RDL ST-VP2 — Automatic Audio Ducking Module

The ST-VP2 Automatic Ducking Module provides automatic attenuation of background audio whenever a priority or live-microphone signal is detected, improving speech clarity for paging and live announcements. It eliminates the need for manual level adjustments and simplifies operation in commercial audio systems. The module integrates with existing program audio feeds and priority inputs to ensure voice sources are heard clearly over music or other program material. By automatically lowering program levels during announcements, the ST-VP2 maintains consistent intelligibility without operator intervention. This reduces errors during operation and helps deliver a professional audio experience in facilities with frequent paging or intercom use.
