The Sonifex RB-DSD1 digital silence detection unit works in a similar way to the Sonifex RB-SD1 analogue silence detection unit, but has AES/EBU, S/PDIF and TOSlink inputs and outputs instead of analogue inputs and output respectively. Designed to switch from one input to another in the event of loss of audio, the unit is ideal at transmitter sites, or after the master output of a studio, to switch in another audio source, or simultaneous broadcast, should a master source fail.

Sonifex RB-DSD1 Features:

  • Master Mode: In this mode the digital output sample rate is simply set by, and locked to, the internal on-board clock generator. No sync signal is used or required.
  • Auto Sync Mode: In this mode the digital output sample rate follows the selected sync input. When the sync signal is not present the output sample rate will be set by, and locked to, the internal on-board clock generator at the selected output frequency.
  • Auto Lock Mode: In this mode no output will be generated until lock is achieved with a sync signal. The digital output sample rate now follows the sync input. If the sync signal is removed then the output sample rate will be set by, and locked to, the internal on-board clock generator at the closest frequency available to the previous sync input.
  • Slave Mode: In this mode the digital output sample rate follows the syncinput. When the sync signal is not present the digital output is turnedoff.
