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

Ethernet Transport
Bi-directional 2 channel audio transmission over TCP/IP LAN or WAN ethernet network. Con-
trol of local and remote equipment is possible using the built-in eight programmable trigger
inputs to initiate and terminate audio transmissions, 8 programmable open connector control
outputs as well as the RS-232 and RS-422 serial port for data transmission/reception.
Hi-Fi Audio
Long-distance digital transmission of balanced analogue audio signal without electro-magnetic in-
terference, signal loss or distortion. High quality uncompressed 24bit digital audio at 48kHz transmi-
tion over TCP/IP network with a S/N better than 85dB, THD less than 0.01.

Software support
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 equip-
ment, and equipment malfunction traceability making it easy to identify system faults.
