Audio Isolation Noise Reduction Module – Car & Home Systems

Q: What does the Audio Isolation Noise Reduction Module do?

This module uses active audio isolation technology to remove ground-loop hum and unwanted signal interference from your audio chain. It ensures a stable, clean signal path between your audio source and amplifiers — whether in a car audio system, home stereo, or DSP setup — resulting in noticeably cleaner, clearer sound.

Q: What input and output connections does this module support?

The module features a 3.5mm input and a 3P 2.54mm terminal input, along with two 3.5mm outputs and two 3P 2.54mm terminal outputs. This versatile configuration lets you connect to multiple amplifiers simultaneously and integrate with a wide range of audio devices and systems.

Q: Is this module suitable for car audio installations?

Yes — the wide operating voltage range (DC 4–18V) and broad temperature tolerance (-30°C to +85°C) make it well-suited for automotive environments. Its compact size also makes it easy to fit within tight spaces in a vehicle's audio setup.

Q: What is the noise floor and distortion level of this module?

This module achieves a noise floor of -105dB and total harmonic distortion of less than 0.002%, making it ideal for high-fidelity audio applications where signal purity is critical.
