No IT !

An ES100 audio only system supports 64 audio channels

and a serial connection for the head amp control. No fur-

ther IP over Ethernet services can be integrated. The big

advantage of such a system is that the system does not

include any IT components. The network is built with a

number of ES100 devices and the same amount of cables.

Nothing else is required.

The ES100 devices in such a system can be connected in

any order, as long as OUT connectors are connected to IN

connectors - just as with analogue audio cabling.

Locations

For the user an ES100 audio only system includes loca-

tions and long distance cables.

A location can contain one ES100 device, or several ES100

devices daisy-chained with patch cables. It is good practise

to mechanically secure the patch cables in the i/o rack to

prevent intermittent connectivity problems in them. Patch

cables are not removed after every application, so they

don’t need to be time-managed.

Wordclock

The ES100 ring has to support any device to be the Pri-

mary Master. As the Primary Master is also the wordclock

source, an ES100 system can not sync to the outside world

as this would ﬁ x the position of the wordclock device - if

an emergency occurs and the Primary Master changes then

the device synced to the outside world will no longer be

syced to the ES100 ring. This is specially a problem in

broadcast applications, and in applications requiring more

than 64 channels - as multiple rings can not be synced

together.

Take-over

The ES100 redundancy protocol is very fast - the redun-

dant ring recovers form a failure almost immediately.

The synchronisation of the ES100 devices then take 2 to

3 seconds to resync before restoring the audio connec-

tions. When all devices in the ring support the ES100’s

‘emergency clock’ feature the re-synchronising is also

virtually seamless, resulting in an immediate recovery of

the system.

HA control

The ES100 protocol includes a low bandwidth serial

tunnel capable of supporting an RS422 connection. This

connection can be used to provide head amp control on

Yamaha mixing consoles with DME and AD8HR mic

pre-amps.
