INSTALLATION

Before mounting devices in a rack...

Internal settings

On ES881, ES1241, and ES16161 the local sampling frequency is switchable by means of a jumper between
44.1 kHz and 48 kHz.
Preset default value is 48 kHz.
In case you need to change the default setting, please refer to appendix B of this manual.
Note: These operations require opening of the cabinet and shall be done by qualified personnel only.

Connecting your EtherSound device

It is recommended to establish all connections before powering up the device.

Power supply

Before plugging the power cord, make sure that:
•
the power cord is not damaged
•
the AC outlet used is properly earthed.
Just like for any other audio system, power the individual devices up following the audio path and power
down in the opposite direction.
Do not allow anything to rest on the power cable. Keep the power cable away from where people could trip
over it.

Network

The cable type most commonly used today is CAT5e. For more detailed information, please refer to the
document "Building ES Networks", available on the enclosed CD-ROM and on our web site.
The network connections are established via two Neutrik
easy: use the connector labeled "IN" to connect the descending EtherSound stream (downstream, coming from
the 'Primary Master'), the connector labeled "OUT" to connect the ascending EtherSound stream ('upstream').

from the device, press the latch, then withdraw the cable while maintaining the latch pushed.

Example 1: bi-directional point-to-point transmission of eight audio channels

This application is very easy with EtherSound ES881, ES1241, and ES16161.
Connect a standard Ethernet cable between the "OUT" port of the first Ethernet bridge to the "IN" port of the
second Ethernet bridge. Bring into line the EtherSound channels on the two devices (see the on-line help of
the configuration software).

Example 2: more complex architectures

System topology may be daisy chain, star, or a combination of both. By default, the first device in a network,
such as an EtherSound ES881, provides the master clock for the entire network. Nevertheless, you have the
possibility to synchronize the 'Primary Master' on an external clock by using the 'Word Clock In' input and by
then providing this clock to the EtherSound bridges downstream from the 'Primary Master' passing through
the 'Word Clock Out' outputs.
Connect the "OUT" port with the "IN" port of the following EtherSound device.
Repeat this step for each device in the network. The maximum distance between two devices is 100 meters
(328 feet). Intermediate switches or fiber optic links may be used to considerably increase this distance.
