    Product specification sheet for the Channel Vision AB-904 4-Source, 4-Zone A-BUS whole-house audio kit.

    Overview

    The Channel Vision AB-904 is a 4-Source, 4-Room A-BUS Kit — an excellent whole-house music solution. It allows up to four different audio sources to be played in four different zones simultaneously, ideal for families with a variety of listening interests. Control is simple thanks to the P-1044's source-specific IR repeating, which allows independent control of identical source components. The included A0505 remote lets you adjust the AB-134 volume level without leaving your favorite chair.
