ART PB4X4PROUSB Power Distribution System The PB4x4 Pro USB features eight rear AC outlets, four of which are widely spaced to accommodate large power supplies, with surge and spike protection to keep your equipment safe. Pro USB models add an unswitched front AC outlet, two 5-volt USB ports, a rear gooseneck lamp, and our Advanced Power Filtering (APF) module. APF filters digital and dimmer hash, and any high-frequency noise above the audio range. The custom filter design blocks virtually all unwanted signals between the AC line and ground. This augments the EMI and RFI filtering found in every ART rackmount power supply, providing our most sophisticated power conditioning. Power your rig with a convenient single switch and give your equipment the protection it deserves.
