Tieline Gateway 4 – New Generation 4 Channel IP Audio Codec
The Tieline Gateway 4 is a powerful DSP-based 1RU IP codec designed for live remote broadcasting applications, Studio-to-Transmitter Links (STL), and Studio-to-Studio Links (SSL). It supports up to 4 mono or 2 stereo connections across the public internet or any QoS-enabled IP network, including T1 and T3 connections and private WANs with MPLS. The Gateway 4 is compatible with AES67, ST 2110-30, ST 2022-7, RAVENNA, Livewire+, NMOS, Ember+, AES3, and analog I/O as standard. An optional WheatNet-IP or Dante card can also be installed at purchase.
Overview:
The new generation Tieline Gateway 4 delivers best-in-class DSP-based reliability and performance for mission-critical broadcast streaming applications. It is ideal for:
- Remote broadcast applications
- Studio-to-Transmitter Links (STLs)
- Studio-to-Studio Links (SSLs)
The Gateway 4 is designed for solutions requiring up to 4 audio streaming channels with advanced redundancy features and remote configuration and control. It supports 4 full-duplex audio channels in 1RU and is backward compatible with all Tieline IP codecs. The Gateway 4 provides two stereo connections, or one stereo and two mono connections, or up to 4 mono connections.
