2wcom’s FlexDSR02+ and FlexDSR04+ Digital Audio Satellite Receivers


2wcom’s new FlexDSR02+ and FlexDSR04+ digital satellite receivers set a new benchmark in audio contribution via satellite and IP, offering far more versatility, power and integration than the previous generation of satellite receivers.

With an exceptionally comprehensive feature set, the FlexDSR02+ and FlexDSR04+ support all major audio formats, provide fail-safe dedicated hardware, automatic program switching, full regionalization capabilities, SIRC remote control through satellite, and many more functions that allow broadcasters greater operational flexibility and cost savings.

The FlexDSR02+/04+ accepts input from satellite (DVB-S/S2), internet (IP), and synchronous transmission lines (STL with ASI). With its SD card-based internal memory capacity, FlexDSR02+/04+ facilitates a wide variety of additional back up solutions and transmission scenarios.


2wcom’s SIRC (Satellite Inband Remote Control) provides remote control and management of the entire network of IRDs via satellite, without requiring an additional backline. These advanced control facilities make it possible for radio stations to streamline the integration of profitable regionalized commercials and other content. Full standard control via SNMP and web interface is also provided.

FlexDSR02+/04+ deliver a more secure and high-quality experience for both operator and listener. Automatic weightbalancing of quality parameters and failover switching to alternative program input sources (satellite, IP-line, ASI, SD card) is complemented by seamless audio fading between different sources (backup lines or SD card).


“It is the comprehensive range of features and operations supported by FlexDSR02+/04+ that makes it a substantial advance on the previous generation of IRDs,” said Werner Drews, managing director of 2wcom. “With its diverse and flexible options for audio back up, support for local commercials, automated fading between sources, professional audio decoding, RF and MPEG parameter monitoring, SIRC control and more, it’s almost impossible to think of something the FlexDSR02+/04+ won’t do.”

Supporting up to four audio inputs, the FlexDSR02+ and FlexDSR04+ are 19” 1U units prepared for a rack installation with display and jogwheel, diverse tuner models, remote control, SNMP v2c, a wide range of professional audio analog and digital outputs, Gigabit IP, ASI, relays and inputs, and internal memory. With its fanless, hard disk free hardware design, the FlexDSR02+/04 is inherently more reliable than PC-based systems, and has a remarkably short boot-up time of 5 seconds.


The outstanding versatility of the FlexDSR02+/FlexDSR04+ means that users can chose between MPEG 1/2 Layer 1,2,3, MPEG 2/4 AAC LC, HEv1&v2 and AC3, to achieve the optimum operational efficiency. In addition, the unit provides built-in monitoring of important operational RF signal and MPEG parameters, with monitoring of audio via an internet backline also possible.

With support for the latest codecs, inbuilt monitoring of operational parameters, and superfast reliable hardware easily upgradeable with software options, the FlexDSR02+ and FlexDSR04+ is the most innovative IRD available.
