Tieline Bridge IT PRO

Tieline Bridge-IT PRO – 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 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)As an IP audio pioneer, Tieline has built up many years of knowledge and expertise in broadcasting audio over unmanaged IP networks like the internet. 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 cell phone networks and the internet, especially in those situations when Quality of Service (QoS) is unavailable. Some other manufacturers charge thousands of dollars for IP management 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 dynamic jitter buffering, forward error correction and packet repair, deliver continuous high-quality audio over both managed networks and the open Internet. Bridge-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.711and 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. Compare Bridge-IT’s superior programming functionality and simple user interface with other inexpensive codecs. Don’t forget that Bridge-IT:
    • Features front panel navigation, LCD display, PPM metering and dialling keypad.
    • The comprehensive Toolbox web-browser GUI control interface (Java and HTML versions now available).
    • Has broadcast XLR connectors, simultaneous analog and digital audio in/outs, plus a huge range of algorithms – including Opus as standard.
    • Is IPv4/v6 and EBU N/ACIP Tech 3326 compatible over IP and will connect to any SIP-enabled IP codec brand.
    • Has had reliable automated SD card backup (since 2009), unlike some other competing products! 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 comes standard with 16 Bit 22kHz uncompressed linear audio, as well as Opus, MPEG Layer 2, AAC-LD, AAC-ELD, LC-AAC, HE-AAC v.1 and HE-AAC v.2, G.711, G.722 and Tieline Music and MusicPLUS. Music PLUS delivers 22 kHz mono and stereo with a 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.

    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.
