Audio Authority 1173BK

AVAtrix Multi-Zone Audio Router w/ Volume Control

Audio Authority 1173BK AVAtrix Multi-Zone Audio Router w/ Volume Control

Audio Authority 1173BK Audio Interface for AVAtrix Systems

This Audio Authority 1173BK MultiDriver makes it easy to create a distributed audio system that works in harmony with the AVAtrix. Featuring source switching, volume control and IR routing, the 1173BK supports a variety of whole-house audio configurations for maximum installation versatility.

Designed to stack in an elegant manner with other AVAtrix system components, the 1173BK  provides an interface between AVAtrix systems and whole-house distributed audio systems from other manufacturers, or use with Audio Authority's own SF-16M 16-Channel zone amplifier.

The 1173BK contains all the 1172BK’s features, but adds analog audio volume control per output, allowing attenuation from 0 to -78dB.  This allows the AVAtrix to provide volume control and switching for a distributed audio system.  AVAtrix customers just need to add an amplifier or A/V receiver and they have a complete home distributed A/V solution!

When used in Source Mode, the audio outputs mirror the AVAtrix source inputs, while Tracking Mode mirrors the audio source selected by each corresponding remote wallplate.  In addition, the 1173BK routes IR signals to the appropriate source or zone amplifier.

Like most Audio Authority products, the Model 1173BK comes with a one year limited warranty from the manufacturer.

Audio Authority's Description

AVAtrix Multi-Zone Audio Router w/ Volume Control

Model 1173BK


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. [links to AAC site]

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.
