I have a whole house sound system using ChannelVision components for the sound distribution. The system stopped working last month and I think it may be the AB-202 unit. When searching on the web, I find AB-202 and AB-203 units available. Are they interchangeable in my distribution system. My existing AB-202 feeds two AB-1014 distribution units and then eight speaker sets with AB-114 volume controls.
Is there any advantage of replacing the AB-202 with the AB-203 unit?
