Tieline GATEWAY-8
The Highest Density DSP-based 1RU IP Audio Codec
The Tieline Gateway-8 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 and speaks the language of AES67, ST 2110-30, ST 2022-7, RAVENNA, Livewire+, NMOS, Ember+, AES3 and analog I/O as standard. An optional WheatNet-IP card can also be installed at purchase.
Overview
The Most Powerful DSP-Based 1RU IP Codec
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, ST 2110-30, ST 2022-7, Livewire+, RAVENNA, NMOS, and Ember+. An optional WheatNet-IP 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.
