Overview
GatesAir Intraplex IP Link 200N, Dual Bidirectional Stereo IP STL Codec
Offering an array of audio coding options along with IPConnect technology for data tunneling, the IP Link codecs are suitable for use in Studio to Transmitter Links (STLs) as well as audio contribution and distribution networks.
The IP Link 200n is ideal for STL applications requiring two separate stereo channels, and its support for IP multicast and multiple unicast streams enables one encoder to feed multiple decoders.
The Intraplex IP Link 200n audio codec was designed to provide unprecedented level of reliability from ground up. At the hardware level, the N+1 redundancy with built-in control for data switches provides automatic synchronization of configuration and switch-over capability. This reliability is further enhanced with an optional hot-standby power supply.
Features
