NEXO NXAMP4x2MK2 Powered Digital TD Controller

The NEXO NXAMP4x2MK2 Powered Digital TD Controller is a compact four-channel amplification and loudspeaker-management platform developed for professional NEXO systems. Delivering up to 2,500 W per channel at 2 ohms, the NXAMP 4×2 MK2 combines Class-D amplification, 24-bit/96 kHz conversion, advanced DSP, NEXO loudspeaker presets and network control in a space-efficient 2U chassis. It is designed for professionals who need powerful amplification without moving up to the larger NXAMP 4×4 MK2.

Its combination of four amplifier channels, integrated processing and flexible connectivity makes the NXAMP4x2MK2 suitable for touring racks, rental inventories, permanent installations and appropriately configured NEXO full-range and subwoofer systems.

NXAMP4x2MK2 Power Output

Despite its relatively compact rack format, the NEXO NXAMP4x2MK2 Powered Digital TD Controller provides substantial output across common professional loudspeaker impedances.

Four independent channels give system technicians flexibility when assigning amplification to different loudspeaker sections.

This can be particularly useful in professional systems containing multiple cabinet types or independently controlled zones.

Bridge Mode for Higher-Power Applications

The NXAMP 4×2 MK2 also supports paired-channel bridge operation.

The supplied ratings are:

2 × 3,800 W at 8 Ω

and

2 × 5,000 W at 4 Ω

Bridge operation provides another configuration option where an appropriate NEXO system requires greater power from a paired amplifier channel.

System impedance and the correct loudspeaker preset must always be considered when selecting an operating configuration.

Integrated NEXO TD Controller

Amplification is only part of what the NXAMP4x2MK2 provides.

The unit also functions as a digital TD Controller designed to manage compatible NEXO loudspeakers.

Integrated processing includes:

• Parametric and graphic EQ
• Crossover management
• Delay
• Peak limiting
• Loudspeaker protection
• Routing
• Model-specific presets

This integration helps differentiate the NXAMP platform from conventional four-channel amplifiers that provide power without dedicated NEXO loudspeaker management.

24-Bit / 96 kHz Digital Processing

The NXAMP4x2MK2 uses high-resolution 24-bit / 96 kHz AD/DA conversion.

Its DSP architecture is designed to process the signal in real time while maintaining low latency.

The supplied flat-mode latency is approximately:

580 microseconds

Low processing latency is particularly important in live professional systems where several digital devices may already exist within the signal path.

Advanced 64-Bit DSP Architecture

Three 64-bit multi-core DSPs provide the processing resources required for the amplifier’s system-management functions.

Rather than relying on external processors for every function, technicians can configure important loudspeaker parameters directly within the NXAMP environment.

That helps create a more centralized workflow for compatible NEXO systems.

NEXO Loudspeaker Presets

One of the strongest reasons to choose a NEXO NXAMP4x2MK2 Powered Digital TD Controller is its integration with NEXO loudspeaker presets.

Model-specific configurations help the amplifier and connected loudspeakers operate as an integrated system.

These configurations can incorporate the appropriate processing and protection required by supported NEXO cabinets.

For rental companies maintaining multiple NEXO systems, this also makes it easier to standardize amplifier inventory.

Four Analog XLR Inputs

The unit provides:

4 × analog XLR inputs

with cascading capability.

Four inputs correspond well with the amplifier’s four-channel architecture and provide straightforward integration with professional mixing consoles and system processors.

Optional Digital Audio Connectivity

The NXAMP4x2MK2 architecture can accommodate digital/network options depending on the installed expansion hardware.

Supported options may include:

• Dante
• AES/EBU
• EtherSound
• AES67

These capabilities can be valuable in larger networked audio systems.

However, when selling an individual used amplifier, the product page should specify the actual expansion card installed rather than implying that every unit automatically includes all these formats.

Dual Ethernet Network Connections

Dual Ethernet connectivity supports professional system networking and remote management.

