4. INTRODUCTION
DN44BOB is a digital interface for Dante® audio over IP protocol. Its main features are:
Ethernet interface.
Digital audio transmission and reception in Dante® format.
EclerNet compatibility.
4 balanced MIC/LINE inputs, phantom power and 3 levels of sensitivity, converted
to Dante® format and sent to the network.
4 balanced line outputs, converted from 4 Dante® channels fed by the network
Euroblock connectors for analogue audio inputs and outputs.
4 GPI ports (0-10VDC) on Euroblock connector.
4 GPO ports (NO/NC) on Euroblock connector.
To setup the DN44BOB, you have to use the EclerNet Manager*application. See the
EclerNet Manager Application manual for more information.
* The EclerNet Manager application is available for download from www.ecler.com
To setup Dante® transmission and reception channels, the Audinate® Dante Controller
application has to be used. See the EclerNet Manager Application manual for more
information.

5. INSTALLATION
5.1. AC connection and powering on
The audio interface is powered by alternating current (AC) through its external power
supply: 100-240 VAC, 50-60Hz.
The power supply must be correctly grounded (ground resistance, Rg = 30or less).
The operating environment should be dry and be totally free of dust. Do not expose the
unit to dripping or splashing. Do not place incandescent objects like candles on top of it.
If the device requires any intervention and/or connection/disconnection, it must
be powered off first. There are no user-serviceable parts within the unit.
To avoid buzzing, do not allow the power cable to intertwine with audio shielded cables.
5.2. Audio input connections
The DN44BOB rear panel provides 4 balanced analogue signal inputs labelled "IN" (7),
supporting line or mic levels. The input signal type selection and handling is managed
with EclerNet Manager Application. See the EclerNet Manager manual for more
information.
Signal inputs use 3-position screw terminal blocks. The wiring is as follows:
Hot or direct signal > + terminal
Cold or inverted signal > –terminal
Ground > terminal
For UNBALANCED connection, short circuit the terminal –to ground.

7
5.3. Audio output connections
The DN44BOB rear panel provides 4 balanced analogue line outputs labelled "OUT" (6).
Signal outputs use 3-position screw terminal
blocks. 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 –.
5.4. Ethernet / DANTE® port for programming and control
A RJ45 connector (11) allows to connect 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 to a DN44BOB unit.
Transmission and reception of 4 Dante® channels
Connection to WPmSCREEN units (remote control of an entire network of
EclerNet devices through custom UCP (User Control Panels), even from third-
party devices, Android®, iOS®, etc.)

8
5.5. GPI remote control ports
The DN44BOB rear panel provides 4 GPI inputs (9) for 0-10VDC continuous voltage
control. Each of these inputs can be connected to an external physical device
(potentiometer, contact closure, variable 0-10V voltage, etc.) and assigned to a
DN44BOB function, such as:
Remote volume control of an input or output channel by external Ecler WPm
series hardware like a WPmVOL potentiometer or a WPmVOL-IR remote control.
For muting and unmuting, use a contact closure instead of potentiometer.
Preset recall using a five-way selector, like a WPmVOL-SR
GPI connectors use 3-position screw terminal blocks. The wiring is as follows:
Positive, +10 VDC > + terminal
Variable voltage, 0-10VDC > –terminal
Ground > terminal
Connection examples
Connecting cables can be up to 500 meters long with a minimum section of 0,5 mm2.
Please consult your ECLER dealer or www.ecler.com about the WPm series remote
control wall panels.
5.6. GPO remote control ports
The DN44BOB rear panel provides 4 NO/NC (normally open/normally closed) relay
outputs (8). The open or closed status of each relay can be saved in a DN44BOB preset.
So loading a preset will restore the GPO status (open/closed) as it was when saved. It is
then possible to interact with external equipment such as motorized projection screens
or movable partitions, lights, sirens, GPI inputs of other equipment, etc.

6. FRONT PANEL LED INDICATORS
The DN44BOB front panel provides the following elements :
POWER LED indicator (5): lights up when the unit is on.
DANTE LED indicator (3):
oRed LED: Ethernet network disconnected.
oGreen LED: Ethernet network connected and device operating as master
(transmitting Dante® clock on the network).
oAmber LED: Ethernet network connected and device operating as slave
(synchronized with the clock of the Dante® Master unit on the network).
DATA LED indicator (3): off when there is no connection with EclerNet Manager
even if connected to Ethernet. Lit when connected to EclerNet Manager. Blinking
to indicate data traffic with EclerNet Manager or other.
Audio input (analogue) LED indicators (1): indicate the presence of an audio signal
at the unit inputs and its intensity level (green, amber and red colours which
correspond, in this order, to an increasing level of intensity).
Audio output (analogue) LED indicators (2): indicate the presence of an audio
signal at the unit outputs and its intensity level (green, amber and red colours
which correspond, in this order, to an increasing level of intensity).
7. LOCATION, SET UP, VENTILATION
DN44BOB has been especially designed to be installed in a standard 19" rack, taking up
1U (height) and only half the width. It includes the PUM3 adapter, which allows two
rack width media devices to be mounted on racks of 1 standard unit of measure (19”).
The DN44BOB being a heat generator, it should not be enclosed or exposed to extreme
temperatures.
If multiple amplifiers are installed in the same rack or in a cabinet with closed doors, it is
highly recommended to install fans in their upper and lower ends for a forced air flow
from the bottom up. This upward air flow will favour the dissipation of heat generated
inside.
8. CLEANING
The casing should not be cleaned with solvents or abrasive materials since they can
damage the screen printing. To clean the product, please used a cloth dampened with a
mild liquid detergent and water, and wipe it off with a dry and clean cloth. Be careful
that water never gets into the unit through its holes.
