The Lowell 100LVC is a 100-watt rotary volume attenuator designed for 25V and 70V distributed speaker systems. Its autoformer design provides reliable level control for commercial audio installations while maintaining compatibility with constant-voltage speaker lines.
The 100LVC features 11 volume positions from 0–10 with standard 3 dB attenuation steps, providing up to 33 dB of total attenuation. A rotary dial makes it easy to adjust speaker volume directly from the wall.
Designed for professional installations, the 100LVC uses Phoenix-style plug-in screw terminals that accept wiring up to 14 gauge. The control is supplied with a standard 1-gang stainless steel wall plate and fits a standard electrical box with a minimum depth of 2.125 inches.
