Knoll VC100 User manual

Congratulations for choosing the finest stereo
volume control available. To assure correct
installation and to realize the full potential of this
new volume control, please read and follow
these instructions carefully. If you have questions
or comments, please don't hesitate to call or
write your Knöll dealer.
Knöll transformer free high power room volume
controls are designed to fit standard electrical
junction boxes (J-boxes). Standard plate colors
are white, bone, black and brass. Plates can be
decora or standard style. The VC100 has a
power capacity of 100 watts RMS per channel
with 350 watt peaks for 5 seconds permissible.
Speakers can be 4-16 ohms. The VC100
features floating independent grounds so bridged
amplifiers can be safely used. Frequency
response is DC to 500,000 Hz +/- 0.1 dB at all
power levels up to 350 watts. THD and IM
distortion is barely measurable. For best results
when connecting 2 or more VC100 volume
controls to one amplifier or receiver, use a Knöll
transformer free stereo interface.
INSTALLATION TIPS:
1. Follow all electrical and building code requirements
in your area.
2. The VC100 can be installed in an electrical junction
box but it is not required. Make sure the VC100 white
elements do not touching anything, especially plastic
vapor barriers. To obtain the full power rating, volume
control heat needs to be ventilated. When installing the
VC100 in an electrical box, remove the bottom and top
knockouts or drill holes to let heat dissipate.
3. Never install the VC100 in the same electrical junction
box as high voltage equipment (75+ volt) unless an
approved barrier separates high from low voltage
equipment.
4. Speaker wire can be solid or stranded. Suggested
minimum wire size is 16 gauge and 12-14 gauge for
runs longer than 30' (10m).
5. Wire both left and right speaker outputs from the
amplifier, receiver or interface to the VC100 inputs.
6. Proper polarity is essential to achieve best speaker
sound quality with maximum output. Be careful to wire
the + or positive terminals of the amplifier, interface,
VC100 volume control and speakers together. Never
connect left and right channel wires of the positive OR

ground (-) together as amplifier damage may
result. The - or negative terminals of the
amplifier, volume control and speakers must be
wired as shown in the diagram.
7. Wire the VC100 outputs to the corresponding
speaker terminals as indicated on the VC100
connector.
