Lowell 200LVC 200W Mono Autoformer Attenuator Volume Control with Rotary Switch, Stainless Steel

Manage background music, paging and surveillance audio with confidence using the Lowell Manufacturing 200LVC 200W Mono Autoformer Attenuator Volume Control. Designed for 70V/100V single- or multi-speaker lines, this rotary volume control delivers dependable, repeatable attenuation so installers can balance zones and optimize speech intelligibility in retail, education, corporate and security environments.
