NXAMPMK2 | 4 Channel Powered TDControllers
Formidable power. Precision control.
Flexible networking.
The perfect compact, light-weight power solution for NEXO systems
NEXO and Yamaha collaborate to set new
performance standards in power amplification
NEXO’s expertise in DSP control for high-performance loudspeakers
is unparalleled in the sound reinforcement industry. And Yamaha
has an unrivalled heritage in developing highly efficient and reliable
power amplification devices. So when the two collaborate to
create a new range of powered controllers, the result is sure to be
something special.
Available in 4 X 1300 Watts and 4 X 2500 Watts
versions, the NXAMPMK2 combines advanced signal
processing with four state-of-the-art Class D amplifiers
to create a flexible, light-weight powering and control
solution for NEXO loudspeaker systems.
Ideal for use in fixed installations and touring, these powered
controllers are easy to set up and quick to deploy, with all
essential parameters readily accessible via a large colour touchscreen on the front panel and a comprehensive range of control
and networking facilities on the rear panel.
Most importantly, the new NXAMPMK2 achieves a whole new level
of sound quality, partnering with NEXO speakers to deliver a
whole new level of audience experience.
Joseph Carcopino
R&D Director, NEXO
A new version is always a challenge, especially when the original
has been successful! But our Yamaha/NEXO mixed team of
passionate engineers accepted this challenge, merging their knowhow, culture, sensitivity, and finally delivering this NXAMPMK2 that,
when coupled with our acclaimed NeMo software, offers one of the
top powering and processing solution worldwide.
Ken Iwayama
Group Manager, PA Development Department, Yamaha
Our engineering team worked with NEXO R&D, implementing
many new ideas to make this new generation of NXAMP deliver
a significant improvement and upgrade on sound quality, power
capability, efficiency, compactness, functionality, and reliability.
We believe that the NXAMPMK2 superbly supports the NEXO sound,
consistent with our passion for music.

4 X 1300 / 2500 Watts from a 2U rack
The Nexo NXAMPMK2 ultra-low distortion Class D amplifiers
combine 32-bit/96KHz converters and 64-bit signal
processing to deliver significant advances in sound quality
over the already highly regarded previous generation of
NXAMPs. Bass is solid and high-end definition is particularly
impressive in a sonic performance that is both articulate and
rich with detail. Even at low volumes, the sound is noticeably
transparent and pure. The amplifiers integrate three new multi
4
core DSPs providing a future-proofed hardware platform,
equipped to host new algorithms and run next-generation
firmware updates for years to come.
With a mains voltage range of 100 to 240 Volts it means
the amplifiers can be used anywhere in the world and run
on all types of power generators. Robust power supplies
use PFC (Power Factor Correction) technology to ensure
maximum power conversion efficiency and that the current
drawn is smoothed and free of spikes to limit the stress
on the mains network at all times. A flexible audio input
system encompasses four, high end analogue inputs using
cascaded converters for low output noise. Four digital inputs
are also available through the rear panel expansion card slot
offering optional AES/EBU, EtherSound™, Dante™ or AES67
inputs, all with automatic analogue fall-back. A native dual
Ethernet card facilitates remote control and daisy-chaining
of amplifiers, and seamless integration with Nexo’s NeMo
amplifier management software. In addition to the expansion
card slot, other rear panel connectivity includes RS232
serial and GPIO ports along with Speakon outputs for each
of the four channels. Occupying only 2U of rack space, the
NXAMP4X1MK2 and NXAMP4X2MK2 weigh in at just 15.7kg and
16.1kg respectively.

In addition to cabinet-related EQ and Array EQ,
User EQ provides up to 8 bands per channel,
editable on one or several channels at once.
User EQ is drawn in full screen for a better
experience. The band type, frequency, gain,
Q and on/off status can be easily edited.
The inputs view displays input levels and
offers input alignment options. The input patch
can be intuitively edited.
Load Monitoring can be enabled and configured
on every channel, to ensure speakers are
monitored in real time and ready to use.
Many parameters and alerts are always
recorded into the log, providing valuable
information on the NXAMPMK2 usage.
NEXO or Custom Setup can be edited on one
or several channels. The cabinet name, its
cross-over and output patch are always visible.
The System Headroom page gives real time
information on amplifier levels and speaker
temperature, displacement and protection levels.

Network cards
NXDT104MK2
The optional Dante card enables seamless integration of NXAMPMK2 into Dante audio
networks. It receives 4 audio streams (24-bits / 48kHz) in the Dante or AES67 formats
and allows remote control from any computer on a LAN using TCP/IP commands.
Its unique 3-port design can be used as an integrated 3 port gigabit switch or as two
Dante redundant ports plus an optional third port for additional remote control.
Total system management control
For MacOS and iOS devices
A large number of NXAMPMK2 amplifiers can be conveniently
controlled via a wired or WiFi network from a Mac or iOS device
using NEXO’s system management software NeMo. Following the
automatic ‘discovery’ of available amplifiers, sessions can be easily
prepared by arranging devices on a map over a background image,
and groups of devices and zones of channels can be created.
Sessions can be prepared both online and offline.
channels, enabling different layers of EQ, and parameters can be
copied and pasted, and changes undone and redone, even online.
A Quick Mute / Solo page makes it easy to check the system by
soloing every channel and is perfect for checking settings and
monitoring levels. Finally, a powerful Logging and Alerting system
covers levels, protections, temperatures, currents, voltages and
errors.
NeMo enables editing of parameters of several devices or channels
simultaneously, using groups and zones. A library of presets makes
set-up quick and easy, and settings like Volume and Delay can be
changed absolutely or relatively. EQ can also be edited on several
NeMo can be used via the optional network cards, or via the
included Remote Control card.
Firmware Updates
Firmware updates can be downloaded from the NEXO website and installed
via the RJ45 port on the Remote Control card. Firmware update software
can run on both Windows and Mac and can download both first generation
and MK2 NXAMP firmware simultaneously, its multithread architecture
allowing downloading to multiple amplifiers to save time. There’s a
dedicated Firmware Update screen in the user interface which also displays
the current Firmware version.

NXES104
The optional EtherSound card extracts 4 audio streams (24-bits / 48kHz) from the
2 X 64 channels of an ES100 EtherSound stream and features In and Out ports for
easy daisy-chaining without an external switch and a third port for remote control
and ASIO streaming.
AES/EBU NXAE104
The optional AES/EBU card receives 4 audio channels (24-bits / 44.1 - 96kHz) in
AES/EBU format and features 2 X AES/EBU stereo XLR inputs; one with an AES/
EBU buffered output on XLR with fail-safe relay. 2 X switched RJ45 ports enable
remote control and easy daisy chaining.
Remote Control NXRM104
Supplied as standard with the NXAMPMK2, the Remote Control card features
