Product Description

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.
