- AXT8709
- Four Channel Rack-Mounted Network Terminal
● It adopts a dual network redundancy design and is capable of working on different network segments.
● It may be deployed anywhere with network access.
● It supports a maximum 48 kHz sampling rate and 16-bit digital audio stream decoding.
● 10M/100M adaptive networking
● The device provides DC 24V/100MA output and short-circuits output under simultaneous control.
● It can play the background music, emergency calls, and warning signals from the system controller
● The device provides one EMC audio input and one EMC audio output.
● Audio Terminal Local volume is controllable.
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. The AXT8709 4-channel network audio terminal is a network fully digital analog-digital conversion signal processor based on TCP/IP transmission protocol, which adopts the dual network interface redundancy design, and can be coupled at any place with access to network. The remote audio data stream can output the audio signal through the machine with intelligent control of the host machine; one emergency audio input interface is used to connect the emergency signal of the fire center, and one emergency audio output interface is used to connect the emergency power amplifier; local control is not required, and it can be used after remote configuration through the management software.
