The high-quality power filter for car audio, the Nve-03, provides a stable power supply. - Brand: KOJO TECHNOLOGY - Model Name: Nve-03 - Input Voltage: +12V - Output: GND - Additional Features: ADD VE - Retail Price: 42,900 yen (tax included) Previously, power filters for car audio were mainly formed with a composite circuit of large-capacity electrolytic capacitors and choke coils. These have greatly contributed to and acted upon battery voltage fluctuations and relatively low (noise) frequency bands. Battery voltage fluctuations affect the stable operation of in-vehicle electronic devices, and in the case of car audio equipment, they have a significant impact on sound quality. This continues to be a market need even now. On the other hand, with the digitalization of various electronic devices installed in vehicles, including recent car audio equipment, the inside of the car is overflowing with various high-frequency noise. The "Nve-03" released this time is designed to address this high-frequency noise by arranging film capacitors with excellent high-frequency characteristics by capacity (reducing high-frequency impedance) and suppressing and attenuating noise generated from inverters, switching power supplies, internal clocks, etc. In addition, it is a new concept conditioner "Pure Condimenta" that also incorporates our virtual earth technology function. It also reduces body ground (GND) noise.
