EtherSound Hardware ESmonitor Software

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)

12 Connectors Profesionnal Neutrik EtherCon Connectors

13 EtherNet Standard Hardware
Layer 2 (Data Link Layer) switches

14 Network Architectures

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

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

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

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

19 System 5: Conference hall Single network, several rooms

20 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)

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

22 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)

23 Analogue Link Microphone to cabinet ~4ms 2ms 2ms

24 EtherSound Link Microphone to Cabinet : ~2.4ms AD8HR with AVDKit ~1ms
ES base time = 125us Daisy chain (4us) + NX242 IN/OUT (84us) Daisy chain (4us) + Desk IN/OUT (168us) Amplifier IN (21us + DA ~1ms)
