Excellence in Broadcast

Tieline Bridge-IT XTRA

Overview

The 1RU Bridge-IT XTRA is a cost effective, high-performance, point-to- point and multi-point stereo IP audio codec with all the features of the Bridge-IT IP codec and more!

Bridge-IT XTRA includes dual power supplies, front and rear panel stereo headphone sockets, 4 GPIO in/outs and aptX® Enhanced as standard. It also includes SD/SDHC card audio backup.

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.

SmartStream PLUS: Rock Solid Audio using Inexpensive IP Links

As an IP audio pioneer, Tieline was the first major codec manufacturer to integrate SmartStream features such as Automated Jitter Buffer management, Forward Error Correction (FEC) and error concealment techniques in all IP codecs. These features dynamically respond to variable conditions over unmanaged IP networks like the public internet to ensure reliable streaming.

Now SmartStream PLUS has revolutionised IP broadcasting by delivering the rock solid and reliable STL-grade audio quality using inexpensive unmanaged IP networks like the internet for remotes and nailed up links. Some other manufacturer's charge thousands of dollars for IP managment software as if it's an optional extra. Tieline believes high performance and rock-solid reliability is an essential part of each and every broadcast and delivers its renowned SmartStream IP management software for free.

Algorithms

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
  • AAC-LD, AAC-ELD
  • 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

Compatibility

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.
