The ART SP 4x4 Rackmount 8 Outlet Power Conditioner is a low-cost AC power solution for rackmount systems. The SP 4x4 can be installed into the top slot of a rack, and the eight switched AC outlets in the rear panel will power up and protect all your equipment, up to a 15A load. The backlit linear voltage meter displays incoming voltage, and the two slide-out, swiveling light fixtures provide illumination for all your gear. They are adjustable via the front-panel dimmer control.
The SP 4x4 conditions your delicate electronic equipment with a high-voltage surge and transient suppressor and an RFI/EMI interference filter. The fast-acting suppression circuit responds in less than a nanosecond, clamping transient voltages to safe levels. The filter works to prevent noise from fluorescent lights, certain dimmers, radio transmitters, and similar sources of "electronic pollution" from entering the AC line, and, from there, leaking into sensitive audio, video, or computer circuits.
The SP 4x4 also features ART's "4x4" distribution on the back of the unit - four of the eight rear outputs are 1.25" apart. This allows the user to plug in wide power cables and multiple wall wart devices, and still have eight total power outlets to choose from.
