The NXAMP4x4
processing, inherited from the first generation
NXAMP, coupled with a state-of-the-art four
channel Class-D amplifiers, two robust universal
power supply with separate PFC and a
comprehensive user interface.

MK2 combines advanced signal

Road proof Power Supply

With its continuous usuable mains voltage range
from 100 to 240 Volts, the NXAMP4x4MK2 can be
used worldwide and run on all kinds of power
generator. Its power supplies use a PFC (Power
Factor Correction) technology, ensuring that the
efficiency of the power conversion is always at is
best, while the current drawn is smoothed and
spike-free to limit the stress on the mains network.

Flexible audio input system

Natively the NXAMP4x4MK2 has four high-end
analog inputs using cascaded converters. This
technique allows a very low output noise even with
powerful amplifiers. Four digital inputs are also
available through the expansion slot, offering
AES/EBU, Ethersoundtm, Dantetm or AES67 input
capacity, all with an automatic analog fallback
possibility.

Extended computing capacities

With its multicore ARM CPU and not less than
three multicore DSPs, the NXAMP4x4MK2 is ready
for years of new algorithms and compatibility with
the latest generation software.

Unique Class-D amplifier design

While the concept of Class-D amplifiers is well
know for decades, the major profesional power
amplifiers manufacturers are jealously keeping their

know-how in the way the power amplifier stage is
driven, by more and more complex and intelligent
circuits.

In this domain the NXAMP4x4
LSI (Large Scale Integrated) chip specifically
designed and manufactured by Yamaha, that
cannot be found in any other amplifier in the
NXAMP category.

The result is an unbelievable precise and clear
sound with an extremmely low distortion even at
high level.

MK2 uses a dedicated

User Interface

The user interface has been massively improved
regarding the first generation NXAMP. All
information is now clearly displayed on a large 4.3
inches color and tactile display, while the NeMo
inspired interface design makes all parameters
easy to monitor or to set-up.

Communication ports

By default the expansion slot, compatible with the
already existing extension cards, is fitted with a
remote control card, offering 2 x RJ45 ports for
remote control, firmware update and easy daisy
chain between NXAMPMK2 devices.

The classical Serial port and GPIO port from the
first generation NXAMP are also available, to
communicate with the DMU (Digital Metering Unit)
and the DPU (Digital Patching Unit).

Road Ready racks

As an option, Nexo offers a 6U touring rack, with
front and back integrated sliding doors, that can be
fitted with 2x NXAMP4x4MK2, or 1x NXAMP4x4MK2
plus a DPU and a DMU.

Power consumption (Idle) 270 Watts
