ABUS-HUB4X8 Multi-Source Multi-Zone Hub
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 300mA.
Emitter Ports (5) (7) - Each source input has its routed emitter port (5) if more that one component of the same type is used the remote control commands
will not be confused. Eg. 2 tuners. There is also a common emitter port (70) to control components that are common to all zones.
Indicators (4) (6) (10) - The green status indicator (4) is on when the system (one 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.
ABUS Outputs (8 A & B) - Each of the ABUS Outputs provides the power, audio and data signals to feed a Volume Control Module. 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 one bank. A second power supply can be added to power the second bank or alternatively the second output can be
used as an expansion port to feed one or more single source hubs with expansion capability.
CAUTION: Only an approved ABUS 4-Room Power Supply (12) should be used. Substitutes which may appear to be suitable are not recommended and
could void warranty.
DC Power Input Sockets (13) - There are two power sockets one for each output bank “A” and “B”.
Data Expansion Ports (In/Out) (9) - Another ABUS-HUB4X8 may be connected to this port if additional zones are desired. Up to four ABUS-HUB4X8
Multi-Source Multi-Zone hubs may be connected together, providing for a maximum of 16 zones. CAUTION: The Data Expansion Ports pass the control
data between multi-source hubs and may not be used for any other purpose.
Note: The data expansion (9) and audio expansion (11) ports must be connected to additional hubs for proper function.
Expansion Ports (Audio) (11) - The RCA Expansion Outputs allow expansion of the audio sources to the main system amplifier or to an additional ABUS-
HUB4X8 Multi-Source Multi-Zone Hub. The audio levels adjusted at the input will be the same on the output so no level adjustments will be required on
the additional hubs).
IR Remote Control (14) - One ABUS ABO-41RC remote control handset is supplied with the ABUS-HUB4X8 Multi-Source Multi-Zone Hub. This remote
control includes a dedicated ABUS bank and includes keys for most standard functions including color cable box buttons (not used in all countries). The
remote control has a code library built in; however, it is capable of providing advanced functions for user convenience. All keys have learning capability
including the bank keys; all keys can also learn multiple commands (macros). See separate instructions.
ABUS-VC3 Keypad Volume Control Module
The ABUS-VC3 (RJ) Keypad Volume Control Module was designed to work with in-
telligent ABUS Multi-Source Multi-Zone Hubs using standard ABUS commands. The
ABUS-VC3 provides the following function:
Volume Up/Down
Input Selection Up/Down
Room Off
System Off
Infrared repeating
Status indication
Infrared talkback
Volume level change identification
IR Remote Control ABO-41RC
The ABO-41RC Remote Control is a very flexible device; it has been
designed for easy operation and to allow users to tailor the operation
for more sophisticated operation. It includes a code library for easy
selection of codes, a dedicated ABUS code bank, all buttons can learn
commands (including bank buttons) all buttons can learn macros (in-
cluding the bank buttons).
Quite often there are products not listed in the library so it is possible
to encode commands into the Remote Control from the ones supplied
with the source components. It is also possible to encode multiple
commands into one key (macros). For example; you could encode into
the SAT bank button commands to turn on your television monitor, the
cable box and select the audio input in the ABUS Multi-Source Multi-
Zone hub. The operator will then only need to press one button to turn
the system on and set it up for normal TV operation. Additional ABO-
41RC can be purchased if required.
Note: Macro strings take time to emit, the operator should take care not to turn the re-
mote control away from the infrared receiver on the Volume Control Module or speaker
before all commands have been generated.
ABUS Compatibility
This product complies with the A-BUS format. The A-BUS format has been adopted by
other manufacturers who make variety of products that can give your system added
flexibility. When looking to expand and/or upgrade your home entertainment system,
be sure to look for products that carry the A-BUS trademark.