This allows multiple compatible devices to be connected within a larger control environment.

Network capability becomes particularly valuable when amplifier racks are located away from the system technician or front-of-house position.

Remote Control with NEXO NeMo

The NEXO NXAMP4x2MK2 Powered Digital TD Controller can form part of a remotely managed NEXO system using compatible NEXO control software.

Remote access can help technicians inspect and manage system parameters without making every adjustment directly from the physical amplifier rack.

This is useful for:

Touring productions

Large venues

Rental systems

Fixed installations

Multi-amplifier systems

4.3-Inch Color Touchscreen

Local operation is handled through a 4.3-inch color touchscreen, rotary encoder and physical controls.

This allows technicians to navigate routing, presets and other system parameters directly from the front panel.

The touchscreen-based interface also distinguishes the MK2 generation from older professional amplifier/controller designs that rely primarily on small text displays and buttons.

Professional Loudspeaker Protection

High-output professional amplifiers need more than basic electrical protection.

The NXAMP4x2MK2 combines amplifier protection with loudspeaker-management functions.

Protection systems cover conditions such as:

• Short circuits
• Overload
• Excessive temperature
• DC conditions
• Loudspeaker operating limits

Combined with the correct NEXO presets, these functions help manage compatible loudspeakers within their intended operating parameters.

Universal 100–240 V Power Supply

The amplifier uses a universal power architecture covering:

100–240 VAC

with Power Factor Correction.

This makes the platform suitable for professional systems operating across different markets, provided that local electrical infrastructure and connection requirements are observed.

Standby consumption is approximately 10 W, while the supplied idle figure is around 200 W.

Compact 2U Rack Format

One major difference between the NXAMP 4×2 MK2 and its larger sibling is physical size.

The NXAMP4x2MK2 occupies:

2U of rack space

with an approximate weight of:

16.1 kg

This combination can be particularly attractive to touring and rental companies trying to increase amplifier channel density without unnecessarily increasing rack size and transport weight.

Technical Overview

NXAMP4x2MK2 vs NXAMP4x4 MK2

For buyers comparing the two MK2 platforms, the most obvious difference is available amplifier output.

The NXAMP4x2MK2 therefore makes sense when a system does not require the substantially greater output of the 4×4 MK2 and a more compact amplifier rack is desirable.

The 4×4 MK2 is the higher-output option for more demanding configurations.

NXAMP4x2MK2 for Touring Systems

Touring companies need equipment that combines performance with efficient logistics.

A 2U four-channel amplifier/controller helps reduce rack space while providing amplification and processing within the same platform.

That can simplify system preparation and reduce the number of separate devices that need to be transported and connected.

A Practical Choice for Rental Companies

Professional rental businesses running NEXO loudspeakers can use the NEXO NXAMP4x2MK2 Powered Digital TD Controller as part of standardized amplifier inventories.

Multiple units can support different system packages while allowing technicians to remain within a familiar NEXO control environment.

This can be useful for rental businesses managing several events simultaneously.

Fixed Installation Applications

The NXAMP4x2MK2 is equally relevant to permanent professional installations.

Potential environments include:

• Theatres
• Clubs
• Live venues
• Houses of worship
• Performance spaces
• Corporate facilities
• Entertainment venues
• Multi-zone professional systems

Its network control options can be particularly useful when amplifiers are installed in equipment rooms away from the primary control position.

Why Choose the NEXO NXAMP 4×2 MK2?

The NXAMP4x2MK2 offers an attractive balance between output, processing and physical size.

Four amplifier channels provide up to 2,500 W each at 2 Ω, while integrated NEXO processing handles loudspeaker management and protection.

At the same time, the 2U chassis and approximately 16.1 kg weight make it more compact than the higher-powered NXAMP4x4 MK2.

For appropriately sized NEXO systems, that balance can be more valuable than simply choosing the highest-powered amplifier available.
