As far as range goes, what I mean is the distance from the VOICE to the INTERCOM, not from intercom to intercom. For example, I can now get commands to work from about 2' when using my microphone, but if I move more than a couple feet from the mic, its a no go. I was thinking I might have the same problem with an intercom setup. I would like the intercoms to be at least 10-15' away and still be effective if possible.
So how quiet does the room need to be? Maybe I am missing something, but if you have to mute the audio...how practical is a setup like this? I thought the hope was to have hands free control, but if I have to reach for the remote to control the volume, I may as well just control the lights with the remote. Sure there are a lot of times when the room is quiet, but 90% of the time I either have music from the HTPC going, radio, or TV.
