The Lowell 100LVC-DW is a 100-watt rotary volume attenuator designed for 25V and 70V distributed speaker systems. Its autoformer design provides convenient local volume control for commercial audio installations while maintaining compatibility with constant-voltage speaker lines.
The 100LVC-DW provides 11 volume positions from 0–10 with 3 dB attenuation per step, delivering up to 33 dB of total attenuation. The rotary dial makes it easy to adjust speaker volume directly from the wall.
Designed for professional distributed audio systems, the 100LVC-DW uses Phoenix-style plug-in screw terminals and accommodates speaker wire up to 14 gauge. The control includes a white decorator-style 1-gang wall plate, providing a clean appearance for offices, classrooms, retail spaces, restaurants, and other commercial environments.
The unit fits a standard electrical box with a minimum depth of 2.125 inches, making it straightforward to incorporate into new or existing installations.
