Enabling easy integration of whole-house audio into an AVAtrix™ Cat 5 Matrix system, the 1173BK is a perfect complement to projects involving distributed audio. The Multi-Zone Audio Router's selectable "source" and "tracking" modes support a variety of whole-house audio configurations. Its volume control and source switching capabilities enable simple integration with a zone amplifier. See detailed application diagrams here.
When using traditional zone amplifiers without onboard volume control or switching, the 1173BK should be operated in Tracking Mode. The audio output from the source currently selected in a zone is routed to the corresponding audio output on the 1173BK. (Example: Zone 2 is viewing Source 4 - the 1173BK would output Source 4 audio from Output 2). The output is then connected to a separate amplifier used to drive speakers in each zone. This mode allows audio to be switched in sync with the video source being viewed in each zone.
When using amplifiers with their own volume control and signal processing, the 1173BK should be operated in Source Mode. The audio output from the each source is looped to the corresponding audio output on the 1173BK. (Example: Source 1 audio is replicated on 1173BK's Output 1). Audio remains live at each in-room Cat 5 receiver, while also interfacing to a third party whole house audio control system or multi-channel amplifier for processing, amplification, and room selection.
