System ON
- Single Source Hub and active audio source to activate the
VCM’s then if any function button is pressed the system will become active.
Multi Source Hubs become active as soon as a source is selected.
Input Selection [1]
- The system will restart on the last source selected. One
of the four input LEDs [5] will indicate which input has been selected. The
input can be changed by pressing left or right buttons [1].
Volume Level [2]
- Initial start-up: A volume Up command will start the
VCM at a low listening level. Single Source Hubs: When the VCM is in
standby mode, tap the AB-44’s “UP” button or the AB-46’s “Power Button”
[3] or “Volume” buttons on a remote control [12] the VCM will restart at the
last level selected. Multi Source Hubs: When Global off is selected [13]
on remote controls or a long push on AB-46 Off button (3)] the VCM’s will
reset to the start-up level. The AB-46 includes a jumper switch on the rear
to enable restart at the last level selected before Global Off command or
system restart. While the level is being adjusted, the input
LEDs [5] will ripple left or right.
Remote Control [4]
- The VCM may be operated by
remote control. The IR remote must have clear line-of-site
to the IR Receiver. The VCM can also relay IR remote
control commands to the hub and connected source
components. It will repeat standard 38 kHz commands
and 56 kHz commands which are often used in satellite
receivers. You may experience diffi culty with some remote
control commands on some components. The operating
range can be aff ected by sunlight and some lighting
systems.
Mute and Global Mute [3]
- A VCM can be muted indi-
vidually by pressing the mute button, this will turn off the
backlighting to the volume control [2] and input selection
buttons [1]. The backlighting of the mute [3] and input indicator will [5] remain
on. If there are other VCM’s connected to the same zone their status will not
be aff ected. If the mute button [3] is pressed for more than three seconds
the whole Forté A-BUS system will turn mute. When the system is muted the
infrared relay will remain active.
Backlight Adjustment [6 & 16]
- The backlighting level of the function
buttons [1] [2] [3] and the source LED’s [5] can be adjusted to individual
requirements.

The AB-44 & AB-46 include Dynamic Effi cency
(DE) amplifi cation delivering higher power
output, improved sound quality and lower energy
consumption. Also included is an optional
socket for High Dynamic Effi cency (HDE). When
a second CAT5 cable is connected from the
power [15] socket to any A-BUS hub output, the
VCM will provide twice the output power.

This Keypad Volume Control Module (VCM) has been
designed to work with Forté A-BUS Multi-Source Hubs using
standard A-BUS commands. It will operate with other single-
source and multi-source hubs; however, some functionality
such as source selection will not be required.
These functions can be accessed with an A-BUS remote control handset
containing the correct codes.
Note:
For comprehensive instructions please also refer to the instructions
supplied with your Forté A-BUS multi-source hub.
