Until now, power filters for car audio have mainly been formed by composite circuits with high-capacity electrolytic capacitors and choke coils.
These have contributed significantly to battery voltage fluctuations and relatively low (noise) frequency bands. Battery voltage fluctuations affect the stable operation of automotive electronic equipment, and have a significant impact on sound quality in car audio equipment. This is still a continuous market need.
On the other hand, hybrids and EVs have arrived in the automotive industry in recent years. Various control electronic devices installed in vehicles, including car audio equipment, are becoming more digital, and the interior of the car is overflowing with various high-frequency noises.

In order to cope with such high-frequency noise, the N-04 is designed to suppress and attenuate high-frequency noise generated by inverters, switching power supplies, and internal clocks by arranging film capacitors with excellent high-frequency characteristics by capacitance (reducing high-frequency impedance).
In addition, when used in conjunction with the popular BODY Earth Enhancement BOX: ve-02 (including the old VE-01), you can expect to further improve sound quality.

KOJO Power Filter N-04

  • he N in the model name "N-04" refers to the noise filter installed inside.
    The TOP cover is made of black anodized aluminum, and the BOTTOM chassis is finished with a satin-like black paint finish, giving it a heavy, robust, and luxurious feel.
    In addition, in order to improve visibility of the polarity of the power input and output terminal blocks, we painted the ▲:INPUT and ▼:OUTPUT marks that image the flow of electricity.

    The N-04 power filter for car audio has been awarded the title of "CREATIVE POWER ACCESSORIE" as a creative power accessory typical of KOJO TECHNOLOGY.
