EtherSound Network

Overview

EtherSound

High quality bi-directional audio Network. 2 x 64 channels 24bit/48kHz. Very low latency transmission. Standard Ethernet Hardware. Up to 65000 connected devices. Bi-directional status & Control data.

EtherSound Technology

Compliant to Ethernet IEEE 802.3 frame format.

It is full-duplex LANs with a bandwidth of 100Mbps. Audio channel synchronization is based on

valid EtherSound frame arrival. Each frame is transmitted at a defined sampling frequency (48kHz).

EtherSound Networks For Fixed Installations

Background/foreground music and live announcements; multi-zone audio distribution.

Point-to-point signal transfer over long distances.

Lower installation costs than analog systems,standard Ethernet cabling, daisy-chain architecture, competitive cost per network node.

Increased flexibility for system re-configuration.

EtherSound Networks for Live Sound

Audio distribution for mobile installations. Latency issues. Low cost cabling. Quick and easy system set up using

shielded CAT5e Ethernet cables. High-quality audio (24bit/48kHz).

EtherSound Implementation

Cabling

Cat5e, 6, 7 cabling, Shielded or Foil (FTP, ScTP). Stranded or Solid.

No UTP (unshielded) cabling Crossover cable for linking Laptop to

primary master.

Cabling

Cable length ranging from 90m(295ft) to 110m lengths (according to cable quality, number of passive connection…)

Fiber optic cables and Ethernet standard allow for segments up to 2 km(1.24mi)
