This is the ART PS4x4PRO “POWER STATION“ Power Distribution System with Dual LED Metering.
Also known as a Power Conditioner, the PS4x4PRO Power Distribution System features APF™ Advanced Power Filtering, a Rear BNC for a lamp and is housed in a durable & solid rack mount chassis.
The PS4x4 features a backlit linear meter to monitor input voltage, which gives the user a familiar analog style readout when monitoring voltage from a power source. The PS4×4 has a backlit linear Ammeter showing Load Current in amperes. This additional meter gives an analog “real-world” look at how much power you are using; hence the term “Power Station”.
Applications for the PS4×4 include: Live Sound Systems/PA, Permanent or Fixed Installations, Church, Club and Practice PA Systems, DJ Sound Systems, Home and Project Recording Systems, and Monitor Systems.
