Description
AXT8709 network four-channel audio output terminal is a TCP/IP based full digital analog-digital conversion signal processor, with dual network redundancy design and may be deployed anywhere with network access.   
This device allows output of audio signals from remote audio streaming media under intelligent control of the controller;  the device provides one emergency audio input port for connection to emergency signals from fire control center and another emergency audio output port for connection to emergency amplifier;the device does not require any local operation and can work after properly configured via management software.
