Question:  I am an audio engineer for a small college theater. I need a productthat can link the output of my console with the Clear-com headset. Basically, I want to be able to cue audio on the console and hear it inmy headset as well as hear cues from the stage manager in my headset atthe same time. Right now, I'm using an old PI junction box that iscausing problems with our new Clear-com system. Is there a simple adapteror something to do this?
Answer:  Our RS-602 beltpack does provide a the ability to accept a balanced Program input locally at the BP.the input is only is mono feed
Or you could look at using a MS-702 / 704 main station which again will allow you to inject mono program audio locally to the main station  
Our AB-120 might be able to do what you need but again it only has Mono inputs for program not stereo and is probably quite a bit more expensive.
