Doteck AEN series Analog Audio Encoder

1 Introduction

Doteck AEN series is a broadcasting-grade multi-channel audio encoder with high quality based on MPEG-2/DVB standard. It can simultaneously encode /Multiplex 4 single- channel (or 2 dual-channel) Audio signal, and output TS via E1/ASI. The input audio interface supports analog and AES/EBU input. It can be managed and controlled via web browser. It is small size?light weight?high reliability?and strong compatibility and convenient interconnection between equipments.
