• POWERMATCH™ design allows up to 24* VS100pm's connected to one amplifier.
• Wire runs can be looped from room-to-room, saving wire costs and time.
• Eliminates the need for a stereo interface.
• Premium Transformer-Free™ sound quality with ultra high-power handling.
• Detachable wire terminal reduces installation time.
• Slim wall mount design.
• All Knoll Transformer-Free™ products are patent pending.

In use for more than 20 years, Knoll, patent pending, V-Pad Transformer-Free™ volume controls are the safest, most reliable high- power volume controls available anywhere. The POWERMATCH™ design automatically impedance matches, eliminating the need for a load center or stereo interface while allowing up to 24* VS100pm's and speakers to be safely connected to one amplifier. This saves equipment and wire costs while reducing installation time. The relatively small size of the VS100pm with its clearly superior sound quality makes it the ideal choice for all systems.

The VS100pm has a smooth action with a light "feel" when adjusting levels. The VS100pm V-pad design does not generate heat like a transformer or L-pad that can dissipate large amounts of power in low and off positions creating early failures, wall damage or even a fire hazard. Nor is there any sonic degradation at low operating levels. Instead the VS100pm presents the listener with a full frequency response and original dynamic range at all volume positions and power levels. The stereo signal passes to the speakers without the compression effect associated with all autoformer volume controls.

Knoll V-pad Transformer-Free™ technology is the best and most reliable solution for new construction, renovations and upgrades of existing stereo systems.

* The maximum number of VS100pm's per amplifier is dependent on the minimum speaker impedance rating of the amplifier or receiver.

Wire Requirements:

Speaker wire for the VS100pm should be copper, minimum 18 gauge. Runs longer than 33' (10 m) should be minimum 16-14 gauge wire. Two wire pairs (left and right) are run from the stereo amplifier, receiver or nearby VS100pm to the VS100pm volume control, then one wire pair continues to each speaker. When "pre-wiring", leave an extra 3' (1 m) at each end to allow easy component installation.
