Product Overview

Ethernet Audio Transmission Unit

THE AOE AUDIO over ETHERNET NETWORK is an easy to use solution for transporting audio signals over Ethernet TCP/IP based local and wide area networks (LAN/WAN), as well as the Internet.

Ethernet Transport
The AOE is a bidirectional 2 channel audio transmission over TCP/IP LAN or WAN Ethernet network. Control of Local and remote equipment is possible using the built in eight programmable trigger inputs to initiate and terminate audio transmissions, eight programmable open collector control outputs as well as the RS-232 and RS-422 serial port for data transmission/reception.

Hi Fi
Long-distance digital transmission of balanced analogue audio signal is possible without electro-magnetic interference, signal loss or distortion.  High quality uncompressed 24bit digital audio at 48kHz transmitted over TCP/IP network with a S / N better than 85dB, THD less than 0.01.

Power Backup
Simultaneous support of AC and DC power offering un-interrupted broadcast with emergency battery back up in the event of a power outage.

Easy to Use
Monitoring of input and output signals as well as network status via the front panel LED indicators. Monitoring of the audio signal is made possible using the front panel mounted headphone output jack

Browser Configuration
Easy to use browser based software allows for user system monitoring and control of the transmission matrix. System Security prevents non-administrator users to tamper with the equipment operation and prevent malfunction. Equipment operation history is stored in a log file to check the operating status of the equipment, and equipment malfunction traceability making it easy to identify system faults.


Firmware can be downloaded directly from InterM here.


Applications include campus wide paging or messaging, background music, audio distribution for airports, railway stations, ground transportation, and anywhere audio required to be transported easily over long distances.
