Overview

AUE400 is a broadcasting-grade multi-channel audio encoder with high quality based on MPEG-2/DVB standard. It can simultaneously encode and Multiplex 4 mono-channels analog audio (or 2 channels stereo analog audio) , or 2 channels of AES/EBU audio, it has IP output and IP casting function, is able to output TS via E1 or ASI. The input audio interface supports analog and AES/EBU input. It can be managed and controlled via web browser. It features small size, light weight, high reliability and strong compatibility and convenient interconnection with other equipments.
