Gateway Multichannel IP Codec


The Most Powerful DSP-Based 1RU IP Codec

The Tieline Gateway is the most powerful DSP-based 1RU IP codec enabling transport of multiple channels of mono or stereo audio across the public internet and any QoS-enabled IP network, including T1 and T3 connections and private WANs with MPLS. The Gateway streams up to 16 IP audio channels with native support for AES67, ST 2110-30, ST 2022-7, RAVENNA, Livewire+, NMOS, and Ember+, as well as AES3 and analog I/O as standard.

A New Era in Broadcasting…

The Tieline Gateway introduces a new era in high-density multichannel IP codec streaming. The Gateway supports up to 16 mono channels or 8 stereo streams of bidirectional IP audio in 1RU to increase efficiency and reduce rack space requirements. It interfaces easily with legacy analog and AES/EBU digital sources, as well as newer broadcast plants with AES67 and ST 2110-30 IP audio infrastructure. An optional WheatNet-IP card or Dante card is also available.

The Gateway is perfect for large-scale audio distribution to single or multiple locations, as well as managing multiple incoming remotes at the studio using SmartStream PLUS redundant IP streaming and Fuse-IP data aggregation technologies over internet connections. It is interoperable with all Tieline IP codecs and compatible over SIP with all EBU N/ACIP Tech 3326, 3347 and 3368 compliant codecs and devices like those from Comrex, Telos, and many more.


The Gateway is perfect for STL, SSL and audio distribution applications, with support for multicasting and multiple unicasting technologies. It is also perfect for managing multiple incoming remotes at the studio and can simultaneously connect to up to 16 hardware codecs or Report-IT Enterprise smartphone app users. Use for:

* Studio-To-Transmitter Links (STL)

* Studio-To-Studio Links (SSL)

* Audio Distribution

* Managing multiple incoming remotes at the studio

The codec also supports a flexible upgrade path that allows you to buy a base model Gateway 8 with 8 channels and upgrade the codec over time as needs change, or your network expands.
