GigaWatt PC-2 EVO+ Power Conditioner
PC-2 EVO+ is a high quality power conditioner with inbuilt DC Blocker, designed to power and protect HI-END audio-video systems.
AU sockets
This conditioner not only effectively protects from any kind of interference and overvoltage in the power grid, but most of all warrants visible improvement of the sound and picture quality in the powered devices. The unit excels with a solid construction, usage of selected components and high quality and aesthetics of workmanship.
In the modular construction of the PC-2 EVO+ we resigned from using separation transformers and applied a worked out, multi-stage, parallel filtration instead. The conditioner is equipped with three independent filtering branches, separate for each pair of output sockets. Due to this solution the filtration of each of the branches was adapted to the character of the load, that will be used on those sockets, different for each kind of devices – digital, analog or high current draw units. The autonomous passive filters allow for isolation from interference generated by devices connected to a common power line.
The PC-2 EVO+ conditioner is made of high quality elements. Due to the increased efficiency of the new filtering circuits they were mounted using silver solder on massive PCBs with double-fold content of copper compared to standard PCB. The one layered PCBs have very wide conductive traces made of 70 micrometer thick copper. Damping of the interference is made in RLC type filtering blocks, built using, among other things, metallized polyester capacitors with low inductance and IP (Iron Powder) core filters.
In this conditioner we also resigned from using traditional protective elements, like wire or thermal fuses, which throttle the free flow of current to the protected circuits and by this have a negative influence on the sound. The overvoltage protection of the conditioner is guaranteed by the start block, which contains plasma spark gaps, next-generations of TMOV varistors and an initial filter. Those elements, working together with a well designed, modern power grid, warrant a complex protection against overcurrent and overvoltage.
Proper operation of the unit is signaled by a blue LED mounted in the front panel. The conditioner is also equipped with an additional circuit, signaling problems with its connection to the power grid. A red LED mounted on the back signals improper polarization of the power fed to the conditioner or bad connection of the grounding.
The PC-2 EVO+ uses an innovative, two stage current distribution system, being a proprietary development of the company. It is based on massive power distribution bars of 2nd generation, made of polished, high purity, cathode copper slabs (Cu-ETP). The first stage allows for lossless and equal distribution of power to the individual filtering branches. The second stage supplies power directly to each pair of output sockets, using clamped and screw-tightened connections and cabling made of electrolytic copper with a cross-section of 2.5QMM. The use of the star wiring topology and the high conductance and massive cross-section of about 30QMM of each of the bars warrants an equal and stable power distribution regardless of the load on any of the conditioner’s outputs.
To allow for the highest possible impulse response the PC-2 EVO+ is equipped with a double buffering circuit with compensation cells. This circuit improves the impulse response with non-linear loads, like for example power amplifiers, and levels the difference between input and output power of the conditioner, allowing for almost unlimited impulse capabilities.
The PC-2 EVO+ conditioner is equipped with six high quality power sockets GigaWatt G-040 Schuko, designed and manufactured by the company. The brass connectors, those sockets were silver plated at the factory without the use of intermediary metals like copper or nickel, which could introduce unfavorable series resistance and voltage loss. The increased area of contact and the thick layer of silver guarantee sure contact with the plug pins. The sockets were additionally subdued to cryogenic modification and a demagnetizing process. In order to effectively protect children, the G-040 sockets were equipped with integrated anti-surge shutters (increased protection against touching, conform with VDE 0620). The PC-2 EVO+ is also available with power sockets of type NEMA, used in USA and some Asian countries.
All internal elements of the conditioner were enclosed in a rigid, steel-aluminum chassis, which is supported on anti-vibration feet. The front of the unit is made of a plate of solid, milled aviation aluminum. This panel, with brushed and anodized surface is available in two colors – silver and black.
The PC-2 EVO+ is equipped with a 1.5m LC-1 EVO power cable.
