Product Description

Presenting the 4x4 pro series power distribution system from Art. Built on the foundation of the popular 4x4s, the SP4x4 Pro is a durably constructed reliable power conditioner that can be used in many applications. Wherever power management system is required, the 4x4 pro series provide the surge protection you need to keep your rack safe from unwanted disruption. The SP4x4 Pro has an additional internal discrete module called APF (Advanced Power Filtering) which filters out digital and dimmer hash 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 high power discrete design we were able to create a filter that stays effective over the full operating range. By using both Common Mode and Differential Mode topologies in series for the filter design we are able to block virtually all of the unwanted noise that is between the AC line and ground, and also the two sides of the AC line. This has the additional benefit of reducing ground loop problems in your system. High frequency noise currents in particular are highly attenuated in both directions so any line noise that could be generated by one of your components is not allowed to get back into your main A.C. wiring so if you use a number of PRO SERIES Power Conditioners in your setup, you can distribute and isolate the noisy components from the sensitive components in your system.
