ART PS4x4 Pro B-Stock - 1800W FILTERED POWER DISTRIBUTOR

(This text is machine translated) All PRO series models have an additional discrete internal module called APF (Advanced Filtering Power) which digitally filters and hashed dimmers as well as any high frequency noise that is above the audio range. Some off-the-shelf add-on modules saturate and lose their filtering effectiveness as the load increases, but by using a discrete high-power design we were able to create a filter that remains acting over the entire full operating range. By using the Common Mode and Differential Mode topologies in series for the filter design, the Art is able to block virtually all unwanted noise that is between the AC line and ground, and also between the two sides of the AC line. This has the added benefit of reducing ground loop problems in the system. High frequency noise currents, in particular, are strongly attenuated in both directions so that any line noise generated by one of the components cannot go back into the main AC, so if you are using a series of Pro Series power ...
