DVB Audio Satellite Receiver

Professional four-channel DVB-S/S2 audio receiver with full analog stereo support

The SAT-4da is the perfect DVB satellite receiver and decoder for radio networks. Based on the know-how derived from the FlexDSR series, and customer requirements, the SAT-4da offers uncompromised and reliable reception of up to 4 audio programs from satellite.

Flexible in application: The SAT-4da is perfect for high-density analog installations, coming with 8 XLR outputs to support up to 4 analog stereo channels. The decoder is designed for audio over satellite distribution links. The combined XLR connectors can be used for digital or analog output (up to 4 stereo pairs on 8 XLR outputs).

High compatibility: The SAT-4da supports all known DVB-S/S2 standards and protocols for satellite reception (including 16, 32 APSK) and offers symbol rates from 1 up to 45 Msym/s. Furthermore, the SAT-8d supports transport of various private data formats such as ancillary and auxiliary (PID) data as well as contact closures (GPIO).

Redundancy: Even when the satellite fails, your radio distribution is safe. Supported by 3 backups, the SAT-4da 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.

Multi-format audio decoding: Another advantage is the variety of possible algorithms like MPEG-1 Layer 2, MPEG-2 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 synchronization.
