About EtherSound

EtherSound is an audio networking protocol developed by Digigram in France. EtherSound allows up to 64 channels of uncom-

pressed 24 bit/48 kHz audio to be bi-directionally transferred – 64 channels downstream plus 64 channels upstream – over a

single CAT5e Ethernet cable. Up to 32 channels of 24 bit audio can be transferred when the sample rate is 96 kHz. Remote con-

trol signals for head ampliﬁers and other devices can be transferred simultaneously with the audio signals.

Signals can be transferred over distances of up to 100 meters* between devices. Even greater distances can be covered if media

converters are used to convert the signals to optical ﬁber format.

* Dependent on cable quality. Refer to the website listed below for details.

Latency when transferring 48 kHz signals is 5 samples (104µsec), increasing by 1.4 µsec for each device added to the network

(including network switches). EtherSound is the ideal choice for systems in which minimal latency is a priority.

The AVS-ESMonitor software application for Windows platforms that allows setup and monitoring of devices connected to an

EtherSound network is available from the AuviTran website at no charge.

The most basic type of connection used for EtherSound networks is the serial “Daisy Chain.” Daisy chain networks allow 64

channels of audio to be independently transferred in both the downstream and upstream directions simultaneously. In this case

the top device in the chain is the word clock master, known as the “Primary Master.”
