5. Remove the knob
6. Tighten the nut without moving the tab
7. Replace the knob. The tab position will prevent the
knob from turning to the point where the impedance to-
ward the amplifier becomes too low.
Note that there are two more settings available: position
11, which is for two 8-Ohm speakers per channel, and
position 12 which is fully ON and should be used only for
one 8-Ohm speaker per channel. The following chart
will help you properly position the impedance matching
metal tab. Double check the setting on the volume con-
trols by counting the “clicks” from left to right.

9.6.4 Installing the Decora Digital
Volume Controls
The connection from the Wall Mount Decora Volume
Control to the Volume Control Hub is made with a single
Category 5 or 5e wire using all 8 conductors, usually run
inside a wall. Only digital control signals, and not stereo
signals are routed to the Volume Control Unit.
✍
Take Note: If more than one Volume Control Unit is to be
connected to a Hub (where multiple units will be controlling
the same speakers) the 8-wire connections to the Volume
Control Units must be parallel.
To install the Volume
Control Unit:
• The unit may be
mounted in any sin-
gle-gang, low-voltage
mounting ring, or an
electrical box that is
deep enough to ac-
comodate the device
and associated
wiring.
