12. The Functional Volume
Control
Introduction
The Functional Volume Control (FVC) is a simple yet effective hardwired
remote control that is designed to be used with the SUB 8 as part of a
ProDesk™ 2.1 System (future subwoofer models may also take advantage of
this feature). For 5.1 channel systems the FVC should not be used and
instead the Blue Sky BMC should be used. (For more information on the
Blue Sky BMC, please visit www.abluesky.com)
Connection and Operation
The FVC is designed to connect to the SUB 8 via standard 6 conductor modem
cable and RJ11 jack (included with the remote). The maximum length for this
wire should not exceed 100 feet.
Once connected, the Functional Volume Control (FVC) controls the gain of the
Left and Right input channels of the Sub 8. The FVC does not control the gain
of the external / direct SUB IN channel. However, the FVC will control the level
of the Left & Right summed and derived subwoofer signal that is sent to the
SUB OUT jack and the internal subwoofer amplifi er. Calibration levels between
the SUB 8 and SAT 5 are not affected by the FVC and calibration should be
done as stated in the ProDesk™ manual.
Below is an outline that shows how the SUB 8 and FVC interact, either when the
remote is connected or not.
1. Power Up
A. Volume Control Not Connected
1. L/R gain defaults to 0dB (unity gain)
B. Volume Control is connected
1. L/R channels are muted
2. LED on Remote Flashes
3. User must turn Gain control fully counterclockwise
until the LED stops fl ashing and is on continuously
4. The FVC is now operating normally
2. FVC cable is disconnected during normal operation
A. When disconnected, gain stays at current level until
power is recycled or the FVC is reconnected
3. Volume control is attached after power up
A. Volume control will not operate and LED will fl ash
B. User must turn Gain control fully counterclockwise until
the LED stops fl ashing and is on continuously
C. The FVC is now operating normally
