Hi Thanks for the reply,

That's what I was afraid of, The person who was helping me with setting this up, said no problem it would work, The balance control won't work, what if you want both on at different levels or to mute one? I was originally looking at the Audio Authority SF-16M for this, spoke with there tech support and they said it would work, but now I see they have discontinued that line (although I can still get one), so I up in the air which way to go,

The cost of the swamps vs what I am using them for is the issue. The system we are installing are ceiling speakers for radio communication around a firehouse. Basically 2 or 3 speaker in each room with different two way radio sources.

any suggestions?
