5. INSTALLATION

5.1. Location, set up, ventilation

The PLAYER DUO-NET has been especially designed to be installed in a standard 19"
rack, taking up 1U.

In professional installations it is highly recommended to locate the device in the same
rack as the sound sources.

Since its power consumption is very low, forced ventilation is not necessary. However,
avoid exposing the device to extreme temperature and the environment in which it is
placed should be as dry and clean (no dust) as possible

6

5.2. AC connection and powering on

DUO-NET is powered by alternating current through its external power supply: 100­240 VAC and 50-60 Hz. This external PSU has interchangeable connectors: American,
European, British and Chinese.

The work environment must be dry and completely free of dust. Do not expose the
appliance to falling water or splashes. Do not place objects with liquid or naked flame
sources, such as candles, on top.

If any intervention and / or connection-disconnection is required, the power must be
disconnected previously. Inside the device there are no manipulable elements by the
user. The power cable must not be mixed with the audio cables, as this could cause
buzzing.

5.3. Audio output connections

The DUO-NET PLAYER features 2 separate balanced stereo outputs (one for each
player) on the rear panel.

Signal outputs use 3-position screw terminal blocks (Euroblocks). The wiring is as
follows:

 Hot or direct signal > Terminal +
 Cold or inverted signal > Terminal -
 Ground > Terminal 

For unbalanced connection, don't connect the terminal -.

7

5.4. ETHERNET port for programming and control

A RJ45 connector (13) allows connecting the device to an Ethernet network:

 Management from the EclerNet Manager application. See the EclerNet Manager

Application manual for more information.

 Direct connection (point-to-point) of a computer/WPmSCREEN unit to a DUO-

NET PLAYER unit.

 One or more DUO-NET units and other EclerNet devices can be connected to a

computer and one or more WPmSCREEN units in order to create an EclerNet
project through an Ethernet network composed of one or more Ethernet switches
and Ethernet network cabling.

 Connecting to third party devices for remote management and integration to other

electronic systems (Crestron, AMX, Vity, Medialon, etc. Trademarks registered by
their manufacturers). Used protocol: Ecler TP-NET. Refer to the TP-NET protocol
manual for more information.

5.5. GPI remote control ports

The rear panel of the DUO-NET PLAYER offers 4 GPI inputs (14) for 0-10VDC
continuous voltage control. Each of these inputs can be connected to an external
physical device (contact closure, switch, sensor, etc.) and assigned to a DUO-NET
PLAYER function, such as:

 MUTE or SOLO On/Off using a switch or contact closure
 Recalling a preset using a switch or contact closure
 Triggering pre-recorded messages with or without priority
 Etc.

GPI connectors use 3-position screw terminal blocks (Euroblocks). The wiring is as
follows:

 Power > Terminal +
 GPI terminal > Terminal 1, 2, 3 or 4
 Ground > Terminal 
