Radio Design Labs ST-VP1 Voice Over Page Module

Product Description

The RADIO DESIGN LABS ST-VP1 is a voice over and paging module designed for audio signal processing applications. It allows an audio system to interrupt or duck background music or ambient audio when a live voice or page signal is present, restoring the original audio feed once the page ends. This type of module is commonly installed in commercial and institutional audio distribution systems where paging and background audio run on shared zones. Installation is typically handled by low-voltage audio technicians or systems integrators working with distributed audio infrastructure.

The ST-VP1 is suited for commercial environments including retail spaces, offices, schools, and facilities that require coordinated paging over background audio. It functions as part of a larger audio signal chain and is typically rack-mounted or integrated into an equipment bay alongside amplifiers, mixers, and audio distribution components. Its design targets professional audio system builds where reliable voice-over triggering is a core operational requirement.

Key Features

• Voice over and paging function automatically ducks or interrupts background audio during page events
• Designed for integration into commercial distributed audio systems
• Audio signal processor category suitable for multi-zone installations
• Sold as a single unit for individual zone or channel builds

Compatibility

Designed as an OEM-style module for use in professional distributed audio and paging systems requiring voice over or page-interrupt signal processing.

Installation Notes

Installation should be performed by a qualified low-voltage technician or licensed audio systems integrator. Power down the audio system and disconnect signal sources before connecting or disconnecting the module. Follow applicable low-voltage wiring codes and the facility audio system schematic during integration. Verify signal levels and gain staging at the system level after installation to confirm proper voice over triggering behavior.
