Only 1 left

Price includes 7% GST



The nXp1.52 Network Power Amplifier from Ashly Audio is the networkable version of the nX amplifier. It comes with Ethernet control, serial data control, aux preamp outputs, instant standby mode, preset recall, fault condition logic outputs, and optional network audio and digital audio capability. All these are controlled using Ashly Audio's Protea software suite. This amplifier is designed to meet the most demanding live sound and fixed installation sound systems in stadiums, arenas, performance venues, worship spaces, and convention centers.


The Network Power Amplifier adds 32-bit SHARC DSP processing (with 48 kHz and 96 kHz sampling) as standard equipment for comprehensive audio processing, with built-in signal generator for test tone, and noise-masking. Plus, you get precision load impedance monitoring on each amplifier channel output.
