●Maximum input level 10VP-P ●Frequency characteristics 20 to 40,000Hz±1dB ●Input terminal Gold-plated RCA jack ●Output terminal Gold-plated RCA jack ●External dimensions approx. 80mm x 40mm x 25mm (main unit only)

●By connecting between the audio line cables, it is possible to prevent alternator noise synchronized with engine rotation while driving. ●In the case of a complex system that connects a deck, amplifier, network, equalizer, etc., there will be differences in ground potential between each device, making alternator noise more likely to occur. In such cases, the NF-1A's noise filter is effective. ●High quality design using a high performance transformer with low noise and frequency response within ±1dB from 20 to 40,000Hz. ●Removes alternator noise caused by ground potential difference between lines of audio equipment. ● Robust and beautiful aluminum body that is resistant to external noise. ●The printed circuit board uses a glass epoxy printed circuit board that is resistant to moisture and water leakage and exhibits the highest insulation resistance. *Please check the compatibility information before purchasing. Precautions for use *Although it effectively removes noise caused by ground potential difference, it does not remove all noise. Safety Warning *Do not disassemble or modify this product. *Please note that incorrect installation, connection, or use of this product may cause damage or damage to the vehicle, and we cannot be held responsible for such damage. *We do not provide any support for installation or warranty of this product on illegally modified cars, poorly maintained cars, etc. Read more
