OPERATION – OUT-OF-THE-BOX 
The Controller/Amplifier Out-of-the-Box feature will verify that all sources and zone components are working 
properly to select and distribute audio prior to XPS™ IR programming. XPS™ Programming for specific 
components and features follows. 
 

1.  Connect BXAUDIO4X4 Controller/Amplifier as shown in Figure 10 to: 

a) BXAUDIO4X4 

Keypads 

b) Speakers 

 

c)  AC Power  
d) Sources 
e) IR 

emitters 

2.  Press “Power On” button on the front of the BXAUDIO4X4 Controller/Amplifier (wait for front panel 

LEDs to stop flashing – should be less than 20 seconds). 

3.  Turn on all sources and press play on all source components. 
4.  Press “POWER” on the Zone 1 Keypad. 
5.  Select “SRC1” on the Zone 1 BXAUDIO4X4 Keypad.  

a)  Press “VOL+” on the Zone 1 Keypad. The Volume bar should move on the Keypad and the 

audio content of the source connected to the Source 1 inputs should be should be heard 
through the Zone 1 speakers. 

b)  Press “MUTE” on the Zone 1 Keypad. The Zone 1 speakers will mute. Press MUTE again and 

the speakers will un-mute. (Pressing VOL+ or VOL- will also un-mute the speakers). 

c)  Use the source 1original equipment remote and verify that all source functions operate when 

aiming the remote at the Zone 1 Keypad IR sensor. 

d)  Repeat above for all zones and sources. 

 
BXAUDIO4X4 CONTROLLER/AMPLIFIER PHYSICAL LOCATION AND MOUNTING 
When you mount the BXAUDIO4X4 Controller, you should plan its location carefully.  Pay close attention to 
each of the following factors: 
1.  The amplifier is convection cooled.  That is, it depends on the natural free flow of air up through the slot 

perforations in the bottom plate, over the internal heat dissipating fins, then out the top cover, for adequate 
cooling. 

2.  If mounted in an equipment cabinet or other confining location, allow at least 2 inches of space above the 

top cover.  Be sure there are large openings in the shelf below the unit and in the cabinet to allow the entry 
of cool air and the escape of warm air. 

3.  If the cabinet contains other heat generating components or you are using several BXAUDIO4X4's in a 

large multi-zone system, you will have to pay even closer attention to adequate ventilation. 

4.  Do not hesitate to use fans (quiet, boxer type), if necessary, to ensure a constant flow of air through the 

BXAUDIO4X4's and the other heat generating components. 

5.  When mounting in a 19" (483mm) rack, adding a single RU (Rack Unit) spacer above and below the 

BXAUDIO4X4 will improve convection in heavy use applications.  

 

[One Rack Unit size = 1-3/4" (44.5mm) in height]. 

6.  In multi-zone installations, you will have large bundles of wire and cable to accommodate audio, video and 

speaker connections.  Be sure to allow enough room for the leads and dress them in such a manner so as 
not to block airflow. 

7.  The BXAUDIO4X4 is designed for mounting on flat horizontal surfaces. When mounting into a 19" rack, use 

a rack shelf or drawer. 

8.  Do not remove chassis feet.  They are necessary to provide proper ventilation. 

NOTE:  You should consider some sort of rear support for rack mounted units when used in mobile 
applications or when located in seismically active areas. 

Expanded System: 
When using two BXAUDIO4X4 Controllers in Expanded mode, place Controllers on separate shelves or provide 

2-inches of space between Controllers for ventilation.
