Tieline Gateway Multi Channel Codec










The Most Powerful DSP-Based 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 support for AES67, ST 2110-30, AES3 and analog I/O as standard.

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.

The gateway can be purchased in two forms, the TLR6200-8, 8 Mono or 4 Stereo and TLR6200-16, 16 Mono or 8 Stereo, the TLR6200-8 can be upgraded to have the full 16 Mono\ 8 Stereo Channels.
