The Behringer is sitting in the back of the den, underneath the Bryston. It works perfectly EXCEPT for the RTA section, which died a couple years ago. Don't know if its a soft switch problem, software or connection, but having it would be nice. Not worth the money it would take to repair.
The dbx also includes its own calibrated RTA and mic. To use it, full range signal has to be routed from the dbx to amps and spkrs. Since I run the panels straight from the preamp, I don't get full range pink noise when I push the RTA button. The RTA analysis function in the dbx doesnt work with an external pink noise source.
So I thought I'd start with the phone. Now, if anyone has a working, calibrated RTA unit, I would be v interested in borrowing for an hour or so.
