Application Examples

Satellite Radio Reception: Receive and decode high-quality audio broadcast programs directly from satellites via DVB-S/S2/S2X.

Terrestrial FM Broadcasting The IRA-3000 is an ideal solution for remote transmitter sites. It receives national or syndicated radio programs via DVB-S/S2/S2X satellite links and outputs professional-grade analog or AES/EBU digital audio (via XLR interfaces) directly to local FM exciters.

DAB/DAB+ Digital Radio Networks Operating as a high-fidelity satellite-to-baseband receiver, the unit decodes satellite audio feeds into pristine AES/EBU digital audio or IP streams. This provides the high-quality source audio required to feed central DAB Multiplexers for subsequent ETI or EDI ensemble generation.

Cable TV & Radio Headends: The IRA-3000 supplies decoded analog or AES/EBU audio, or SPTS IP streams, to downstream headend equipment. FM or DVB-C RF modulation requires a separate external modulator.

IP Audio Distribution & STL (Studio-to-Transmitter Link) Acting as a highly efficient gateway, the IRA-3000 converts RF signals or ASI feeds into Single Program Transport Streams (SPTS) over UDP/RTP (multicast or unicast). This enables reliable, IP-based audio distribution to remote broadcast sites or enterprise IPTV networks.

IPTV Headends: Feed the decoded high-quality radio broadcasts and seamlessly inject them into IPTV networks.

FAQ (Frequently Asked Questions)

What is the primary function of the BLANKOM Professional Audio IRD?

The BLANKOM Professional Audio IRD (Integrated Receiver Decoder) is an operator-class hardware solution engineered to receive professional audio payloads from various input interfaces—such as satellite (DVB-S/S2/S2X), IP, or ASI networks—and decode them into high-fidelity analog and digital audio outputs for radio broadcasting, studio monitoring, and commercial audio distribution networks.

Which RF input and tuner options are available on this Audio IRD?

The IRA-3000 provides one DVB-S/S2/S2X satellite tuner input. The IRA-3000T variant provides one switchable DVB-C/T/T2/ISDB-T tuner input instead. These are alternative hardware configurations selected when ordering; satellite and cable/terrestrial reception are not combined in the same tuner.

What physical audio output interfaces are provided for studio integration?

Designed to meet strict broadcast studio standards, the unit is equipped with a comprehensive set of output interfaces. It provides professional balanced digital audio via AES/EBU (XLR) interfaces, as well as high-fidelity balanced analog stereo audio (XLR) outputs. This dual-architecture ensures noise-free, studio-grade signal distribution to broadcast mixers, transmitters, or local amplification systems.

Does the device support IP-based audio streaming inputs?

Yes. The IRA-3000 provides two UDP/RTP IP inputs via 100/1000 Mbps RJ45 data ports, supporting unicast and multicast reception. It also provides two SPTS outputs over UDP/RTP for IP distribution.

Which professional audio compression layers and codecs can the IRD decode?

The IRA-3000 supports MPEG-1 Layer II, MPEG-2 AAC, AC-3, E-AC-3 and DRA audio decoding, with sampling rates of 44.1 kHz and 48 kHz. HE-AAC is not supported.

How does the device handle conditional access and encrypted audio feeds?

The IRA-3000 does not support BISS descrambling. Encrypted feeds must be decrypted by suitable external equipment before being supplied to the device.

Does the Audio IRD support multi-channel decoding or multi-program selection?

Yes, the device integrates an advanced internal demultiplexer. When receiving a Multi-Program Transport Stream (MPTS) via satellite, IP, or ASI, operators can use the management interface to explicitly select the specific audio PID or radio service channel that needs to be decoded and routed to the physical XLR outputs.

How are Data PIDs handled on the IP output?

Data PIDs listed in the programme’s PMT are automatically carried with the transport stream on the Ethernet UDP/RTP output, without additional PID-specific configuration. The output consists of MPEG-TS packets, rather than the raw data payload.

Handling unknown PID types requires evaluation of a sample transport stream and custom firmware development, including an additional Web GUI configuration option. This functionality is subject to project-specific validation and is not included as standard.

What monitoring and remote configuration capabilities are integrated into the system?

The IRA-3000 can be configured via its built-in Web GUI or the front-panel LCD and control buttons. Firmware updates are available via Web management. SNMP is not supported.

Which power supply configuration is standard?

Both IRA-3000 and IRA-3000T include dual hot-swappable redundant power supplies as standard. A single power supply is optionally available instead of the standard dual power supply configuration.

Are technical data sheets and purchasing ordering guides available for this model?

Yes. The datasheet is available in the Downloads section of this page. It covers the input and output interfaces, supported audio formats, power supply configuration, mechanical and environmental specifications, and ordering options for IRA-3000 and IRA-3000T.
