IP Audio Applications

Bridge-IT XTRA is capable of transporting audio streams reliably, simply and effectively over IP data networks such as wired and wireless LANs, WANs, the internet, satellite IP, Wi-MAX and Wi-Fi. It is perfect for:

  • Studio-to-Transmitter Link (STL) applications
  • Studio-to-Studio Links
  • IP Multi-unicasting
  • IP multicasting on compatible IP networks
  • Simple remote broadcast links

Affordable IP Audio

Bridge-IT XTRA is inexpensive and allows broadcasters to expand their IP network at a fraction of the cost of competing IP codecs without compromising on broadcast quality features. Unlike most low cost IP audio codecs, Bridge-IT XTRA has all the broadcast input connectors you would expect on a full-featured codec. Simultaneous analog and digital AES/EBU audio outputs are provided on XLR connectors and it includes front and rear panel ¼” (6.35mm) stereo headphone outputs.

Simple to use...

Compare Bridge-IT XTRA’s superior programming functionality and simple user interface with other low cost 1RU codecs. Bridge-IT XTRA features a full hardware front panel interface including navigation buttons, LCD display, PPM metering and dialing key pad. It can also be configured and controlled remotely using the Toolbox web-GUI interface.

Broadcast Multiple Connections

Multicast stereo audio over compatible networks to unlimited end-points, or send up to 6 stereo multi-unicast audio streams over WANs like the internet.


Bridge-IT XTRA comes with 16 or 24bit, 48kHz linear audio for crystal clear, low-latency uncompressed sound. Standard broadcast algorithms available include:

  • Opus
  • AAC-LC and AAC-HE v.1 and v.2
  • aptX® Enhanced
  • MPEG Layer 2
  • Tieline Music (15kHz)
  • Tieline MusicPLUS (22kHz) which delivers stereo audio with 20 ms encode delay at 96Kbps, offering huge savings on your data bills.
  • G.711 (u-law and a-law) G.722
  • MP3 playback from an SD/SDHC card


Bridge-IT XTRA will connect to any SIP-enabled IP codec brand with industry standard algorithms like Opus, AAC-LC, AAC-HE, AAC-LD, AAC-ELD, MPEG Layer 2, G.711 & G.722. Bridge-IT XTRA is also EBU N/ACIP Tech 3326 compatible using SIP for connecting to other codec brands and devices. It is also internet/satellite streaming and HD radio compatible.

Audio Backup

Insert an SD/SDHC card with MP3 or linear backup audio and Bridge-IT XTRA will automatically play out the audio if your IP service fails.

Remote Control Interfaces

4 control inputs and outputs (DB-15) are provided and the ToolBox web-GUI enables custom control of relay functionality and ancillary RS232 data connections.
