Archives - 5 Digital audio modulation monitoring

CSS510 is designed to permanently monitor five digital stereo audio signals. Connected as an insert in the digital path, should a problem occur, it allows switching to a spare digital signal, according to a decreasing priority scale, and to come back to the priority source as soon as the problem is cured.

CSS510 is able to handle several error types, classified in two groups. The first one analyses the AES /EBU signal : CSS510 can detect blanks or saturation (user defined threshold). The second group regards the digital quality: CSS510 monitors the digital carrier, the sampling frequency, the path quality. The user defines the necessary checks. Each group controls a dry loop on channel 1. The loop closes on alarm, to start an external equipment.

The monitoring section allows to continuous check of CSS510 inputs/outputs. An embedded 96kHz D/A converter delivers an analog signal to the Sub D9 on the rear panel, one headphone output and and bargraph. Thus, monitoring is very efficient.

  • Digital AES/EBU inputs /outputs use transformer.
  • Management of signals up to 96KHz.
  • Digital audio parallel monitoring, no transfer delay.
  • No alteration of associated data (index, text...).
  • Output is synchronous with enable input, and synchronous switching from main signal to spare signal.
  • Able to check audio level and digital path.
  • Parameters editing and display using embedded web server.
  • Audio level threshold, ranging from 0 to -60 dBFs.
  • Audio overload threshold ranging from 0 to -12 dBFs.
  • 4 audio monitoring modes : Left, Right, Left+Right, Left*Right.
  • Manual mode, output channel is selected from the front panel or remote control.
  • Automatic bypass input/output in case of power fail.
