Professional four-channel DVB audio satellite receiver
The SAT-4d is the perfect DVB satellite receiver for radio networks. Based on the know-how derived from the FlexDSR series, and customer requirements, the SAT-4d offers uncompromised and reliable reception from 1 up to 4 of your audio programs from satellite.
Flexible in application: The decoder is designed for audio over satellite distribution links. Even synchronization with microsecond accuracy is possible by GPS latency control (useful for simultaneous signal output of all decoders of a network or for audio description).
High compatibility: The SAT-4d supports all known DVB-S/S2 standards and protocols for satellite reception (including 16, 32 & 64 APSK) and offers symbol rates from 0.64 to 45 MSym/s. Furthermore, the SAT-4d supports transport of various private data formats such as ancillary and auxiliary (PID) data as well as contact closures (GPIO).
Redundancy: Even when satellite fails, your radio distribution is safe. Supported by 3 backups the SAT-4d will guarantee that there will always be ‘Music in the air’. A range of backup sources can be selected such as Icecast/Shoutcast, TS over IP and file playback from the internal memory
Pay as you grow: All soft- and hardware components are individually combinable. The scalability from one to four audio channels using software licenses gives you flexibility in planning your network and reducing your costs.
Multi-format audio decoding: Another advantage is the variety of possible algorithms like MPEG1 Layer 2, MPEG2 Layer 3, most AAC profiles including the new xHE-AAC and AAC-ELDv2, OPUS, Ogg Vorbis, PCM, Enhanced aptX, Dolby Digital plus (on request) and more.
Transmission robustness: For the IP backup, Dual Streaming and Pro-MPEG FEC ensure rock-solid backup scenarios. Two hot pluggable power supplies guarantee fail-safe operation.
Smart management: Configuration set-up via an easy-to-use web interface for general settings as well as for backup or fall back. For remote control, the codec offers various possibilities – HTTP, FTP, NMS, REST-API, Ember+ and SNMP. Perfect synchronization can be achieved by latency control and GPS synchronisation.
