3. INSTALLATION

3.1. 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.
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.

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 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.

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
Cold or inverted signal
Ground
For UNBALANCED connection, short circuit the terminal – to 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
Cold or inverted signal
Ground
For unbalanced connection, don't connect the terminal –.
