YOU NEED THIS
This type of monitoring is not new, what is new is the price, Behringer has brought the capability of MUCH more expensive systems down to the working man, thank you ULI!
We replaced a rather sophisticated analogue mixing system that gave us the similar capability, each person in the band had their own mix, it took a lot of wire and connections to get all those mixers connected.
The first day we got the system I had to do a lot of running around and explaining and helping others learn to mix their own monitor, by the end of the first session everyone was smiling ear to ear because they could finally really hear and tweak the mix the way they want it.
Now the monolith of monitor mixing stuff we've been using is leaving our studio because this little digital Behringer system does everything the former system did and more. We're using it with Carvin stereo in-ear monitors and there is plenty of volume.
This rack mount interface is pretty simple and easy to set up. I put a Behringer patchbay in right above it so it's easy to jack sources into the headphone system. There seems to be plenty of headroom, every channel has signal present and clip indication, it's easy to keep an eye on the system. So far I've never heard it distort or do anything weird.
Thanks Sweetwater, we love it!
