Lowell 100W Mono Volume Control With Standard Wall Plate | Without Bypass | White

Lowell’s 100W mono volume control series is built for installed audio applications where reliable zone-level attenuation is required on 25V or 70V distributed speaker lines. Designed for integrators and audio contractors, these units fit cleanly into standard electrical boxes and ship with a 1-gang wall plate, making them a complete solution for conference rooms, retail spaces, houses of worship, schools, and any facility running a constant-voltage speaker system.

The autoformer attenuator design preserves signal integrity across the attenuation range, stepping down in 3dB increments via a rotary dial with 11 positions. Phoenix-style plug-in screw termination strips simplify field wiring and allow clean, organized connections without soldering. The 14-gauge wire capacity handles the demands of typical commercial installed audio runs, and the unit fits standard electrical outlet boxes with a minimum depth of 2.125 inches, easing retrofit installs.

Available with or without a priority relay bypass, and in multiple wall plate finishes to match existing decor, this family covers the range of zone control requirements found in real-world installed audio projects. The bypass variant integrates a 24VDC relay that enables emergency signal override, a requirement in life-safety and paging applications. Where aesthetics matter, finish options allow the control to blend into any environment.
