Best Low pass filter For such a low price.
This is the best low pass filter for such a low price. It works on 12+ 0 12- supply can also work on 24+ 0 24- supply! It can be the best low pass filter if u know how to use it properly without overdriving it. It doesn't heat up also it has no power led so yea u will not understand if the low pass filter is powered on. Also the solder pads are kind of small so solder the wires properly without shorting, if u don't connect Gnd near the audio input area properly, hiss of humming sound can occur. LOVE THIS PRODUCT , GOOD ENOUGH TO MOVE A 12INCH SUB👍🏻👍🏻

LM324N instead of TL074
They tricked us by rubbing off the part number. For cost cutting they have used LM324N (it was partly rubbed off, but a little bit of IPA revealed everything lol ) instead of TL082 (shown in the image). the PCB is good quality, before using just replace this IC with a genuine TL074 for low distortion and better audio, it will work perfectly.
