Knoll VS100pm Installation Guide

Operation: Knoll volume controls are very easy to use. The VS100pm

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.

Warranty

Knoll Systems warrants the VS100pm sold in the USA and Canada by
authorized Knoll dealers to be free of defects in materials and workmanship.
This warranty extends for three full years from the date of purchase by the
original consumer. Any products returned to Knoll Systems and found to be
defective by Knoll Systems within the warranty period will be repaired or
replaced at Knoll Systems option, at no charge. Knoll Systems will not be
responsible for the actual cost of installation or removal of the product, nor for
any incidental or consequential damages. Some states do not allow the
exclusion or limitation of incidental or consequential damages, so the above
limitation may not apply to you. This warranty gives you specific legal rights.
You may have additional legal rights that vary from state-to-state.

low voltage sections.

Description: The Knoll VS100pm is a twelve-position in-wall
mountable stereo speaker volume control with Powermatch™
(impedance matching) capability. From two to six pairs of speakers
can be safely driven from one stereo amplifier using an equal number
of VS100pm’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.
A rotary switch version is available, model VC100im.

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 6 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 make final trim out quicker, the green detachable connectors with
the VS100pm can be added to the wires now. They are available in
bulk packs without the volume controls from Knoll.
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.

Connection and trim out: Remove the two four position speaker
connectors. Remove about ¼” of insulation from the ends of all wires
connected to the volume control and twist the exposed strands. The
stereo amplifier or receiver outputs (left and right) are connected to
the VS100pm top connector labeled “FROM AMP”. Be very careful to
observe the correct polarity. The VS100pm uses independent floating
grounds so bridged amplifiers can be used safely.

The VS100pm is rated for use with maximum
120 watt per channel amplifiers. DO NOT use
higher-powered amplifiers with this product
for safety reasons.

Wire from the amplifier speaker terminals is always wired in parallel to
all VS100pm volume controls. To make the installation look neat and
tidy, we suggest using one or more WT6 connection strips. When
connecting to the amp make sure its power is switched off. Again
strictly observe wiring polarity.

The maximum number of VS100PM's per amplifer is
dependent on the minimum speaker impedence
rating of the amplifier or receiver.
Suggest minimum 18 g auge sp eaker wire and 12-16
gauge wire for runs longer than 30 feet (10m).

Connect the lower four position connector labeled “TO SPKR” to the
stereo speakers they will control. Again series and parallel speaker
wiring is acceptable so that the impedance the volume control sees is
between 4 and 8 ohms. Be sure to strictly observe polarity, as
incorrect polarity will result in poor bass performance.

When installing the volume control into the wall, we suggest moving
any inside wall fixtures such as vapor barriers away from the volume
control if possible.

To change the color of the plate and knob, start by removing the
plate and knob together. Chose the other color plate and knob. If the
knob is not in the plate insert it by rotating it into the plate. Make sure
the knob is not upside down. Put the black slider on the volume control
in the lowest volume position. Move the knob in the plate to the lowest
volume position. Attach the plate to the volume control with the
bottom alignment tabs inserted first. Snap the rest of the plate on and
test to make sure it works correctly.

Note: This product may contain lead that some states have
determined is harmful. Wash you hands after touching inside portions.
