General Information
The Model 1173BK Multi-Zone Audio Router with Volume Control is a companion
product to the AVAtrix™ HD Cat 5 Routing System. It provides six analog or digital
audio source outputs to a distributed audio system to enable coordination of a room’s
audio program with the video program being received on a Cat 5 zone receiver. The
1173BK responds to IR or RS-232 commands from programmable control systems to
attenuate volume levels on individual analog outputs.
Key Features
• Independently adjusts volume from 0 to -78dB in each zone (analog only)
• Maximum configuration is six sources on 18 AVAtrix zones (Tracking Mode), or six
sources on 30 zones (Source Mode)
• IR routing for volume control and source control signals from zones
•
ExpressRamp™

Installation
These instructions address the Model 1173BK, which is always used with an
AVAtrix™ system. The system must include either a Model AVM-562 or Model
AVX-562 with Cat 5 zone receivers, and can also include up to four Model 1176BK
matrix expanders. Refer to the AVAtrix instruction manual for complete installation
and setup directions.
* ExpressRamp
™ enables a smooth volume change from the current level to a pre-defined level using a
single RS-232 command. It streamlines the programming of audio “scenes” on control systems and avoids
abrupt volume changes. ExpressRamp is not available using IR commands. See page 10 for details.
