Please help point me in the right direction based on the below scenario.
My boss has just moved into a house that has in-ceiling speakers installed in a number of rooms. The speaker wires are all terminated in the lounge and are not accessible from the rooms. There is no current amplification. He has a Sonus device and wants to be able to control the volume levels in each room individually. Other than purchasing additional Sonus devices for each zone, what are the options available. He's wanting to keep the costs down and is open to second hand equipment if available.
