Abus MDADZHMS Installation Manual - page 5
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.
Infrared (IR) Emitter Port [8]
– This will accept a standard IR
emitter with a 3.5mm 2-cond. mini plug. This jack is provided
for infrared control of the source component. It is a routed
output that will only emit commands from a Volume Control
Module in a zone that has selected that source. Some
components have a 2-cond. IR input jack on the back. It is
recommended that this direct connection be used.
CAUTION: Do not confuse a serial data port connection
with an infrared port.
12v DC Trigger [12]
- This is a 12v DC output that turns on
when that source is selected. The output can be used to trigger
a relay for power control of the source component.
CAUTION: Do not hook up devices to the Trigger that will
exceed 100mA of current draw.
Audio Input [13]
- For connection to source component
Loop Out [14]
- To loop the same audio component source into a home theater receiver or an amplifier
The A-BUS Multi-Source Audio System allows for up to four sources to be heard in up to sixteen zones simultaneously.
