4 Channel Line Output Converter

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-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.

LEB-2 is a two-channel high-level to low-level signal converter designed specifically for upgrading car audio systems. Featuring high-level input and RCA output, it easily converts high-level audio signals from the original head unit or amplifier into standard RCA low-level signals, providing clean, stable audio input for power amplifiers, DSPs, or audio equipment, significantly improving sound quality and system compatibility. This high-level input is suitable for head units or OEM audio systems without RCA outputs, allowing users to easily expand their audio systems without replacing the head unit. The LEB-2 features a built-in gain control knob to precisely adjust the output level based on the output voltage of different head units, ensuring optimal matching with amplifiers and other devices, effectively preventing distortion and level mismatches.

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.

NSLBM-4120 4-channel full-range class D amplifier is IPX5-rated for waterproofing and features a rugged mechanical structure (ME structure) that withstands diverse environments, ensuring safe and stable operation in damp and dusty conditions. It is particularly suitable for outdoor audio and automotive applications. The NSLBM-4120 delivers 80W RMS power per channel into a 4-ohm load, increasing to 120W RMS into a 2-ohm load, with distortion below 1%.
