Rami Détecteur d'absence de modulation numérique - 5 entrées

Rami Digital modulation absence detector - 5 inputs

CSS510-2 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.

CSS510-2 is able to handle several error types, classified in two groups. The first one analyses the AES /EBU signal : CSS510-2 can detect blanks or saturation (user defined threshold). The second group regards the digital quality: CSS510-2 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 CSS510-2 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.
• Analog input assignable on one of the 5 inputs.
• A digital sync input on the rear panel.
• Management of signals up to 96KHz.
• Digital audio parallel monitoring, no transfer delay.
• No alteration of associated data (index, text...).
• Output synchronized internally or via external sync input.
• Able to monitor both audio level and digital link.
• 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 and Right, Left or Right.
• Manual mode, output channel is selected from the front panel or remote control.
• Automatic bypass input/output in case of power fail. In By-Pass, the continuity of the program is ensured on both outputs by a double transformer
• "ALARM" delay programmable from 1 to 99s.
• "RETURN" Delay programmable from 1 to 99s.
• Outputs "ALARM" on optos-mos (dry loops).
• 2 independent digital outputs.
• Monitoring: bargraph, headphone output (24 bit/96KHz D/A converter).
• Balanced analog stereo monitoring output on Sub-D9.
• System Log of 200 lines of events.
• Supervision by SNMP (V2c and V2c Inform).
