4 Channel Line Output Converter RCA Output

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.

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.

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.

NSLBT-2 is a high-performance Bluetooth receiver designed for automotive, marine, and various audio systems. It offers high-quality audio output and multi-source compatibility, making it an ideal choice for building wireless audio systems. Supporting dual input modes for Bluetooth signals and head unit output, it flexibly adapts to various audio sources to meet diverse installation environments and user needs. The NSLBT-2 utilizes standard RCA output connectors with a high output level of up to 3V, capable of directly driving most power amplifiers, ensuring a stable, clear signal and effectively reproducing high-fidelity sound. Its powerful Bluetooth reception enables wireless music playback, making it easy to upgrade traditional audio systems to modern wireless entertainment platforms and significantly enhancing the overall audio experience. Measuring only 75mm (length) x 55mm (width) x 28mm (height), the receiver's compact design makes it suitable for installation in a variety of spaces, including vehicle consoles, marine instrument panels, and audio equipment cabinets. It takes up no additional space, facilitating integrated and concealed installation. It offers a simpler wiring solution, reducing the clutter of cables in traditional audio systems.

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%. This ensures clear, detailed, and dynamic sound, meeting the high-fidelity and high-power requirements of multi-channel systems. A DIP switch allows for flexible crossover mode selection. The built-in low-pass filter (LPF) supports 120Hz and 80Hz settings, while a high-pass filter (HPF) is adjustable from 50Hz to 250Hz for 2-channel operation, allowing precise adjustment to suit speaker and system requirements, enhancing overall audio performance.
