Bridge-IT for inexpensive IP audio solutions…   --------- PICK HIT AWARD --------- COOL STUFF AWARD

Tieline’s Bridge-IT is the ultimate affordable, high-performance, stereo IP audio codec solution for broadcast and professional applications. Designed to deliver point-to-point or multi-point connections, Bridge-IT transports audio streams reliably, simply and effectively over a range of managed and unmanaged wired and wireless* IP data networks, such as LANs, WANs and the internet.

Bridge-IT allows radio and television broadcasters to expand their IP network at a fraction of the cost of competing IP codecs, without compromising on quality or broadcast quality features. Multi-unicast in stereo to up to 6 different end-points from a single codec and reduce capital expenditure across your broadcast network.

Hear the Tieline SmartStream Difference...

--------- SmartStream logoAs an IP audio pioneer, Tieline has built up many years of knowledge and expertise in broadcasting audio over unmanaged IP Networks like the internet. Now SmartStream IP technology takes broadcasting over unmanaged IP audio networks to the next level for uncompromised AoIP.

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.

Tieline's exclusive and proprietary SmartStream IP technology responds to variable IP network conditions with agility and flexibility to significantly improve connection reliability over lossy IP networks such as 3G cell-phone networks and the internet, especially in those situations when Quality of Service (QoS) is unavailable.

Flexibility and Compatibility...

 ------ EBU NACIP logoBridge-IT is IPv4/v6 and EBU N/ACIP Tech 3326 compatible over IP and will connect to any SIP-enabled IP codec brand with industry standard algorithms, as well as VoIP devices supporting G.711 and G.722. Bridge-IT is also internet/satellite streaming and HD and digital radio compatible. 

It is designed for desktop use or two units can be installed side-by-side in a purpose-built 1RU mounting bracket.

Simple to use…

Compare Bridge-IT’s superior programming functionality and simple user interface with other inexpensive codecs. Bridge-IT features a full hardware front panel interface including navigation, LCD display, PPM metering and dialing key pad. It can also be configured and controlled remotely using the Toolbox web-GUI interface, which can be launched from the codec using a web-browser.


Bridge-IT is perfect for a large range of broadcast and professional applications that include:

  • Studio-to-Transmitter Link (STL) applications
  • Studio-to-Studio Link (SSL) applications
  • Point-to-Point IP audio distribution
  • Multi-point IP audio distribution 
  • Simple remote broadcast links
  • Cable Head End IP Audio Distribution
  • Low-latency audio over IP bridging solutions
  • Multiple codec installations (2 codecs fit in 1 x 19” rack unit)

Bridge-IT Purchase options...

Bridge-IT comes as a basic hardware and software pack or a pro version hardware and software pack, which includes AAC algorithms and multi-unicasting.

aptX® Enhanced audio coding is also available as an additional option.

Broadcast Quality Connectors

Unlike most affordable IP audio codecs, Bridge-IT has all the broadcast 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 a ¼” (6.35mm) stereo headphone output.

--------- Bridge-IT - rear panel description

Simple non-technical IP connections and Onboard Audio Backup

Bridge-IT is the first inexpensive IP audio codec to offer 3 different ways to connect over IP.

  1. For a simple permanent point-to-point encoder and decoder, Bridge-IT lets you connect without using a computer. Simply dial the IP address of the remote codec using the front panel keypad and LCD screen.
  2. Bridge-IT serves up a comprehensive graphical user interface in a standard web browser. Just type the IP address of your codec into your web browser to start remote control, configuration and dialing.

Encode with a range of standard algorithms or optional AAC and aptX Enhanced Algorithms...

Bridge-IT comes with 16 Bit 22kHz uncompressed linear audio at less than 12 ms encode delay, as well as MPEG Layer 2, G.711, G.722 and Tieline Music. Tieline MusicPLUS is also standard and provides 22 kHz mono and stereo with 20ms encode delay at under100 Kbps, offering huge savings on your IP data bills and outstanding audio quality. LC-AAC, HE-AAC v.1 and HE-AAC v.2 decoders are also included as standard.

Upgrade your Bridge-IT audio codecs today by purchasing and installing the optional AAC encode software licence and you will instantly have the ability to encode LC-AAC, HE-AAC v.1 and HE-AAC v.2 algorithms. HE-AAC v.2 is capable of delivering high fidelity stereo IP audio at bit-rates as low as 24Kbps. aptX Enhanced audio coding is also available for extremely low delay STLs and Audio Distribution.

Automatic IP network management and failover…

Tieline’s SmartStream IP technology manages the IP connection between two points using dynamic jitter buffering, forward error correction and packet repair, to deliver continuous high quality audio over both managed networks and the open Internet.

In case your IP link fails Bridge-IT also has an SD/SDHC card slot which can be pre-loaded with MP3 audio for automatic failover to backup recorded audio. Bridge-IT's onboard relay control ports can also be programmed to notify you of a failure via any third party relay-enabled hardware.
