Product Description

NSXP-4120 is a high-performance, four-channel Class D car amplifier. With a wide frequency response range of 20Hz to 20kHz, the NSXP-4120 faithfully reproduces audio details from deep lows to crisp highs, making it ideal for building balanced multi-channel audio systems. Its input sensitivity range of 200mV to 6V allows for compatibility with a wide range of audio sources, from original head units to high-end players, ensuring stable transmission and excellent sound quality. The amplifier also features an adjustable crossover frequency (LPF/HPF) with a range of 30Hz to 350Hz, allowing users to flexibly set low-pass or high-pass filters based on speaker type, achieving professional sound control. A three-position X-over selector (LPF/FULL/HPF) further enhances system flexibility, enabling the amplifier to power either the tweeter or woofer independently, or function as a full-range amplifier.
