The LEB-2's output uses standard two-channel RCA connectors, making it compatible with mainstream amplifiers and audio processors. Its compact body design, measuring 78mm (width) x 94mm (length) x 45mm (height), makes it easy to install in narrow spaces such as under the car dashboard, under the seat or in the trunk, suitable for the concealed wiring needs of various car models.

LEB-4 is a four-channel high-level to low-level signal converter designed specifically for upgrading car audio systems. Featuring high-level inputs and standard RCA outputs, it effectively bridges the gap between the original head unit and aftermarket amplifiers, DSPs, and other audio devices, providing the foundation for building a higher-quality audio system. Supporting four channels of high-level audio signal input, it easily adapts to most original head units or OEM audio systems, allowing users to upgrade their audio systems without replacing the head unit. The LEB-4's output uses standard four-channel RCA connectors, making it compatible with a wide range of amplifiers and digital processing devices on the market, ensuring stable and clear audio signal transmission and significantly improving overall sound quality. A built-in gain adjustment knob allows users to precisely adjust the output level of the original vehicle audio to match the input requirements of the power amplifier, avoiding distortion caused by excessive signal strength or low volume caused by insufficient signal strength. This adjustable design not only improves system compatibility but also facilitates installers and testers to achieve more professional tuning results.

LEBR-4 is a powerful 4-channel high-level to low-level output converter. It not only provides standard high-level inputs and RCA outputs, but also features independent gain adjustment and remote start outputs. This ensures high-quality, stable audio and control signals are delivered to downstream audio devices, such as amplifiers or DSPs, while preserving the original vehicle head unit. This product supports four high-level audio inputs, perfectly matching the output signals of the original vehicle head unit or OEM audio system, allowing you to fully upgrade your audio system without replacing the original head unit. Four RCA outputs connect to a multi-channel amplifier or audio processor, ensuring clear and balanced signal output and minimizing audio loss. Built-in level and gain adjustment allows each output to be individually fine-tuned, allowing installers to precisely match the input levels of different brands or models of downstream audio devices for optimal sound quality and improved overall audio performance. The LEBR-4 features a Remote Turn Out function that automatically activates the power amplifier or other devices upon detecting a high-level audio signal input, eliminating the cumbersome wiring of traditional wired start-ups and enhancing system automation and cleanliness. This feature is particularly useful for those who prefer to conceal their amplifier installation to maintain a clean and aesthetically pleasing interior.

NSLOC21 is a versatile two-channel audio signal amplifier and converter, integrating a high- and low-level signal converter and line driver, specifically designed for upgrading modern car audio systems. It not only supports high-level inputs up to 40V but also features built-in high-quality RCA outputs, enabling efficient connection to power amplifiers or audio processors for high-fidelity audio transmission. The NSLOC21 supports a variety of audio source inputs and features a signal-sensing start function. Upon detecting an audio input, it automatically activates the remote control output, providing a stable start signal for amplifiers or other devices, significantly enhancing system intelligence and ease of use. This feature is particularly useful for original head units without a REM output, eliminating cumbersome wiring and manual control. The product's sophisticated high- and low-level conversion function accepts high-level audio signals up to 40V at the input, offering high compatibility with a wide range of head unit output specifications. Whether using an OEM head unit or aftermarket audio device, the NSLOC21 smoothly converts the signal to a standard RCA output, effectively improving audio signal consistency and stability.

NSXP-2120 is a high-performance, two-channel Class D car amplifier designed for in-car audio systems that demand clear sound quality and space-saving features. This two-channel Class D amplifier delivers 2 x 70W RMS power into a 4-ohm load and 2 x 120W RMS into a 2-ohm load, with total harmonic distortion (THD) kept to less than 1%, ensuring pure, dynamic sound. It's ideal for driving mid-range and high-frequency speakers, delivering a more three-dimensional and natural musical performance. It can be conveniently installed concealed under a car seat or in the trunk, minimizing space and providing greater installation flexibility for limited interior space. It supports both RCA low-level and high-level inputs, and an input level selector switch allows for easy integration with both original and modified head units, further enhancing compatibility.

NSLC3 is a powerful two-channel high-low level converter designed to enhance the performance of in-car audio systems. It not only supports speaker inputs up to 400W RMS, but also features integrated digital bass enhancement, significantly improving low-frequency performance for a more powerful and rich sound experience. Whether you're upgrading your stock car audio system or building a professional-grade audio system, the NSLC3 can meet your needs. The device features precise bass compensation and volume matching controls, allowing you to flexibly adjust the sound quality to suit your vehicle and audio configuration, ensuring a more balanced and natural sound output. Built-in 9.5V pre-out and 12V trigger outputs enable seamless integration with a variety of amplifiers, facilitating the expansion and management of multi-stage audio systems. The NSLC3 also features an optional dashboard-mounted remote control, allowing users to easily adjust bass level from the driver's seat for real-time listening experience and enhanced driving pleasure.
