Thank you for purchasing Digigram EtherSound ES220(-L)!
EtherSound ES220 and ES220-L are Digigram products
incorporating the EtherSound technology. They allow to easily and
economically insert into an EtherSound network or extract two
digital audio channels (2 + 2 in the case of ES220) from it, using
standard Ethernet components (CAT5 cables and switches).
ES220 converts two analog audio signals into two EtherSound
channels and two EtherSound channels into analog audio signals,
while ES220-L is configurable via jumpers: it either converts two
analog audio channels into digital audio and inserts them into an
EtherSound network, or it extracts two digital channels from the
network to convert them into analog audio signals. Both feature
GPIOs and take advantage of EtherSound's simple, nearly instant
set-up.
EtherSound ES220 and ES220-L allow audio distribution with a
flexibility going well beyond the possibilities of analog audio
installations. Routing can be adapted remotely to the changing
needs of the audio installation.
For more information on the EtherSound technology we invite you to
visit our web site where several documents (in English) are available
for download.
INFORMATION FOR THE USER
This equipment has been tested and found to comply with the limits for a
CLASS B digital device, pursuant to Part 15 of the FCC Rules and with the
following European and international Standards for:
Electrical safety: Elecromagnetic compatibility:
Europe: EN60950, 3rd edition
European Directive 73/23/CEE
“Low Voltage Directive”
International: EN60950, 3rd edition
Europe : EN55022:1998 + A1:2000, Class B /
EN55024: 1998 + A1:2001
European Directive 89/336/CEE on electromagnetic
compatibility
International: CISPR22:1997 + A1:2000 CLASS B
United States: FCC Rules-Part 15-Class B

In order to guarantee compliance with the above standards in an installation, the
following must be done:
• the provided cables must not be modified.
• additional cables used must have their respective shield connected to each
extremity.
Operation is subject to the following two conditions: (1) This device may not cause
harmful interference, and (2) This device must accept any interference received,
including interference that may cause undesired operation.
If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
* reorient or relocate the receiving antenna
* increase the separation between the equipment and the receiver
* connect the equipment into an outlet on a circuit different from that of the receiver
* consult the dealer or an experienced audio television technician.
Note: Connecting this device to peripheral devices that do not comply with CLASS B
requirements or using an unshielded peripheral data cable could also result in
harmful interference to radio or television reception. The user is cautioned
that any changes or modifications not expressly approved by the party
responsible for compliance could void the user’s authority to operate this
equipment. To ensure that the use of this product does not contribute to
interference, it is necessary to use shielded I/O cables.

1. Audio connectors
On ES220, a Sub-D 15 connector is used to input two balanced analog signals
and to output two balanced analog signals.
On ES220-L, only one of these two functions is accessible depending on the
configuration selected (for connector pinout see appendix C).
2. Network connectors
These two EtherCon
TM
NeutrikTM RJ45 connectors allow for a steady and
reliable connection to the EtherSound network. The “IN” port allows
connecting the ES220 to the equipment upstream, while the “OUT” port
allows connecting the ES220 to the equipment downstream. When an ES220
receives a descending stream on its “IN” port, it transmits it to its “OUT” port,
after - if required - having injected two EtherSound channels (if this device is
not the last element of the EtherSound chain). When an ES220 receives an
ascending stream on its “OUT” port, it transmits it to its “IN” port, after - if
required - having injected two EtherSound channels (if this device is not the
Primary Master). For more details, see the document “EtherSound Overview”
(available on our Web site).
3. GPIO connector
This connector allows setup of external control and monitoring devices
through configurable and protected General Purpose Inputs and Outputs. See
appendix D dedicated to the GPIOs for more details.
Note: the GPIO port is managed by configuration software only.
4. Power supply connector
4-pin Mini DIN connector (for the connector pinout see it appendix G).

INSTALLATION
Before mounting devices in a rack…
Internal settings
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 (for more details, please refer to
appendix E of this manual).
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.
