PRODUCTS CENTER
Dual channel multipole LRC passive low-pass filter, mainly used for audio measurement of Class D amplifiers. It can provide out of band attenuation for audio and reduce the steepness of fast transition edges, providing signal preprocessing for testing accuracy, with a passband of 20-40kHz.
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.
Audio switch box, used to expand the input/output capability of dual-channel audio analyzers. It can extend 2 input/output channels to any two of the 12 input/output channels, avoiding the need for cable plugging and unplugging due to interface changes during multi-channel product testing, thereby improving testing efficiency.
Used in conjunction with an audio switch to provide interface conversion between the audio switch and the testing computer.
