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.

nX Series: The base model amplifier, available in either 2 or 4-channel models. Use rear panel DIP switches to program each channel output for either High-Z (70V or 100V Constant Voltage) or Low-Z (stable down to 2 Ohms) operation. When in Sleep Mode, the nX amplifiers draw less than 1 Watt.

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.
