Knoll VC100IM - Manual

Operation:

Knoll volume controls are very easy to use. The VC100im

has a total of 12 different volume settings including fully off.

To increase the volume (in this room only), turn the volume control
knob clockwise. To lower the volume, turn the volume control knob
counterclockwise.

To set the correct amplifier or receiver volume setting we suggest that
you turn the Knoll room volume control in one room to maximum.
Adjust the amplifier or receiver volume to the loudest comfortable
setting you will use and no further or louder. In this way the Knoll

volume control has the most usable settings. If the amp volume
control was set louder, the Knoll volume control would have to be
turned down to be back at a comfortable level with less overall volume
positions available

electrical codes and regulations.

Caution

: Do not install these keypads in an electrical junction box

with 110V or higher unless an approved barrier separates the high and

low voltage sections.

Description:

The Knoll VC100im is a twelve-position in-wall

mountable stereo speaker volume control with impedance matching
capability. From one to eight pairs of speakers can be safely driven
from one stereo amplifier using an equal number of VC100im’s.

Separate impedance matching components are not required. The Knoll
WT6 one stereo input to six stereo output connection strip is available
to neaten the wiring of larger systems.

Basic System Layout and Pre-Wiring

: A stereo amplifier controls

multiple pairs of speakers. Decide where the speakers and volume
controls will be placed in the various rooms. When wiring always leave

an extra couple of feet of wire at both ends so installation of the
speakers and volume controls is quick and easy. Up to eight pairs of 8-
ohm speakers can be safely connected to one amplifier.

Run a

fire-rated

two-conductor speaker wire (14-18 gauge wire) from

each speaker to the volume control location in each room. Next, run a

four-conductor speaker wire from the volume control to the amplifier
location. Ideally each run back to the amplifier is a home run, but
wires can be daisy chained from room to room. If you plan to daisy
chain the wiring we suggest using larger 14-gauge wire. If 2 pairs of

speakers are being controlled by 1 volume control, wire the 2 pairs in
series if they are 4 or 6-ohms and parallel if they are 8 or 16-ohms.
Our web site has information on how to wire in series and parallel.

Warning: Never attempt to make the final combined speaker
impedance less than 4-ohms as this may cause safety issues.

To tidy up the installation, use Knoll’s WT6 seven position wire

connection strip at the amplifier. Two or more may be required for
some installations.
