Welcome to A-BUS
AUDZBX75
A-BUS Source Input Module
Installation Manual
We hope you enjoy your A-BUS system. This AUDZBX75 Source
Input Module is designed to connect to the MDADZHMS A-BUS
Multi-Source Audio Hub, which is the core of your A-BUS system.
The MDADZHMS Multi-Source Audio Hub will accept up to four
AUDZBX75 Source Input Modules to connect the Hub to a
maximum of four source components. It also repeats infrared (IR)
commands to the source components. The AUDZBX75 Source
Input Module is activated by commands sent from the AUDZ45
A-BUS Multi-Source Volume Control Module. See the Installation
Manual for the MDADZHMS Multi-Source Audio Hub and AUDZ45
Multi-Source Volume Control for full system instructions.

AUDZBX75 A-BUS Source Input Module
Installation
– Instal the AUDZBX75 Source Input Module wherever it is desired to locate an audio
source component that will be used as an input to the A-BUS Multi-Source Audio System. Typically,
Source Input Modules are located in the entertainment center, family room, kitchen, master
bedroom, office or utility area or other areas where computers, cable boxes, satellite receivers,
media bridges and/or televisions are located. It is best to locate the actual module in a single-gang
box near, but not directly adjacent to, a power receptacle. The AUDZBX75 Source Input Module
may be located up to 100ft (30m) away from the MDADZHMS Hub. The A-BUS System uses Cat
5/5e wiring following the TIA 568A color code (see A-BUS Wiring Color Code).
Input Level Adjustments
– On the back of the AUDZBX75 [7] Source Input Module are Left and Right
Input Level Adjustments. Normally these are set to the full clockwise position. Turn each control
counterclockwise to reduce the input level to match the volume level of the lowest source in the system.
Repeat this procedure for any other sources that are too loud, until all sources are balanced. Some
audio sources such as computer sound cards may have very low output. In these cases it is recom-
mended that the volume be turned up at the output of the source. Check for either a physical volume
control or an IR remote volume control on such devices.
Status Indicator [3]
- The green status light indicates when the system is turned on. The system is
activated when the Hub receives a source-select command from any zone. Other zones may be
activated at any time. Individual Volume Control Modules may have to be turned on separately before
sound can be heard.
Infrared Talkback Indicator [3b]
- The Red Talkback indicator flashes when an infrared data
command is passing through the Hub.
