ITEL STL-SAT CHANGEOVER

STL-SAT Changeover with RDS recoding

The ITEL STL-SAT Changeover is an automatic audio change-over system with RDS recoding. This unit realizes an automatic audio changeover between a stereo signal coming from a satellite receiver or other source and a MPX composite signal coming from a STL receiver.

Any of the two audio sources can be selected as the main source and the unit will continuously monitor its parameters, including audio level, pilot level, PI code and RDS quality (only audio level monitoring applies to the stereo audio source).

When any of the user-defined alarm thresholds are exceeded on the main source, the unit will switch to the backup source, getting back to the main, once it recovers.

A GSM modem can be fitted internally for remote control and alarms signalling through SMS.

A unique feature of this unit is the capability of suppressing the incoming RDS signal and superimposing a new, internally generated one or replacing its AF tables only.

In this latter case, all other pre-existent dynamic services will pass through the unit unmodified.
