ST-VP2
Overview
Ensure every emergency page and routine announcement is heard with confidence — the Radio Design Labs ST-VP2 Automatic Ducking Module provides seamless, hands-free voice-over control for paging and mass notification systems. Designed for integrators and AV/security professionals, this ducking module automatically senses a line-level voice page, attenuates background music via an adjustable fade depth, and smoothly restores music after the page completes. The ST-VP2 includes a built-in AGC/compressor on the music input to maintain consistent audio levels and protect voice clarity in noisy environments.
Compact (3" x 0.9" x 1.6") and powered by 24V DC, the ST-VP2 easily mounts into line-level inputs on paging amplifiers and works with telephone paging systems or preamplified microphones. Front-panel LED indicators simplify setup and confirm proper input levels, speeding installation in security, surveillance, monitoring and public-address applications. Ideal for schools, shopping centers, hospitals and any facility requiring reliable mass notification and unobtrusive audio mixing. Contact your systems integrator or our sales team to specify the ST-VP2 for your next security or paging deployment.
