【AT-NF200 Line Noise Filter｜For Noise Countermeasures for Car Audio】

If you hear noise such as “buzz” or “hueen” from your car audio, one possible cause is noise that has found its way into the audio signal line. AT-NF200 is a line noise filter designed to reduce noise entering the audio signal line of your car audio system.

It’s used on the audio signal line to address symptoms such as noise that prevents you from focusing on music, sound that changes in sync with engine RPM, or noise that starts after adding a system. With its robust metal body, it also features a compact size designed for installation inside the vehicle.

However, the source of the noise varies depending on factors such as the vehicle’s power supply, grounding, the routing of the wiring, and the connected equipment. Since simply adding a filter does not always guarantee a fix, it’s important to first check the symptoms and choose a method that matches the cause. If it were me, I would use it in the necessary place after actually confirming the sound, rather than adding components right away.

At LOGON, we are not only here to consult you about the AT-NF200 by itself, but also to consider the overall direction for your noise countermeasures while looking at combinations with your existing car audio system and any added equipment. Since you put together your system to improve the sound in the first place, let’s not leave the noise you’re concerned about as-is—let’s check it together once.
