SD1+ is a silence detector for broadcast paths, switching from a primary programme feed to a backup input when the level remains below a configured threshold for the defined time.

• Stereo or dual-mono operation, with independent parameters per channel.
• Silent switching to the backup input, manual or automatic return, and smart fail and recovery modes.
• GPIO for alarms, remote starts and external control, with bypass relays on power failure.
