Beale Street VCSI Impedance Matching Volume Control, Slider Knob

Optimize multi-zone audio and monitoring with the Beale Street Audio VCSI impedance matching slider volume control. As a dedicated audio controller, the VCSI removes the guesswork of speaker impedance: installers can connect multiple volume controls and speaker pairs to a single properly powered amplifier without jumpers, impedance tables, or switch settings. Built for commercial AV and security environments, it delivers dependable power handling—105W continuous RMS per channel with 350W peak capacity—so paging, background music, and surveillance audio remain clean and consistent under real-world loads. The VCSI’s DC to 500 kHz frequency response preserves voice and wideband signals used in modern monitoring systems, while removable screw terminals and single-gang electrical box mounting speed installation and service. Ideal for integrators working on retail stores, conference rooms, control rooms, and surveillance monitoring stations, this compact slider knob control combines precise level adjustment with rack-and-field-friendly wiring. Upgrade your distributed audio or security audio chain with the Beale Street VCSI — contact us to specify it for your next AV, security, or monitoring project.
