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 auto former 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.
