Rami Absence detector digital modulation AES - 1 Alim + SDà

CSS201 is design for continuous monitoring of stereo digital audio signals. Embedded to a broadcast installation, should the main signal disappear. it allows automatic switch to a backup digital signal, and automatic return to the main signal when the problem is cleared.

As well as the audio switch, CSS201 switches a RS232 main/backup to insure continuity of data such as RDS.

Should power supply disappear, the bypass switches the digital input to the digital output, according to the main/backup config in use before the supply loss. This config will be recall on supply return.

The monitor section, allows input/output check using an headphones and bargraph.

A green (normal) /red (backup) indicator on the front panel shows the equipment state, an the user can manually switch the unit to the desired output signal.

• Digital AES/EBU input /output on transformer.
• Digital input sample rate up to 96KHz, no transfer delay.
• Inputs/outputs 48KHz sample rate. An internal sample rate converter (SRC) allows to synchronize all digital inputs at 48KHz.
• No alteration of associated data (index, text...) 
• Digital carrier monitoring for quality and audio, adjustable from -60dBFs to 0 dBFs. On audio loss CSS201 goes on alarm after adjustable delay.
• Full management of the unit uses the embedded web server. It keeps record of the last twenty events, of frames informations in real time, and the state of the switch. A front panel switch recall the factory IP address and a USB port is used for firmware update.
• The remote monitoring of the equipment can be carried through the SNMP agent. Possibility of sending traps in V2c or V2c Inform format.
• Synchronization of the internal clock by SNTP.
• Two relays report supply cuts, a third one for alarm and switch to backup.
• CSS201 is 19-inch, 1 U.
• Option SD: The Additional input audio backup via SD card. This allows a second possible continuity program if the emergency chain is also in default
