RC1 Red Alert

Product Overview

The RC1 Red Alert is a compact audio level monitoring and protection device designed for use in venues and live sound systems. It continuously monitors audio levels and provides a clear visual warning when signal levels become excessive.

If preset limits are exceeded, the RC1 can automatically mute or reduce audio output to protect sound systems and help maintain compliance with noise regulations. A key-operated override allows authorised control, while a relay output can trigger external warning or control systems.

The RC1 Red Alert is commonly used as a safeguard against system overload, unauthorised level changes and excessive sound levels in professional audio environments.
