NSLOC81 is a high-performance 8-channel high- and low-level converter designed specifically for multi-channel audio system conversions. It features an integrated AUX input and offers a variety of professional features, including channel summing, independent channel adjustment, signal-sensing start, remote output, and peak level indication. It is ideal for seamlessly integrating OEM head units with high-end aftermarket amplifiers or DSP systems. Supporting up to eight high-level audio inputs, it efficiently converts high-level signals from the original head unit or center console into standard RCA low-level signals. It also features channel summing, ideal for applications where the original audio source has split frequency bands (such as separate door speakers and tweeters). By combining the signals, the NSLOC81 outputs a full-band signal, providing a more accurate and complete audio foundation for downstream amplifiers. Each channel features independent input gain adjustment, allowing users to fine-tune channel levels based on the actual source output level and system configuration, ensuring signal matching across the system and enhancing overall sound balance. The device is also equipped with a MAX level indicator light, which can intuitively reflect whether the signal has reached saturation, effectively preventing overload distortion and helping users quickly complete accurate debugging.

LEBR-2 is a high-performance, two-channel, high-level to low-level signal converter designed specifically for car audio system upgrades. It features not only high-level input and RCA output, but also a practical built-in remote output function, greatly facilitating expansion of power amplifiers or audio equipment. It is an ideal bridge between the original car audio system and upgraded audio systems.

The LEBR-2 safely converts high-level signals from the original head unit or audio system to standard RCA low-level outputs, making it compatible with a wide range of aftermarket amplifiers, DSPs, and other audio equipment. A built-in gain adjustment knob allows users to fine-tune the level according to varying signal strengths, achieving precise matching between systems and effectively improving sound quality while avoiding distortion or equipment damage caused by inappropriate input levels. A key feature of this product is its remote control output function. Triggered by a high-level signal, the LEBR-2 automatically outputs 12V upon detecting an audio signal. This voltage can be used to activate power amplifiers or other audio equipment requiring remote control, eliminating cumbersome wiring and enhancing system intelligence.
