9. EclerNet COMPATIBLE DEVICES, Part IV: NXA series, self-powered digital
audio manager
9.1. Introduction to NXA series
NXA is a series of "all-in-one" digital audio devices: a multichannel self-powered digital manager, an
evolution of the EclerNet NZA series of amplifiers integrating a digital audio matrix. In some projects, a
digital amplifier with Ethernet/RS-232 remote control is essential, yet insufficient to meet all
requirements, as input signal mixing, source selection, priorities, self-diagnostics for the correct
operation of the device, user control interface, etc.. Adding a digital matrix to the equipment list may
exceed the budget. This is where the NXA series fits perfectly: an amplifier/processor hybrid digital
device, a complete audio solution that provides multiple methods of remote control with a long list of
features.
NXA device programming is performed with the EclerNet Manager application, either via a CAT5 point-
to-point connection (directly from the computer to the NXA device) or from a remote point of the Ethernet
network it is linked to.
The remote management for NXA and in general for any EclerNet compatible device (as NZA or NPA
amplifiers, or MIMO88 matrix) can be done in the following ways:
 with the EclerNet Manager application, either via a CAT5 point-to-point connection (directly from
the computer to the NXA) or from a point of the Ethernet network it is linked to
 from EclerNet clients of Ethernet Manager, or UCPs (User Control Panels): several simultaneous
web clients, each with its own custom control panel, and EclerNet Manager acting as a web
server. EclerNet Manager allows to create such control panels in a very simple and intuitive
manner
 from external “third-party” control devices (Crestron®, AMX®, Extron®, VITY®, Medialon®, RTI®,
etc.), using for this the TP-NET Ecler communication protocol integrated in the NXA series and
the Ethernet or RS-232 communication of the device
The NXA has 4 or 6 analogue audio inputs and 4 or 6 amplified outputs (4 or 6 channels, depending on
model), from 80W per channel up to 400W per channel (depending on model). All inputs are balanced,
at a nominal line level, while the amplified outputs can be set to work in SINGLE, PARALLEL or BRIDGE
mode.
With EclerNet Manager you can configure the NXA for all types of audio processing tasks (DSP or Digital
Signal Processing) on incoming signals, such as:
 Independent audio input mixer for each channel of the device (mixing matrix), allowing to
generate a different mixing than the ones made in the other channels
 Independent controls per channel: VOLUME, MUTE, SOLO, PHASE INVERSION, MAX. VOL
(upper volume limit) and MIN. VOL (lower volume limit)
 LP and HP crossover filters, up to 4th order, per channel
 Bank of 8 parametric EQ filters, per channel
 Compressor with THRESHOLD, COMP. RATIO, ATTACK, RELEASE, and MAKE-UP KNEE
GAIN settings, per channel
 Delay, up to 1000 milliseconds, per channel
 DUCKER function (priority): an input can be configured with highest priority, being able to reduce
and replace the audio content of any channel, when its signal exceeds the detection threshold.
This feature is vital in emergency/evacuation systems, which should play a specific alarm and/or
evacuation message instead of the regular audio program when an emergency scenario is
detected
 5 configuration memories (presets) are available
As inputs for hardware control devices, the NXA has 4 or 6 GPI ports (depending on model), or General
Purpose Inputs, 0-10 VDC. These control inputs can be connected to external devices such as contact
closures, potentiometers, Ecler WPm series panels, 0-10 VDC voltage sources, etc..
