Product Overview

nX Amplifiers with Programmable Outputs

Steady. Efficient. Powerful. nX.

Ashly’s new line of nX Power Amplifiers feature lightweight, energy-efficient Class-D switching amplifier technology combined with a switch mode power supply.

Available in three product families, nX is designed to meet the most demanding live sound and fixed installation sound systems in stadiums, arenas, performance venues, worship spaces and convention centres.

nXp Series: These amplifiers add 32-bit SHARC DSP processing (with 48kHz & 96kHz sampling) as standard equipment for comprehensive audio processing, with built-in signal generator for test tone, and noise-masking. Plus precision load impedance monitoring on each amplifier channel output. All controlled using our proprietary Protea™ Software Suite.

When you choose Ashly nX, you choose a hand-built, US-made product backed by our team of engineers and an industry-leading 5-year warranty.
