AUDIO:
Audio input from the main amplifier’s tape output or second zone
output.
STATUS:
There are several ways to activate an A-BUS system. When not in
operation the A-BUS system is in mute mode. It is activated by;
• Automatic Signal Sensing (Default): The Hub automatically detects when audio
signal is present and activates the A-BUS system. 30-seconds after
the audio signal ends the system returns to mute. Note: AB-61 does
not have auto sensing.
• Main System Sensing (Preferred): A-BUS also activates automatically when the
main sound system is switched on (including source components). A
12-volt 100-300 mAmp power pack should be plugged between the
main amplifier’s switched power outlet and the hub’s Status input.
POWER:
Power supply for system power. Should not to be connected to the
main amplifier’s switched output.
Note:
A second power supply is
required for the AB-663 bank B (expansion for extra 4 rooms)
IR EMITTERS: To relay infrared control signals to source components. IRR-110
single or IRR-120 dual emitters may be used. The emitter head
should be placed directly over the components infrared receiver.
A-BUS OUTPUTS: Cat5 patch leads are used to connect the Forté A-BUS room
units.
SENSED INPUT ADJUSTMENT: Line level input adjustment of +2, -10db on the
sensed input. (AB-663 hub only).
EXPANSION: Ports to add additional zones
• OUT:
Connects to additional hubs to add more zones or rooms.
• IN:
Connects to the direct input of an A-BUS/
ready
amplifier, an A-BUS
input selector (ABS-40), and input expansion
LOCAL IR: A Forté IR receiver may be connected to this socket for control of the
source components from a room that does not have a Forté A-BUS
IR module.

Note:
The hub can be directly connected to an A-BUS/
ready
amplifier via the Expansion
Input port. The A-BUS system automatically powers up when an A-BUS/
ready
amplifier is
switched on. This may be done via remote control from any room. The hub power supply
is still required.
Thank you for your Forté A-BUS purchase. To complete your Forté A-BUS installation
also refer to the manual of the volume control module and/or the A-BUS/
direct
speaker.
