Positioned in power rating between NEXO’s nanoNXAMP4 and NXAMPMk2 Powered TD Controllers, the microNXAMP4X1 combines advanced signal processing for all NEXO speakers with 4-channel Class-D amplifiers, a universal power supply with PFC and native Dante connectivity. Available in both touring and fixed installation versions with appropriate connectivity for each, the microNXAMP4X1 can be used with the P+ Series, with the aim of making systems configured from NEXO’s point source speaker range more cost-effective in a wide variety of applications.

Housed in a 1U rack-mounting case, the microNXAMP4X1 features a 1.8-inch colour TFT on the front panel displaying essential information including level meters and IP address, with all DSP parameters easy to monitor or set up using NEXO’s NeMo remote control software. The four Class-D amplifier channels deliver 1,000W each into 4Ω and can be bridged in series and also in parallel to support lower output impedance, or both combining the four channels into a 4,000W output. These various modes are configurable from the software and do not need external adaptors.

The microNXAMP4X1 features two multicore DSPs inherited directly from NEXO’s flagship NXAMPMk2, providing a futureproofed hardware platform, equipped to host new algorithms and run next-generation firmware updates for years to come. With its continuous usable mains voltage range from 100–240V, the microNXAMP4X1 can be used worldwide and run on all kinds of power generators. PFC (Power Factor Correction) technology ensures power conversion efficiency is always optimised and that the current drawn is smoothed and spike-free to limit stress on the mains network. The microNXAMP4X1 power consumption in stand-by mode conforms with Energy Star certification requirements. A variety of wake-up modes include a network command, audio level detection or front-panel button press, ensuring that stand-by power consumption is tailored to the specific requirements of each use case.
