Knoll VC100SS 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.
The Knöll VC100ss silent start transformer free room
volume control 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 VC100ss
has 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 distortions are barely measurable.
For best results when connecting 2 or more 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 VC100ss can be installed in an electrical junction
box but it is not required. Make sure the VC100ss 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
VC100ss in an electrical box, remove the bottom and
top knockouts or drill holes to let heat dissipate.
3. Never install the VC100ss 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 VC100ss 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,
VC100ss volume control and speakers together. Never
connect left and right channel wires of the positive OR COPYRIGHT 1996-2002

C
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 VC100ss "SPEAKER" outputs to the
corresponding speaker terminals as indicated on the
VC100ss connector.
8. Connect the two 12VDC power supply wires to
the VC100ss as shown taking careful note of the
polarity. These power supply wires can be daisy
chained from room to room.
9. Plug the 12VDC power supply into the switched
outlet socket on the stereo amplifier or receiver. The
VC100ss will always default to the red standby
mode when the stereo is switched off. To hear sound
in a room after the stereo has been switched on,
press the small button. The led glows green and the
sound level can be adjusted by rotating the volume
control knob.
