SECTION 6.0: EXPANDING THE SYSTEM (Combining 2 BXAUDIO Controllers)
The BXAUDIO4X4 System can be expanded to up to eight-zones by linking two Controllers together with the
included Expansion ‘Null-Modem’ Cable (Xantech PN#05913560).
Expansion Procedure:
When expanded the system the following steps must be taken in the following order:
included Expansion ‘Null-Modem’ Cable (Xantech PN#05913560).
Expansion Procedure:
When expanded the system the following steps must be taken in the following order:
1. Wiring the System (See Expanded Wiring Connections) Note: Do not connect the Expansion cable until
after the Master Unit is programmed.
2. Enable Expansion Mode on both the ‘Master’ and ‘Slave’ unit.
3. Program the Master Unit as in Section 5.0
4. Copy (Clone) the Master Unit to the Slave Unit.
3. Program the Master Unit as in Section 5.0
4. Copy (Clone) the Master Unit to the Slave Unit.
Additional Components Needed:
1. Xantech Model AV61 Audio/Video Six Way Distribution Amplifier. (Sold Separately) - This device
allows the single A/V outputs of source components to be ‘actively’ split to the inputs of both
BXAUDIO4X4 Controllers. System requirement: 1 per source. Note: Basic AUDIO RCA ‘Y’ Jacks may
be used in-place of the AV61 Distribution Amplifiers if a passive audio splitter is acceptable.

2. Xantech Model 283TP Emitter ‘Combiner’. (Sold Separately) - This emitter is a single ‘Mouse’ Emitter
with two diode-isolated 3.5mm plugs combining the Emitter Outputs of each BXAUDIO4X4 Controller
Source Emitter Ports. System Requirement: 1 per source. Note: The 283TP Emitters will replace the
283M Emitters that come with the system.

EXPANDED WIRING CONNECTIONS
The Application Diagram, Figure 24, shows two BXAUDIO4X4 Controllers being used in a four-source, eight-
zone system. Each of the source components, XDT Dual Tuner, SAT, CD have their A/V outputs running
through an Audio Y-Cable to the Audio inputs on the two BXAUDIO4X4 Controllers. In this configuration, any
one of the eight zones in the system can select and monitor any of the four sources program material. Note:
AV61 Distribution Amplifier should be used if any loss or degradation in Audio signal is noticed.
Audio Connections
1. Connect the single-end of the Audio Y-Cable to the Left and Right output of Source 1.
2. Connect one of the Stereo Pairs of the ‘Y’ cable to the Source 1(Left and Right) Input RCA Jacks of the
2. Connect one of the Stereo Pairs of the ‘Y’ cable to the Source 1(Left and Right) Input RCA Jacks of the
designated ‘MASTER’ BXAUDIO Controller.
3. Connect the remaining end of the ‘Y’ cable to the Source 1 (Left and Right) Input RCA Jacks of the
designated ‘SLAVE’ BXAUDIO Controller
Combining IR Outputs
1. Using the 283TP Emitter, connect one of the 3.5mm Mono Mini plugs to the Source 1 Emitter Port of
one of the BXAUDIO8X8 Controllers.
2. Connect the remaining 3.5mm Mono Mini plug into the Source 1 Emitter Port of the other BXAUDIO
Controller.
3. Connect the Mouse Emitter end of the 283TP Emitter to the IR Sensor of the device connected to the
Source 1 Audio input.
4. Repeat for Sources 2 through 4.
Connecting the BXAUDIO Controllers
Note: The following is to be done ‘after’ the MASTER unit is programmed.
1. Connect one end of the DB9 Expansion Cable to the rear DB9 connector on one of the BXAUDIO
1. Connect one end of the DB9 Expansion Cable to the rear DB9 connector on one of the BXAUDIO
Controllers.
2. Connect the other end of the DB9 Expansion Cable to the rear DB9 connector of the remaining
BXAUDIO Controller.
