Warranty
Please contact your place of purchase for warranty information.
The A-BUS ABX-88 4 source 4 zone (x2) Multi-Source Hub with expansion
Audio input [1] [2]
- There are four stereo line-level source inputs [2]. Each
input has individual level adjustments [1] (left and right).
Trigger [3]
- The trigger is activated when any part of the system is on; its
output is 12 volts at 300 mA.
Emitter Ports [5] [6]
- Each source input has its routed emitter port [5], if
more than one component of the same type is used the Remote Control
commands will not be confused. Eg. Two tuners. There is also a common
emitter port [7] to control components that are common to all zones.
Indicators [4] [6] [10]
- The green status indicator [4] is on when the system
(one zone or all zones) is in operation. The red emitter indicator [6] flashes
when there is an infrared data command passing through the Hub. The
power indicators [10] indicate when the corresponding power supply is on.
A-BUS Outputs [8 A & B]
- Each of the A-BUS Outputs provides the power,
audio and data signals to feed a room unit. There are four output zones;
each zone may independently select from any of the four sources. Each
zone has two outputs, bank ‘A’ and bank ‘B’. One power supply is supplied
with the Hub to power the outputs for bank A. A second power supply can be
added to power the bank B or alternatively the second output can used as
an expansion port to feed one or more single source Hubs with expansion
capability.
CAUTION:
Only an approved A-BUS 4-Room Power Supply [12] should be
used. Substitutes which may appear to be suitable are not recommended
and will void the warranty.
DC Power Input Sockets [12]
- There are two power sockets one for each
output bank ‘A’ and ‘B’.
ABX Control Ports (In/Out) [9]
- Another ABX-88 Multi-Zone hub may be
connected to this port if additional zones are desired. Up to four ABX-88
Multi-Source Hubs may be connected together, providing for a maximum of
16 zones.
CAUTION:
The ABX Control Ports pass the control data between Multi-
Source Hubs and may not be used for any other purpose.
Audio Outputs [11]
- The RCA Audio Outputs allow sharing of the audio
sources with the main system amplifier or to expand to additional ABX-88
Multi-Source Hub. The audio levels adjusted at the input will be the same on
the output so no level adjustment will be required on the additional Hub(s).
IR Remote Control [13]
- ABR-43 Learning Remote Keypad with Cradle.
Can be used as a handheld remote or on wall keypad. Built-in A-BUS
commands are incuded and additional keys have learning capability.
Please see separate instructions.

Setup
Input Level Adjustments [1]
- The ABX-88 Multi-Zone Hub is supplied with
the input level adjustments set fully clockwise. If one source is noticeably
louder than the other sources, turn both the Left and Right Input Level
Adjustments for that source counterclockwise, reducing the input level to
match the volume level of the lowest source. 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 recommended 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.
Trigger Output [3]
- The Trigger Output may be used to activate a relay or
other device that responds to a steady-state 12volt trigger signal. This output
may be used to power a Power Strip, which may be used to power the
source components. When the System Mute command is pressed, the 12
Volt Trigger Output will be inoperative. Source components that are plugged
into a trigger-controlled power strip will be switched off. Care should be
taken to ensure that components will not lose their memories (clocks, etc. or
presets) after long periods of non-use.
Infrared (IR) Emitter Ports [5] [7]
- There are 5 emitter ports, 4 are routed
ports. The routed outputs will only emit commands from a zone that has
selected that source. This will allow more than one source device with the
same code set to be used. If this is the case, light-blocking emitter caps
should be used to prevent infrared commands from straying into the infrared
receivers of adjacent components. The common emitter port will generate all
commands from any zone with infrared capability. Some components have
an IR IN socket 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.
TIP:
1. Finding the infrared receiver location in some components can be
difficult. To find the right place, place a large card with a hole the size of a
folder punch hole in it over the front of the component and while generating
a command from the components Remote Control handset move the card
around until the unit responds to the command.
2. In situations where the unit is not responding to the commands from the
emitter or if the response is erratic the signal level may be too high. If the
operation improves when the emitter is held away from the component a
filter will be required such as some exposed camera film.
3. Some source components may not respond to repeated infrared
commands. This is rare and may require a change in component
Status [4]
- 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. Once a command has been received by the Hub to activate,
a 12 volt signal will be available at the Trigger Output [3]. Other zones
may be activated at any time. Individual Volume Control Modules have to
be turned on separately before sound can be heard. Regardless of which
Volume Control Modules are on or muted, the 12 volt trigger will remain
active until a System Mute command is sent to the Hub.
Infrared Talkback [6]
- The Red Talkback indicator flashes when an infrared
data command is passing through the Hub.
Power [12]
- The two red power lights indicate when the power supplies
connected to bank A or bank B are active. These indicators do not indicate
the system is active (see System Indicator [4]).
