The nXp1.54 amplifier designed to meet the most demanding live sound and fixed installation sound systems in stadiums, arenas, performance venues, worship spaces and convention centers.
Sound systems in large architectural spaces require flexibility and big power whether it’s for line arrays, distributed sound systems, Left/Center/Right 3 and 4-way speaker systems, our new nX Series delivers up to 12,000W of clean power in a convenient 2U package. What’s more impressive is the nX Energy Management System with defeatable <1W sleep-mode (<1W energy consumption beats the most aggressive Energy Star benchmark†). nX Amplifiers have multiple independent power supplies that provide increased performance and reliability.
nXp Series amplifier 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. The nXp Series has all the features plus comprehensive signal processing using Protea™ DSP, as well as swept load impedance monitoring for system maintenance.- Features
