Overview

AUE1200 is a broadcasting-grade multi-channel audio encoder with high quality based on MPEG-2/DVB standard. It can simultaneously encode and Multiplex 12 single-channels analog audio (or 6 channel analog stereo audio), or 6 channels AES/EBU audio, it has IP output and casting function, and be able to output TS via E1, ASI. The input audio interface support analog input, AES/EBU input. User can manage and control via web browser. It features modular structure, small size, light weight, high reliability, strong compatibility and convenient interconnection with other equipment.
