1. IMPORTANT NOTE
Congratulations! You're the owner of a carefully designed and manufactured product. Thank you for your
confidence and your choice of our NXA series multi-channel digital processing amplifier, with Ethernet and RS-232
remote control.
In order to obtain maximum operativity and perfect functioning order, it is most important to carefully read
all considerations taken into account in this manual before connecting this amplifier.
We recommend our authorised Technical Services if any maintenance task should be needed so that
optimum operation shall be achieved.
The NXA series is guaranteed for 3 years.
1.1. Precautions
The equipment must be correctly grounded (ground resistance, Rg = 30  or less). The environment
must be dry and dustless. Do not expose the unit to rain or water splashes, and do not place liquid
containers or incandescent objects like candles on top of the unit. Do not obstruct the ventilation grilles
with any kind of material.
If the device requires any intervention and/or connection/disconnection, it must be first powered off.
Do not handle the speaker output terminals with your device turned on, there are voltages up to 400Vpp.
The output cabling should be connected by a qualified technician. Otherwise only use pre-made flexible cables.
There are no user serviceable parts inside the amplifier.
2. INTRODUCTION
The NXA series consists of three models with 4 channels and two models with 6 channels:
o NXA4-80: 4 x 80 W RMS @ 4
o NXA4-200: 4 x 200 W RMS @ 4
o NXA4-400: 4 x 420 W RMS @ 4
o NXA6-80: 6 x 80 W RMS @ 4
o NXA6-200: 6 x 200 W RMS @ 4
All models are equipped with convection cooling, without fan, a feature allowing a very quiet operation,
suitable for installation in noise sensitive environments.
The output (amplified) channels can work independently or paired, two operating modes being then
available: BRIDGE (one pair behaves as a single higher power amplifier) or PARALLEL (one pair has two amplified
outputs, but both receive and deliver identical signals, simultaneously managed).
It also incorporates significant technological innovations regarding digital processing and remote
management via Ethernet and RS-232, making it the perfect candidate to undertake mobile applications and fixed
installations, centralized or distributed, requiring highly integrated remote control and monitoring with
standard Ethernet networks. NXA units are delivered with an internal DSP processing module and matrix
functions, as well as EclerNet remote management, that allows the physical connection of the amplifier to an
Ethernet network and its remote management and monitoring from anywhere on this one, using EclerNet Manager
(*) Windows® application. Please refer to the EclerNet Manager software manual for more information.
Other remarkable features of this series are :
 4/6 analogue audio inputs
 4/6 amplified output channels (SINGLE (independent), PARALLEL or BRIDGED modes)
 4/6 GPI remote control ports (compatible with 0-10VDC analogue devices, such as WPmVOL and
WPmVOL-SR wall panels). A GPI port can control one or more inputs or outputs (volume) or manage
the recall of presets 1 to 5 (GPI-1 only)
 Class D amplifiers (optimal energy consumption)
 Auto stand-by function (optimal energy consumption)
 100% silent, thanks to unforced convection cooling (no fan)
 First class digital audio codecs, with excellent signal-to-noise ratio
 Ethernet interface, supporting EclerNet Manager software platform and UCP (User Control Panels)
web server-web client remote control system
 RS-232 Interface
