GigaWatt PC-4 EVO+
GigaWatt parallel multi-branch filtering mains conditioner, designed to power high-end audio and video installations.
Description
The PC-4 EVO+ is a power conditioner designed to power high-end audio and video systems. It is placed between the domestic mains supply and hi-fi or home cinema equipment in order to filter out disturbances present on the line and protect the installation against mains fluctuations.
This conditioner is based on a multi-stage parallel filtering architecture, without an isolation transformer. It has three independent filtering branches, each dedicated to a quartet of output sockets: this separation allows the filtering to be adapted to the nature of the connected load, whether it is a digital, analogue or heavily current-consuming device. The filtering blocks are RLC type, built with low-inductance metallised polyester capacitors and HF core filters, silver-soldered onto solid printed circuit boards featuring 550-micron-thick silver-plated copper tracks.
Surge protection is provided by a starting block combining plasma spark gaps, UltraMOV varistors and an initial filter, without recourse to traditional thermal fuses. Overload protection relies on a hydraulic-magnetic circuit breaker manufactured by Carling Technologies to GigaWatt specifications, which also serves as the main power switch.
This conditioner is aimed at high-end audio and video installations comprising several sources or devices with differing electrical requirements, where separate filtering management per branch makes real sense. Its size and weight make it a unit intended for a fixed installation rather than portable use.

What to check before buying used
Check that the output sockets and mains connector are firmly secured and free of oxidation, as they are subjected to often-heavy cables. Test each of the three filtering branches with a real load to rule out any fault in the RLC blocks or the solder joints on the printed circuit boards. Examine the starting block: plasma spark gaps or varistors worn out by repeated surges lose effectiveness without this being visible from the outside. Inspecting the chassis (440 x 160 x 400 mm, 20.5 kg) also helps identify any impact that may have affected the internal wiring.
