Presenting the 4x4 PRO USB SERIES Power Distribution Systems from ART. Built on the foundation of the popular 4x4s, the PRO USB SERIES are durably constructed, reliable power conditioners for use in many applications. Wherever power management system is required, the 4x4 PRO USB SERIES provides the surge protection you need to keep your rack safe from unwanted disruption.
All PRO USB SERIES models have 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 that 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 USB SERIES Power Conditioners in your setup, you can distribute and isolate the noisy components from the sensitive components in your system. Additionally, any signals above 10kHz are filtered from the line with over 40dB of attenuation above 100kHz and beyond.

The ART 4x4 PRO SERIES Power Distribution Systems also protect your delicate electronic equipment with high voltage varistor (MOV) surge and transient suppressors. The fast-acting suppression circuit responds in less than a nanosecond, clamping transient voltages to safe levels.
The eight circuit breaker protected outlets are rated at 15 amps total, which is equivalent to 1800 watts at 120 volts. If the total load on the 4x4 PRO Series Power Distribution System's outlets (and rack lights on the SP4x4 PRO & PS4x4 PRO) exceeds 15 amps, the circuit breaker will trip, cutting off power to your rack. If this happens, reduce the load by unplugging one or more units from the unit, then push the circuit breaker button in to reset it.
The 4x4 PRO Series Power Distribution Unit's lamps pull out easily and may be aimed to provide the best illumination for your equipment. Adjust the DIMMER control for the desired brightness. You should set the RACK LIGHTS switch to the OFF position if not using the lights for an extended period of time.
