This was exactly what I need for restaurant/pub I manage. Having the ability to split sound in and out of any room (zone) is perfect. We were looking at devices that cost thousands of dollars. This does exactly what I need for just a few hundred bucks. We eliminated a complex mixing board like a rock band would use. This is so simple. The little switches are not the easiest thing in the world to use, but they get it done. Every member of my staff understands how to use it and adjust it. We are talking about a wide range of intellect and yet they can learn how to use it very easily. Combined with a set of good cordless microphones, the possibilities are endless. I can zone a microphone into any room I choose. This is the best answer to anyone with a bar or restaurant with multiple rooms.
