Lowell 25LVC 25W Mono Autoformer Attenuator Volume Control with Rotary Dial, 1-Gang, Stainless Steel

Deliver reliable, controllable audio for paging, background music and security applications with the Lowell Manufacturing 25LVC. This 25W mono autoformer volume control is designed for commercial audio controllers and security/surveillance systems, giving installers precise level adjustment on 25V/70V/100V speaker lines. The unit’s stepped attenuation (3 dB increments with two 6 dB steps before off) provides predictable volume changes—ideal for monitoring rooms, lobby paging and distributed PA zones. Built into a standard 1-gang stainless steel wall plate with a durable black rotary knob, the 25LVC presents a professional finish and vandal-resistant profile suited to high-traffic environments. Phoenix-style plug-in screw termination strips make pre-wiring and service fast, while support for up to 14-gauge wiring accommodates long runs and commercial deployments. Whether you’re specifying audio for a retail store, school, hospital or security control room, the Lowell 25LVC streamlines installation and delivers consistent, high-quality level control. Add the 25LVC to your next security, surveillance or AV monitoring project for dependable, easy-to-service volume management.
