IRA-3000 / IRA-3000T

The BLANKOM IRA-3000 receives two audio programmes from RF, ASI or IP transport streams and decodes them to professional balanced analogue XLR and AES/EBU digital audio outputs. IRA-3000 uses a satellite tuner; IRA-3000T uses a switchable cable/terrestrial tuner. Dual hot-swappable redundant power supplies are standard.

Key Features

  • Dual-programme audio decoding
  • MPEG-1 Layer II, MPEG-2 AAC, AC-3, E-AC-3 and DRA
  • 44.1 / 48 kHz sampling; adjustable gain −24…+12 dB
  • Dual hot-swappable redundant PSU as standard; single PSU optional
  • Front-panel LCD/keypad and Web GUI management; Web firmware updates
  • No HE-AAC, BISS descrambling or SNMP support

  • 2 SPTS outputs over UDP/RTP for IP audio distribution

Technical Overview

BLANKOM IRA-3000 receives professional radio services from an RF tuner, ASI or UDP/RTP IP and decodes two audio programmes for analogue balanced XLR and digital AES/EBU outputs. It also provides two SPTS IP outputs for further distribution. Reception, audio decoding and IP forwarding are separate steps in the signal chain.

The IRA-3000 satellite version uses a DVB-S/S2/S2X tuner. IRA-3000T replaces it with a switchable DVB-C/T/T2/ISDB-T tuner; the two reception systems are alternative hardware configurations. Both versions retain two ASI inputs and two UDP/RTP IP inputs over 100/1000 Mbps RJ45 interfaces.

The technical table lists MPEG-1 Layer II, MPEG-2 AAC, AC-3, E-AC-3 and DRA, with 44.1/48 kHz sampling and adjustable gain from −24 to +12 dB. The Web GUI or front-panel LCD/buttons provide configuration. Hot-swappable redundant dual power supplies are standard; a single PSU is an option.

Typical Applications

Remote FM transmitter reception

Receive a satellite or IP radio feed, select the required programme and supply analogue XLR or AES/EBU audio to a compatible FM exciter. RF modulation is performed by the external transmitter equipment.

Radio headend and IPTV distribution

Receive radio services through the selected tuner, ASI or IP input and distribute the selected programmes as two SPTS over UDP/RTP. Plan codec compatibility, destination addresses and network capacity for the receiving system.

Studio monitoring and digital radio preparation

Decode incoming services to professional analogue or AES/EBU audio for monitoring or downstream radio equipment. Generation of DAB ensembles, ETI/EDI or other transmission formats requires the appropriate external system.

Engineering FAQ

What distinguishes IRA-3000 from IRA-3000T?

IRA-3000 has a satellite tuner; IRA-3000T uses a switchable cable/terrestrial/ISDB-T tuner. Select the required RF hardware when ordering.

Which non-RF inputs are available?

Two BNC ASI inputs and two UDP/RTP IP inputs are specified. The Ethernet data interfaces adapt to 100/1000 Mbps.

How many audio programmes can be decoded?

The unit is a dual-programme audio receiver/decoder. Select the required radio services and route their audio to the professional outputs.

Which physical audio outputs are provided?

Two balanced analogue audio outputs and two digital AES/EBU outputs are provided through XLR interfaces. Match the downstream equipment and signal format.

Which codecs can be decoded?

The technical table lists MPEG-1 Layer II, MPEG-2 AAC, AC-3, E-AC-3 and DRA. HE-AAC is not supported.

What audio sampling rates and gain range are specified?

The listed sampling rates are 44.1 and 48 kHz. Audio gain is adjustable from −24 to +12 dB.

Can the selected programmes be sent over IP?

Two SPTS outputs over UDP/RTP are specified, with unicast and multicast delivery, corresponding to the two decoded audio programmes.

Does the unit decrypt BISS or encrypted radio feeds?

BISS descrambling is not supported. An encrypted input must be decrypted by suitable external equipment before reception and decoding.

How is the unit managed?

Use the built-in Web GUI or front-panel LCD and buttons. Firmware upgrades are available through web management; SNMP is not supported.

Is redundant power included?

Dual hot-swappable redundant power supplies are standard on IRA-3000 and IRA-3000T. A single-power-supply configuration is available as an option.
