too loud and picked up by the mics (this is a portable setup, so the surroundings will vary).
What I want, is the headphone amp input connected to the headphone out on my audio interface, and I also want a mic input on the headphobne amp, connected to a cheap mic that I have. And I want the headphone amp to mix the signals together, so the headphones hear my my mic and the output of the audio interface. This way I can talk to the vocalists thru my mic, they hear me in the headphones, and I'm not wasting an input on my audio interface (and my mic isn't being recorded).
Is there anything like this on the market? I'd rather have it all in 1 small box as this is a portable setup. So I would rather not get a small mixer and a seperate headphone amp.
