Graphic Symbol Explanation
The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert
the user to the presence of uninsulated “dangerous voltage” within the product’s
enclosure that may be of sufficient magnitude to constitute a risk of electric shock to
persons.
The exclamation point within an equilateral triangle is intended to alert the user to the
presence of important operating and maintenance (servicing) instructions in the literature
accompanying the appliance.
The lightning f lashes printed next to t he output terminals are intended t o alert the user to
the risk of hazardous energy. Output c onnectors that could pose a risk are marked with
the lightning f lash. Do not touch output terminals while apparatus power is on. Make all
connections with apparatus turned off.
WARNING: T o pr event elect r ic s hock or fire hazard, do not expose this equipment to rain or moisture.

1. IMPORTANT NOTE
Thank you for putting your trust in us and for having chosen our Dante® audio digital inter face
DN44BOB. It is VERY IMPORTANT to carefully read this manual and to fully understand its contents
before any connection in order to maximize your use and get the best per formance from t his equipment.
In order to guarantee the optimum operation of this unit, we strongly recommend that its
maintenance is carried out by our Authorized Technical Services.
DN44BOB is guaranteed f or 3 years.
1.1. Precautions
Do not expose the unit to dripping or splashing, do not place liquid containers or incandescent
objects like candles on top of it.
If the unit requires any intervention and/or connection/disconnection, it must be powered off
first.
There are no user-serviceable parts within the unit.
2. INTRODUCTION
DN44BOB is a digital interface for Dante® audio over I P protocol. Its main features are:
• Ethernet interface.
• Digital audio transmission and reception in Dante® for m at .
• EclerNet compat ibility.
• 4 balanced MIC/LINE inputs, phantom power and 3 levels of sensitivity, converted to
Dante® format and sent to t he net work .
• 4 balanced line outputs, converted from 4 Dante® c hannels 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 inf or m ation.
* 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 m ore information.

3. INSTALLATION
3.1. Location, set up, vent i l ati on
DN44BOB has been especially designed to be installed in a standard 19" rack, taking up 1U
(height) and only half the width.
The DN44BOB being a heat generator, it should not be enclosed or exposed to extreme
temperatures.
If multiple amplifiers are inst alled in the same rack or in a cabinet with closed doors, it is highly
recommended to install fans in their upper and lower ends f or a forced air flow from the bottom up. This
upward air flow will favour the dissipation of heat generated inside.
3.2. 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 = 30Ω 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 t op of it.
If the device requires any intervention and/or connection/ disconnection, it must be powered off
first. Ther e ar e no user-serviceable parts within the unit.
To avoid buzzing, do not allow the power cable to intertwine with audio shielded cables.
3.3. 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 term inal – t o ground.
3.4. 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 term i nal –.
6
3.5. 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 inform at ion.
• Direct connection (point-to-point) of a com put er 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.)
3.6. 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 func t ion, suc h 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 sect ion of 0,5 mm

Please consult your ECLER dealer or www.ecler.com about the W Pm ser ies remote control wall
panels.
3.7. GPO remote control ports
The DN44BOB rear panel provides 4 NO/NC (normally open/normally closed) relay outputs ( 8).
The open or closed st atus 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, light s, sirens , GPI inputs of other
equipment, etc.

3.8. Front panel LED indicators
The DN44BOB front panel provides the f ollowing elements :
• POWER LED indicator (5): lights up when the unit is on.
• DANTE LED indicator (3):
o Red LED: Ethernet network disconnected.
o Green LED: Ethernet network connected and device operating as master (transmitting
Dante® clock on the network).
o Amber 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 presenc e of an audio signal at the unit
inputs and its intensity level (green, amber and red c olours which correspond, in this order, to an
increasing level of intensity).
• Audio output (analogue) LED indicators (2): indicate t he presence of an audio signal at the unit
outputs and its intensity level (green, amber and red colours which corres pond, in this order, to
an increasing level of intensity).
4. 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.
