Bridge-IT for inexpensive IP audio solutions…  

Expand your 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.


Bridge-IT is perfect for:

  • Studio-to-Transmitter Link (STL) applications

  • Studio-to-Studio Link (SSL) applications

  • Point-to-Point IP audio distribution

  • Multi-point IP audio distribution 

  • Simple mono and stereo 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)

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.

   --- SmartStream PLUS logo

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. 

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 and loads of features…

------------ Danny Lipford

Bridge-IT is cost-effective and produced a quality broadcast for our audience and fans.  We definitely made the right choice for our show and appreciate all of the help from the team at Tieline.

“Today’s Homeowner” Radio Show

Compare Bridge-IT’s superior programming functionality and simple user interface with other inexpensive codecs. Don't forget that Bridge-IT includes:

  • Front panel navigation, LCD display, PPM metering and dialing key pad.

  • The comprehensive HTML5 Toolbox web-browser GUI control interface.

  • Broadcast XLR connectors, simultaneous analog and digital audio in/outs, plus a huge range of algorithms - including Opus as standard.

  • IPv4/v6 and EBU N/ACIP Tech 3326 compatibility over IP and will connect to any SIP-enabled IP codec brand.

  • Reliable automated SD card backup (since 2009), unlike some other competing products!

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

Huge choice of standard algorithms...

Bridge-IT comes standard with 16 Bit 22kHz uncompressed linear audio, as well as Opus, MPEG Layer 2AAC-LD, AAC-ELD, LC-AAC, HE-AAC v.1 and HE-AAC v.2G.711, G.722 and Tieline Music and MusicPLUS. Music PLUS delivers 22 kHz mono and stereo with 20ms encode delay at under100 Kbps, offering huge savings on your IP data bills and outstanding audio quality. HE-AAC v.2 is capable of delivering high fidelity stereo IP audio at bit-rates as low as 24Kbps. Optional aptX Enhanced encoding is also available for extremely low delay connections.

Automatic SD Card Backup…

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