Power Quest 303

AudioQuest PowerQuest 303

The AudioQuest PowerQuest 303 is a mains filtering model that can be mounted in a rack or set up free-standing in a hi-fi system. This PowerQuest 303 utilizes AudioQuest's comprehensive approach to AC power conditioning, addressing noise linearly to provide industry-leading noise cancellation over a wide frequency range (better than -22dB).

The PowerQuest 303's linear noise dissipation includes differential mode filtering (30 kHz - 1 GHz), which addresses asymmetric noise already present on the power line or backwashed through electronic devices and components.

Protection guaranteed The PQ303 is equipped with non-sacrificial overvoltage protection and automatic shutdown under extreme voltage. If excessive surge voltage is present on the incoming AC line for more than a quarter of a second, the circuit will immediately open a high current relay which will shut off AC power to all PowerQuest outlets, causing the red LED on the front panel is activated, the overvoltage protection warning indicator. Once the event is over or the wiring fault is resolved, the circuit will automatically turn back on. So you can rest assured that your valuable connected equipment is well protected.
