Product Overview
The Ashly nXp1.52 is a 1500-Watt @ 4 Ohm, 2-channel network power amplifier with DSP and programmable outputs.
Ashly's line of nX Power Amplifiers feature lightweight, energy efficient Class D switching amplifier technology combined with a switch mode power supply. The nX amplifiers are available in three product families designed to meet the most demanding live sound and fixed installation sound systems in stadiums, arenas, performance venues, worship spaces and convention centers.
The Ashly nXp Series 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.
