About this Guide
In recent years, several network technologies have emerged for centralized
management and control of large scale audio installations. This guide focuses on
EtherSound, a digital audio transmission protocol developed by Digigram of France.
Using a single CAT5e cable, up to 64 channels of audio may be transmitted in both
directions. Compliant with IEEE802.3 (100Base-TX), EtherSound networks can travel
through infrastructure made with widely available, low cost, Ethernet computer
switches and cables at a much lower cost than traditional analog installations.
Latency, 104 μ seconds plus 1.4 μ seconds per additional EtherSound device or
approximately 20 μ seconds per network switch on the signal path, is held to a
minimum, and is a major reason why EtherSound is receiving increasing acceptance in
Sound Reinforcement applications where monitoring delays are critical.
In this document, "EtherSound Setup Guide", configuration of networks using Yamaha
EtherSound products and procedures for utilizing the capabilities of EtherSound
technology to the fullest are presented.
