The PS 4x4 boasts a backlit linear meter for monitoring input voltage, offering a familiar analog readout. It also features a backlit linear Ammeter displaying Load Current in amperes, providing a real-world look at power consumption. While the voltmeter remains relatively stable, the ammeter fluctuates more, indicating power usage. In a rack with digital equipment, the ammeter may not vary much, but with power amps, it can bounce around, showing output. The PS 4x4 includes ART's 4x4 distribution on the back, allowing for wide power cables and multiple wall wart devices, while still offering eight total power outlets.
It comes with a one-year manufacturer's warranty.
