Nexo NXAMP4x4 MK2 Powered Digital TD Controller/Amplifier for Sale
The Nexo NXAMP4x4 MK2 Powered Digital TD Controller/Amplifier for sale combines four high-output Class-D amplifier channels with integrated DSP, loudspeaker management and NEXO system control in a single professional platform. Designed for demanding touring and fixed-installation systems, the NXAMP4x4 MK2 delivers up to 4,500 W per channel at 2 Ω, incorporates 24-bit/96 kHz conversion, and provides loudspeaker-specific processing for compatible NEXO systems. It is a practical choice for rental companies, venues and system integrators that want amplification and dedicated loudspeaker management in one unit.
Unlike a conventional four-channel power amplifier, the NXAMP4x4 MK2 is designed as part of the wider NEXO ecosystem, bringing amplification, processing, protection and system configuration together.
Nexo NXAMP4x4 MK2 Power Output
The Nexo NXAMP4x4 MK2 Powered Digital TD Controller/Amplifier uses four independent Class-D amplifier channels engineered for professional high-output applications.
Output per Channel
| Load | Output Power |
|---|---|
| 8 Ω | 1,900 W |
| 4 Ω | 3,300 W |
| 2 Ω | 4,500 W |
With all four channels available independently, the amplifier provides the flexibility needed for multi-way systems and larger professional NEXO configurations.
Its maximum unloaded channel voltage is approximately 180 V peak.
High-Power Bridge Mode
Where an appropriate system configuration requires additional output, amplifier channels can be paired for bridge operation.
The supplied bridge-mode figures are:
- 6,600 W into 8 Ω
- 9,000 W into 4 Ω
This gives system designers additional flexibility when configuring suitable high-power professional loudspeaker loads.
Any bridge configuration should follow the correct NEXO system requirements and load limitations.
Integrated Digital TD Controller
One of the main reasons to choose a Nexo NXAMP4x4 MK2 Powered Digital TD Controller/Amplifier for sale rather than a generic amplifier is its integrated loudspeaker-management architecture.
The NXAMP platform combines power amplification with digital processing designed around NEXO loudspeaker systems.
This provides control over functions such as:
Equalization
Crossover processing
Delay
Limiting
Preset selection
Loudspeaker protection
Instead of building a system from separate amplifiers and external processors, compatible NEXO systems can be managed from one integrated platform.
24-Bit / 96 kHz Digital Processing
Signal conversion operates at 24-bit / 96 kHz, supported by high-performance DSP architecture.
This gives the processor the resolution required for detailed professional system management while maintaining very low processing latency.
The supplied specification indicates latency of approximately:
580 μs in a flat configuration
Low latency is particularly important in professional live-sound applications where unnecessary processing delay needs to be minimized.
NEXO Loudspeaker Presets
An important benefit of the NXAMP architecture is access to dedicated configurations for compatible NEXO loudspeakers.
Rather than relying solely on manually created generic crossover settings, system technicians can work with NEXO-specific configurations intended for the loudspeaker platform being deployed.
This can simplify setup while supporting correct:
- Frequency management
- Driver protection
- System limiting
- Crossover behavior
- Amplifier configuration
The correct preset should always be selected for the exact loudspeaker model and system configuration.
4.3-Inch Touchscreen Interface
The front panel provides a 4.3-inch color touchscreen combined with a rotary encoder.
This gives technicians direct access to system settings without requiring a computer for every adjustment.
The interface can be used to navigate configuration parameters and inspect important system information directly from the amplifier rack.
For rental companies, this can make onsite setup considerably more convenient.
Four Analog XLR Inputs
The amplifier provides:
4 balanced analog inputs
These allow four independent source channels to be routed into the system.
The input architecture supports professional balanced audio connections and can be integrated into larger touring, venue or installed-sound signal chains.
Four NL4 Loudspeaker Outputs
Four Speakon NL4 outputs provide loudspeaker connections.
This gives the NXAMP4x4 MK2 a straightforward physical output architecture for professional speaker systems.
However, cabling and pin configuration should always match the specific NEXO loudspeaker and system arrangement being used.
Expandable Digital and Network Connectivity
The Nexo NXAMP4x4 MK2 Powered Digital TD Controller/Amplifier can support additional connectivity through compatible expansion options.
Depending on the installed card and system configuration, this may include technologies such as:
- Dante
- AES/EBU
- EtherSound
This makes the amplifier relevant to professional environments moving beyond traditional analog-only signal distribution.
Because expansion cards are optional, a specific used NXAMP should not be advertised as including Dante, AES/EBU or EtherSound unless the installed card has been physically confirmed.
RS-232 and GPIO Integration
Additional control and integration options include RS-232 and GPIO connectivity.
These interfaces can be useful in permanent professional installations where the amplifier needs to interact with broader control or monitoring infrastructure.
That extends the product’s relevance beyond concert touring into theatres, entertainment venues and other engineered installations.
Built-In Protection for Professional Systems
High-power amplification requires comprehensive protection.
The NXAMP4x4 MK2 incorporates system-management functions intended to protect both the amplifier and compatible loudspeaker system.
Protection covers operating conditions such as:
- Thermal stress
- Overload
- Short circuit
- Output clipping
- Loudspeaker operating limits
This integrated approach is particularly important when an amplifier can deliver several thousand watts per channel.
Universal Power Supply with PFC
The power section incorporates Power Factor Correction (PFC) and supports a broad mains input range.
The supplied range is:
100–240 V AC
This makes the platform suitable for professional applications across different markets, subject to the appropriate mains infrastructure, connectors and electrical requirements.
Supplied consumption figures are approximately 10 W in standby and around 200 W at idle.

NXAMP4x4 MK2 for NEXO Professional Systems
The Nexo NXAMP4x4 MK2 Powered Digital TD Controller/Amplifier for sale is particularly relevant to businesses already using NEXO loudspeakers.
Instead of adding an unrelated amplifier platform, existing NEXO owners can maintain a more integrated system architecture.
Potential applications include compatible:
Line arrays
Point-source systems
Subwoofer packages
Touring systems
Rental inventories
Permanent installations
This makes NXAMP searches highly transactional because many potential buyers already know the exact amplifier/controller their system requires.
Professional Touring Applications
Touring sound companies require equipment that can handle demanding professional workloads while remaining flexible enough for different system configurations.
The four-channel architecture allows technicians to configure multiple loudspeaker circuits within one amplifier.
Integrated DSP also reduces dependence on separate external processing hardware for supported system functions.
That can help simplify touring racks and system deployment.

Typical applications can include:
Theatres
Live music venues
Clubs
Performance halls
Houses of worship
Entertainment facilities
Large event spaces
Network and control expansion options can further support integration into sophisticated installed systems.
