New York, NY (November 10, 2026)—Landing in the middle of Nexo’s nanoNXAMP4 and NXAMPMk2 Powered TD Controllers is the company’s new microNXAMP4X1. The 1RU unit provides signal processing for all Nexo speakers, offering four channel Class-D amplifiers, Dante connectivity and a universal power supply with Power Factor Correction.
The new microNXAMP4X1 is available in both touring and fixed installation versions with appropriate connectivity for each. Largely intended for the company’s P+ Series point source speaker range, the microNXAMP4X1 is housed in a compact 1U rack-mounting case and features a 1.8-inch color TFT. Placed on the front panel, the TFT provides a variety of information, including level meters, IP address and so on; all DSP parameters can be monitored or set-up using Nexo’s NeMo remote control software.

The microNXAMP4X1’s four Class-D amplifier channels deliver 1000W each into 4 Ohms and can be bridged in series—the classic ‘bridge’ mode for power amplifiers—and also in parallel to support lower output impedance, or both, combining the four channels into a 4000W output. The 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, equipped to host new algorithms and run next-generation firmware in the years ahead.

With its continuous usable mains voltage range from 100 to 240 Volts, the microNXAMP4X1 can be used worldwide; its PFC (Power Factor Correction) technology ensures power conversion efficiency is optimized and that the current drawn is smoothed and spike-free.
