NXAMP4x2MK2 Features and Specifications

What Is the NXAMP4x2MK2?

The NXAMP4x2MK2 is a powered TD controller from NEXO designed for professional sound reinforcement systems.

The controller combines power amplification and digital loudspeaker processing in one unit.

This integrated approach is useful because professional loudspeakers often require more than simple amplification. They require appropriate filtering, system processing, protection and configuration.

The NXAMP4x2MK2 is designed to provide these functions as part of a NEXO-based sound system.

NXAMP4x2MK2 Amplifier

The NXAMP4x2MK2 contains four amplifier channels.

NEXO specifies the amplifier as a Class-D design intended for professional sound reinforcement.

The four channels provide flexibility for multi-way loudspeaker systems and other compatible configurations.

The channels can also be bridged in pairs when the connected loudspeaker configuration requires a higher-power amplifier arrangement.

NXAMP4x2MK2 Output Power

The NXAMP4x2MK2 provides different maximum output levels depending on the load and operating mode.

In four-channel operation, NEXO specifies:

• 4 × 1200 W at 8 ohms
• 4 × 1900 W at 4 ohms
• 4 × 2500 W at 2 ohms

In two-channel bridged operation, NEXO specifies:

• 2 × 3800 W at 8 ohms
• 2 × 5000 W at 4 ohms

The maximum output figures should always be considered together with the requirements of the connected loudspeaker system.

The highest available amplifier output is not automatically the correct configuration for every loudspeaker.

Users should follow the appropriate NEXO system documentation and presets.

Four-Channel Amplification

Four amplifier channels allow the NXAMP4x2MK2 to support professional multi-channel sound reinforcement configurations.

Each channel can be assigned according to the requirements of the compatible loudspeaker system.

This makes the controller suitable for systems where different loudspeaker components require separate amplifier channels.

Four-channel operation can also help reduce the number of separate amplifier units required in a professional rack.

Bridged Amplifier Operation

The four amplifier channels can be bridged in pairs.

Bridging combines amplifier channels to provide a higher-power configuration for compatible loads.

This feature provides additional flexibility for professional system designers.

However, bridged operation should only be used when the connected loudspeaker system supports it.

Always confirm the required configuration before connecting a loudspeaker.

NXAMP4x2MK2 Digital Signal Processing

Digital signal processing is a major part of the NXAMP4x2MK2 architecture.

NEXO specifies three multicore 64-bit processing DSPs.

The final acoustic performance of a sound system depends on the complete system, including loudspeakers, acoustic environment, deployment and system tuning.

NXAMP4x2MK2 Frequency Response

The current NEXO specification lists a frequency response of ±1 dB from 10 Hz to 20 kHz.

A controlled frequency response is important in professional audio because it allows the electronic system to reproduce the incoming signal consistently.

However, the acoustic response heard by the audience is influenced by the loudspeaker and the room.

The NXAMP4x2MK2 therefore works as one component in a complete sound reinforcement system.

NXAMP4x2MK2 Dynamic Range

NEXO lists a dynamic range of 110 dB unweighted.

Dynamic range describes the difference between the lower usable signal level and the highest signal level within the specified operating conditions.

A wide dynamic range is useful in professional sound reinforcement because music and speech contain both quiet details and high-level peaks.

NXAMP4x2MK2 Latency

The current NEXO product specification lists approximately 580 microseconds of latency on a flat setup.
