I'm having a trouble distributing my headphone mixes and was after some advice. I'm currently using a crappy Behringer powerplay 4 channel amplifier and deriving my mixes from the aux sends on our Trident.
Headphones are DT 100's, but we are just not getting enough volume to the cans and are subsequently having to drive the aux sends to get enough level out of them. I don't really know enough about ohm'ages etc, but can anyone suggest : either a way to make what we have work, or a better matched haedhone amp. The one thing i do like about the power play is that you can mix a main, or one of 4 aux inputs, to create a blend for different performers. And i really need 4 or more seperate sends. Ideally i'd have one of those individual mixer systems, but again i don't know much about those either.

HELP ME OH ORACLES!

I have one of those powerplay headphone amps too and I don't have trouble getting volume to the headphones. Maybe you need headphones with a lower ohm rating? I know my AKG K240M headphones are about half as loud as some of the other sets of phones I have, I believe AKG makes a low-ohm version of those now.

Yeah, dre's probably right about that. AKG makes the same model headphones in different impedance ratings so you need to check the specs carefully.

I use a Rolls RA62 and never had a problem driving any style headphone with it, but of course, it's has less features than a mixer that can send unique mixes to different locations.

I forget who it is now (Axiom?) but someone was making a headphone distribution system that sends audio over telephone wire to little digital mixers at each station. Each performer can create their own unique mixes and then store them.

Impedance. That's the word I was looking for. Darn it.
