3. INSTALLATION

3.1. Location, assembly, ventilation

NXA series products have a 19" rack format (2RU).
It is very important not to enclose the amplifier or expose it to extreme temperatures as it generates heat.
It's also necessary to promote the passage of fresh air through the ventilation holes of the chassis, leaving
at least one rack unit off (two in case of NXA4-700) between each device and installed above and below it
in the rack frame.
If multiple products 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 airflow from the bottom up.. This upward air
flow will help to dissipate the heat generated inside.
In order to optimize as much as possible the correct thermal dissipation of equipment installed in a closed
rack, it is advisable not to place power amplifiers under other appliances, but upon these ones.
All NXA series products are supplied with plastic washers in order to be mounted in a rack without
damaging the mounting ears.

3.2. Mains connection

NXA series products are powered by 110-120, 220-240VAC, 47 / 63Hz , depending on the country (see
nameplate on the device).
The mains cables must not be near the shielded cables carrying the audio signal, as this could cause
humming.

3.3. Signal input connections

NXA series rear panel provides analog, balanced, line level signal inputs. The selection of hardware inputs
and their routing and mixing towards either amplifier channel is performed from the EclerNet Manager control
application. Please refer to the EclerNet Manager software manual for more information.
Signal input connectors are 3 position screw terminal block (7). The wiring is:
HOT or direct signal
COLD or inverted signal
GROUND
For unbalanced connection short-circuit pin 
to pin -.
STACK outputs (8) available for inputs 1 and
2 are parallel to the input and serve to re-send the
signal of these inputs (INPUTS, CH1 / CH2) to other
input channels, amplifiers or sound systems.
The input impedance is 22K (balanced). This impedance makes possible to parallel several amplifiers
without loosing audio quality.
