Leading codec manufacturer Tieline has announced the new Gateway Multichannel IP audio codec is now available to purchase and will be shipping in December.

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 or 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 support for AES67, ST 2110-30, AES3 and analog I/O as standard.
“This is an exciting day for broadcasters and the culmination of many months of research, design and development,” said Will McLean, Tieline’s CEO. “Broadcasters these days want more functionality within a compact rackmount footprint, combined with simple connectivity and flexible remote control features. The new generation Gateway codec delivers best-in-class functionality and interoperability for IP streaming over WANs, as well as integration with AES67 and ST 2110-30 compatible networks.”
Gateway Replaces Merlin PLUS and Genie Distribution Codecs
Tieline Gateway is perfect for large-scale audio distribution as well as managing multiple incoming remotes at the studio. It will immediately replace and supersede the popular Merlin PLUS and Genie Distribution codecs by delivering more connection options, flexible scalability over time, as well as new IP technologies.

The Gateway seamlessly integrates with all Tieline IP codecs and delivers hitless packet switching using SmartStream PLUS redundant streaming, plus bandwidth aggregation using Fuse-IP technologies over internet connections. It supports 16 bidirectional mono or 8 bidirectional stereo streams of IP audio in 1RU to increase channel density and reduce rack space requirements.
Its feature-rich and compact design is interoperable with all Tieline IP codecs and compatible over SIP with all EBU N/ACIP Tech 3326 and 3368 compliant codecs and devices.

The Gateway has two standard versions. One supports 8 Channels in/out (8 Mono or 4 Stereo) and the other supports 16 Channels in/out (16 Mono or 8 Stereo). The codec also supports a flexible upgrade path that allows you to buy a Gateway with 8 channels and upgrade the codec over time as needs change or your network expands.
The Tieline Gateway interfaces with analog and AES/EBU sources, as well as newer broadcast plants with AES67 and ST 2110-30 IP audio infrastructure. An optional WheatNet-IP card will also be available.
Gateway is configurable through an embedded HTML5 Toolbox Web-GUI interface and is also fully controllable using Tieline’s Cloud Codec Controller.
