Filter 20K

8-channel passive low-pass filter, mainly used for audio measurement of Class-D amplifier. It can provide audio out of band attenuation and reduce the steepness of fast conversion edges, providing signal preprocessing for testing accuracy. It has a passband of 20-20kHz and is designed specifically for use with the A8 series audio analyzers.
