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)

Connectors Profesionnal Neutrik EtherCon Connectors

Network Architectures

System 1 : Small Venue Small analogue system, EtherSound out patches, budget sensitive desk

System 2 : Small Installations Additionnal Signal Processing, PA remote control through NX242

System 3: Large Installations One network for remote inputs, One network for diffusion

System 4: Live Multi console application, remote inputs on High quality AD, remote of the PA through NX242

System 5: Conference hall Single network, several rooms

Latency & Live Sound Lowest Lantency possible needed for monitor application (ear monitors on vocals, drum fill, wedge monitor). <5ms Max. DA PROCESSING 0.5ms AD NETWORK (0.125ms)

Latency & Live Sound Directivity control implies complete synchronisation –few microsec. Max.- 2us between the boxes

Latency times Base Latency 125usec (6 samples) Daisy chain Latency per module 1.4usec Switch latency : 21usec (1 sample) NX242 use in Master/Slave (4 samples) Re-synchronisation up to 1/256 sample in the NX242.(prevision 1Q-2005)
