2 Channel Mini Size Class D Amplifier

NSM-2020 is a miniature, two-channel Class D car amplifier measuring just 110mm (length) x 92mm (width) x 45mm (height). This significantly reduces installation space and is ideal for installation in confined areas such as under the dashboard, next to seats, or other discreet locations, while still delivering excellent performance. Its wide frequency response, covering 20Hz to 20kHz, faithfully reproduces rich details from bass to treble, satisfying the needs of a wide range of musical styles. The amplifier supports high- and low-level input switching for robust compatibility, making it easily compatible with both original audio sources and external devices. A signal-sensing function enables automatic power-on, and a built-in 12V remote output facilitates control and integration with other devices.

NSM-4020 4-channel mini-size class D amplifier delivers 20W RMS power per channel into a 4-ohm load. Leveraging efficient Class D amplification technology, the NSM-4020 not only delivers stable power performance but also effectively reduces energy consumption and heat generation, extending device life and reliability. It supports high-level and low-level input switching, offering excellent compatibility, making it easy to connect to both the original vehicle audio system and external audio sources. Equipped with adjustable high-pass filters (HPF) and low-pass filters (LPF), users can freely adjust the audio frequency range to suit different speaker types and listening preferences, achieving precise crossover and sound optimization, enhancing overall audio performance. A wide input sensitivity range (200mV to 9V) facilitates matching with various signal sources to meet the needs of different vehicle audio systems. A signal-sensing auto-start function ensures hands-free power-up, enhancing user convenience.

NSM-2120 2-Channel mini-size class D amplifier is a high-performance, miniature, two-channel Class D car amplifier. It offers stable operation with a 2-ohm load and excellent system adaptability, meeting the needs of even the most complex audio systems. It supports high-level and low-level input switching, compatible with a variety of original vehicle or external audio sources, and offers flexible and convenient installation. Built-in adjustable high-pass filters (HPF) and low-pass filters (LPF) allow users to freely adjust the frequency response based on speaker characteristics and audio layout, achieving precise crossover and optimizing overall sound performance. Independent gain control for both front and rear channels allows users to fine-tune the volume of each channel to create a balanced, harmonious sound field. A 12V remote output facilitates linkage control with other audio equipment, expanding system functionality. Multiple protection mechanisms, including short-circuit, overheating, and overload protection, ensure the safety and stability of the amplifier and vehicle circuitry, enhancing durability.

AM-2015 is a compact, two-channel, IC-class A/B car amplifier designed for small audio systems and space-constrained environments. It's ideal for driving low-power speakers and meeting everyday audio needs. Its wide frequency response, covering 20Hz to 20kHz, accommodates a wide range of musical styles. The amplifier supports high-level and low-level input switching, making it compatible with a wide range of in-car audio sources, whether used with original head units or retrofitted audio equipment. Built-in fixed high-pass filters (HPF) and low-pass filters (LPF) effectively separate the audio frequency bands, ensuring clean sound and preventing interference caused by frequency overlap. With an input sensitivity range of 200mV to 9V, it supports a wide range of signal strengths, facilitating connection and adjustment for diverse devices. Independent gain controls for both the front and rear channels allow users to adjust the volume for customized sound balance and fine-tuning.
