• Connect associated equipment (see detailed instructions in the AVAtrix Manual). • Connect the product to a suitable power outlet using only the power supply furnished. • Update AVAtrix firmware to v1.4 or greater. General Information The Model 1173BK Multi-Zone Audio Router with Volume Control is a companion product to the AVAtrix™ HD Cat 5 Routing System.
The 1173BK provides an audio breakout point to connect AVAtrix source audio to audio distribution equipment that accepts stereo analog audio (for digital audio, see page 7). The analog outputs are volume controlled via commands transmitted through the AVAtrix IR inputs or the RS-232 port.
Tracking Mode Diagram 1: Multi-Zone Amplifier Tracking Mode is used with audio distribution systems having dedicated amplifiers for each room’s speakers. The amps may be dedicated A/V receivers (see page 10) or a multi-zone amp, as shown below. The 1173BK audio output #1 tracks with the AVAtrix Cat 5 output #1 so that the audio always matches the video at the zone. Address each 1173BK to match the AVAtrix outputs (see page 4).
Tracking Mode Diagram 2: A/V Receivers as Zone Amplifiers In this configuration dedicated A/V receivers are used in place of a multi-zone amp. Here the 1173BK performs volume control, whereas in diagram 3 IR signals are routed to each AVR to control volume. The 1173BK audio output #1 tracks with the AVAtrix Cat 5 output #1 so that the audio always matches the video at the zone. Address each 1173BK to match the AVAtrix outputs (see page 4).
Tracking Mode Diagram 3: Digital AVRs as Zone Amplifiers with Volume Control In this configuration dedicated AVRs are used. Analog or digital audio may be connected from the 1173BK to the AVR inputs. Digital output may be either 5.1 surround sound (e.g. zone 1 below), or two channel PCM (e.g. zone 3). IR signals from each zone are routed to that zone’s AVR to control volume. The 1173BK audio output #1 tracks with the AVAtrix Cat 5 output #1 so that the audio always matches the video at the zone.
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 therefore 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.
Source Mode Diagram Integrated Audio Distribution System Source mode is used with a whole-house audio system that includes its own switching and volume control. The 1173BK audio output #1 always provides the audio from Source 1. 1173BK volume control is not generally used with this type of system.
RS-232 (Serial) Extended Command Set All valid commands receive a response, and all changes in the AVAtrix system via any method are reported. In the “Command” column on the next page, actual commands are shown in upper case, and parameters are represented by lower case bold characters (commands are not case-sensitive). All commands must be surrounded by brackets [ and ]. Command Definitions (Extended) Command: String received by the AVAtrix from the controlling hardware.
Query Commands (Extended) Query: Response: Description: [?,C,Rx,On] (Rx,On,Im) Query zone connection [?,R,Rx,On] (Rx,On,R,V,t) Query zone restriction status.
