8 Audio Authority Model 1173BK User Manual
Source Mode Installation
In this mode the unswitched audio channels of the six AVAtrix system A/V sources
are provided as inputs to the audio distribution system. The Model 1173BK is there-
fore not associated with any one Model 1176BK, so only one 1173BK is necessary
even when there are multiple 1176BKs in the system as shown in the table.
The AVM-562 architecture allows up to five expanders. Using Source Mode, the
maximum number of Cat 5 zone outputs is 30 (shown) with one 1173BK installed.
1. Install the Model 1173BK anywhere in the AVAtrix stack and set its address dial
to the “M” position.
2. Connect the desired audio outputs, which represent the six AVAtrix A/V sources, to audio input channels on the audio
distribution system.
3. Audio system infrared outputs, if present, are intended to control its input sources. Plug a stick-on IR emitter into
each of the audio system’s IR output jacks and apply the emitter to the corresponding A/V source. In this way, source
control commands originating in each room are routed by the audio system via infrared to the relevant source. See
below for more information about using RF control systems.
IR Signal Routing
In Source Mode, the A/V sources and zone volume are generally controlled via IR through the audio distribution system
keypad / IR receiver in each zone. The AVAtrix IR commands must be routed through a separate IR receiver connected
to the AVAtrix Cat 5 receiver, necessitating two IR receivers in rooms with both A/V Cat 5 receivers and distributed audio
service. To program IR remotes, download AVAtrix IR codes from www.audioauthority.com/page/software or obtain the
codes from your remote control manufacturer. The AVAtrix may be used with any of five Cat 5 receiver styles. Models
9878 and 9879 and 9880 dual Cat 5 receivers feature an IR pathway and analog audio, and 1180R and 1180RD do not.
Using RF Control Systems
If desired, use the RS-232 connection for source switching and volume control, utilizing the 1173BK ExpressRamp volume
control (see page 10). The RF base station should generally be located near the AVAtrix. It may be to advantage to use
Model 1111 to inject IR commands from the RF base station zone outputs into the Cat 5 pathways to simplify program-
ming. See Model 1111 manual for details.
Source Mode User Instructions
Depending on the installation, you will use a wall-mounted controller or an infrared or wireless controller to select which
music from various audio-only or audio/video sources you wish to enjoy. Your installer will have connected the AVAtrix
system and your whole-house or room audio system to work together, enabling you to bring the pictures and sound you
desire to each location in your home.
