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👍🏻👍🏻

Average low pass filter when you look at the signal gain
With the increased gain the signal gets distorted pretty quickly. Low frequency selector does not work. High frequency tops at 80hz before tapperring down. With 400mv signal. The undistorted gain is about 4x. More importantly, the output signal is reversed. 180 degree phase shift to original signal...
