NXAMP4x4 MK2 Features and Specifications
What Is the NXAMP4x4 MK2?
The NXAMP4x4 MK2 is a powered TD controller developed by NEXO for professional loudspeaker systems. The “powered” design means that the device incorporates amplification rather than functioning only as a standalone digital loudspeaker processor.
The controller is designed around four amplifier channels and digital signal processing. This allows compatible NEXO loudspeaker systems to be powered and processed from a single rack-mounted unit.
The NXAMP4x4 MK2 is intended for professional applications where sound system performance, system protection, configuration flexibility and efficient equipment deployment are important.
A powered controller can be especially useful in professional sound reinforcement because the amplifier and processing functions are designed to work together. Instead of treating the amplifier and loudspeaker processor as completely independent devices, the system can use coordinated processing designed around compatible NEXO loudspeaker configurations.
For production companies, this can make system deployment more predictable. Engineers can configure the appropriate loudspeaker system, amplification and processing as part of a coordinated workflow.
NXAMP4x4 MK2 Professional Amplification
The amplification section is one of the most important characteristics of the NXAMP4x4 MK2.
NEXO specifies four amplifier channels, with the channels capable of being bridged in pairs. This provides flexibility when configuring compatible loudspeaker systems and when a production requires different power arrangements.
In four-channel operation, NEXO lists maximum output power of 4 × 1900 W with an 8-ohm load per channel. At 4 ohms, the published maximum is 4 × 3300 W, while at 2 ohms the published maximum is 4 × 4500 W.
When operating in two-channel mode with paired channels bridged, the published maximum output is 2 × 6600 W at 8 ohms and 2 × 9000 W at 4 ohms.
These values should not be interpreted as a recommendation to operate every loudspeaker system at every available load. The appropriate configuration depends on the connected NEXO loudspeaker system, system presets, deployment requirements and manufacturer recommendations.
Professional audio systems should always be configured according to the loudspeaker manufacturer’s documentation.
Four Amplifier Channels
The four-channel architecture gives the NXAMP4x4 MK2 flexibility for multi-way loudspeaker systems and professional sound reinforcement configurations.
Four amplifier channels can be used to distribute power across different parts of a compatible loudspeaker system. Depending on the system design, the available channels can support different combinations of loudspeakers, low-frequency systems and other compatible components.
The advantage of having multiple amplifier channels in one rack unit is that the system can be organized around a centralized amplification point.
For touring companies, fewer separate amplifier units can also make equipment organization easier. Rack design, cabling and system setup can be planned around the powered controller.
Bridgeable Amplifier Channels
The NXAMP4x4 MK2 amplifier channels can be bridged by pairs.
Bridging can provide a higher-power configuration for compatible loads. However, bridging should only be used when the loudspeaker system and configuration are designed to support it.
Professional users should always verify the correct configuration before connecting loudspeakers.
This is particularly important for high-power audio systems because incorrect amplifier configuration can damage loudspeakers or create unsafe operating conditions.
NXAMP4x4 MK2 Digital Signal Processing
