4. EtherSound Network
Overview

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

6. EtherSound Technology
Compliant to Ethernet IEEE 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).

7. 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.

8. 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).

9. EtherSound Implementation

10. 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.

11. 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)
