Note: These operations require opening of the cabinet and shall be done
by qualified personnel only.
Setting the EtherSound channels (ES220 and
ES220-L)
Four decimal rotary switches on the EtherSound board inside the device
determine whether the assignment of the EtherSound channels to the inputs
or outputs of ES220(-L) is done locally or remotely by configuration software.
(
to modify this setting, see appendix B
).
By default, the devices are parameterized for software control (factory setting).
Input/Output configuration (ES220-L only)
On ES220-L, a jumper makes it possible to parameterize whether the
equipment adds two channels to the network EtherSound (
Master
) or restores
two channels (
Slave
); for more details, please refer to appendix E of this
manual).
By default, the devices are parameterized in order to restore two channels
from the network (Slave).
Nominal input level
The nominal input level can be configured via internal jumpers. The default
value is + 4 dBu, it can be set to -10 dBu (f
or more details, please refer to

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.
Note: 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.
