AXIA Livewire

Today we can confidently say that for several years to complete the transition studios from analog to digital storage, mixing, processing and distribution of audio signals. So today should be have a method of switching, which would make it easy, efficient, flexible and cheap. The company Telos Systems (USA) in search of such technologies looked at the world of computers and telephones. This gave the opportunity to take advantage of all variety of products and achievements in these sectors in the field of audio. When using Ethernet is a lot of sense. Ethernet allows to combine several channels of digital audio and ancillary data and transmit them over a single cable. These data can be quite simple, such as command from the audio player, or such as file transfer, electronic mail, web communications, etc. For sound transmission in Ethernet environment Telos Systems company at the beginning of the XXI century has developed special protocol, which today is dreaming, perhaps, every station technical director, Livewire.

It allows you to transmit real-time audio-related data (PAD) and control signals devices via Ethernet. Simultaneously, the same network can be used to send messages of individual files and other information. In the network Livewire audio is not compressed using RSMkodirovanie 48 kHz/24 bit, and the terminals are dynamic range greater than 100 dB, THD of less than 0.005% and headroom to +24 dBu. Livewire protocol allows you to transfer up to 25 stereo 100BaseT network and up to 250 stereo signals in both directions for Ethernet-channel and with speed of 1 Gb / sec. May apply different physical environment TCP / IP, including optical communication channel using appropriate media converters. Cascading encoders and network capacity provided by managed switches in the third level, which can transmit data to control the EM-processor, RDS-encoder, transmitter, and so on. To us familiar analog or digital audio snared Livewire, a equipment AXIA (the company is part of the TLS CORP). The whole system is designed to build AXIA radio stations of all sizes for Ethernet-based network. In the matter of signal we are interested in the hardware units of the system AXIA so-called "nodes" that are the interface between analog and digital audio and network Livewire.
