Sonifex RB-DSD8

The Sonifex RB-DSD8 is a high-quality 8-channel stereo silence detection unit, designed to safeguard professional audio systems against unexpected dropouts. Built with the reliability and precision that Sonifex is known for, it provides automated backup switching to ensure uninterrupted audio delivery for broadcast, streaming, and playout applications.

Housed in a robust 1U rackmount chassis, the RB-DSD8 constantly monitors up to eight stereo inputs for audio activity. If silence is detected beyond a configurable threshold, the unit automatically switches to an alternative source, such as a standby feed or emergency audio file. This ensures that your station, network, or stream continues to broadcast without interruption — an essential feature for mission-critical environments.

The RB-DSD8 features adjustable silence detection times per channel, giving operators fine control over response behaviour. It also includes front-panel LEDs to provide instant visual status of each channel, along with alarm triggers for integration with existing control systems. With GPIO connectivity, the RB-DSD8 can interface easily with automation systems, routers, and other broadcast hardware.

This device is particularly suited to radio stations, network distribution systems, and content delivery services that require fail-safe operation. Whether protecting against equipment failure, human error, or network dropouts, the RB-DSD8 offers peace of mind and professional-grade resilience.
