SoundNex Car Audio High to Low Converter Noise Reduction Module

SoundNex Car Audio High to Low Converter Noise Reduction Module

Optimize your in-car sound system with the SoundNex High-to-Low Converter, designed to transform high-level speaker outputs into low-level RCA signals for amplifiers and subwoofers. This essential device ensures clear, balanced, and noise-free signal transmission for powerful audio performance.

The converter is available in two types — passive and active. The passive version works as an attenuator, requiring no power connection, while the active version features an internal amplifier circuit for cleaner, enhanced sound output. Some active models also include adjustable volume controls, providing greater flexibility in tuning your system.

Ideal for vehicles without factory RCA outputs, the SoundNex converter allows easy integration of aftermarket amplifiers without compromising sound quality. Compact, reliable, and easy to install, it’s the perfect upgrade for audiophiles seeking superior in-car sound performance.

The role of car audio high to low

1. High to low: Used to convert the high-level audio voltage output by the speaker into a low-level audio signal for input by other power amplifiers.

2. Common "high to low" converters are roughly divided into passive and active types. Passive high-to-low does not need to be connected to the battery. The high signal has recently gone out, and the middle is a few resistors. So to be precise, passive high to low should be called an attenuator. Active high-to-low requires battery power supply. The high signal is converted into a low signal through an amplifier circuit. It belongs to an audio amplifier that plays a role of reduction. Some active high-to-low with volume adjustment are actually the principle of the power amplifier.

3. It is not necessary to use high-to-low in the audio system. Only when the original car host does not have RCA output, you can consider installing a high-to-low to solve this problem, but the ordinary high-to-low will be Some audio signals are lost.
