Mono Block Class D Amplifier

NSMR-1.500D monoblock class D amplifier measures 240mm (length) x 176mm (width) x 46mm (height). Its compact design and flexible installation make it suitable for a wide range of vehicle types, especially for retrofits where space is limited. It utilizes highly efficient Class D amplification technology to ensure higher energy efficiency, lower heat generation, and a balance of stability and performance. A low-pass filter (LPF) precisely controls the output frequency band, ensuring more focused and detailed bass. A subsonic filter (15Hz to 50Hz) effectively filters out unwanted ultra-low-frequency noise, protecting the speakers and enhancing sound purity. To further enhance low-frequency performance, the amplifier features a built-in adjustable bass boost (Bass Boost 0–6dB), allowing users to adjust the bass level to suit their musical style or personal preference.

NSMR-1.1000D is a high-performance mono Class D car amplifier designed for audiophiles seeking powerful bass and system stability. It delivers powerful output under varying loads: 450W RMS at 4 ohms, 680W RMS at 2 ohms, and up to 1000W RMS at 1 ohm. This powerful output easily drives a wide range of high-power subwoofers, injecting powerful low-frequency energy into your car's system. It offers enhanced energy efficiency and lower heat generation, ensuring stability even during extended playback. A 15Hz to 50Hz subsonic filter effectively eliminates unwanted low frequencies, protecting the speakers while enhancing sound clarity. A variable bass boost function (0–6dB) allows users to customize the bass impact and enhance the listening experience.

NSMR-4075 4-channel Class A/B amplifier delivers up to 75W RMS into a 2-ohm load and a powerful 130W RMS output in bridge mode, meeting the demands of diverse audio systems, whether driving multiple speakers or achieving even stronger bridged output. Utilizing classic Class A/B amplification technology, the NSMR-4075 boasts exceptional linear response and low distortion, ensuring pure, detailed sound quality and significantly enhancing the layering and dynamics of music. The amplifier features flexible crossover selection, supporting LPF (low-pass filter), HPF (high-pass filter), and full-range modes, allowing users to freely adjust the sound balance based on speaker characteristics and system layout. The low-pass filter frequency range is adjustable from 30Hz to 250Hz, while the high-pass filter frequency range is 50Hz to 500Hz, accommodating diverse crossover requirements.
