Lowell 100LVC-SW Single Gang Mono Autoformer Attenuator Volume Control with Rotary Switch, 100W

Put reliable, on-wall volume control where you need it most. The Lowell Manufacturing 100LVC-SW pro audio controller is a single-gang mono autoformer attenuator engineered to give integrators precise, repeatable level control for paging, background audio and surveillance monitoring systems. Rated for 100W and compatible with 25/70/100V speaker lines, it preserves signal integrity while protecting amplifiers and ensuring even coverage across zones. The rotary switch offers 0–10 positions with 3 dB steps for predictable attenuation, making it simple for security and facilities teams to set optimum intelligibility for announcements and monitoring feeds. Phoenix-style plug-in screw terminals reduce wiring time and support 14 AWG conductors for robust installations, and the included one-gang white wall plate provides a clean, professional finish. Ideal for commercial paging, retail, education and security/surveillance deployments, the 100LVC-SW blends durability with installer-friendly features.
