The PC4 EVO is the top model of the GigaWatt power conditioners line. This reference device is dedicated to powering Hiend audio and video systems. PC4 EVO is the quintessence of many years of experience, research and work on an uncompromised power conditioner. This powerfull device came to life using newest technologies and specialized components. 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 construction of the PC4 EVO we resigned from using separation transformers and applied a worked out, multistage, parallel filtration instead. The conditioner is equipped with three independent filtering branches, separate for each quartet 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. PC4 EVO is based on a new architecture of filters and uses more advanced and excessive sized components. Due to the increased efficiency of the new filtering circuits they were mounted using silver solder on massive PCBs with fifteenfold content of copper compared to standard PCB. The two layered PCBs have very wide conductive traces made from 550 micrometer thick silver plated copper. Damping of the interference is made in RLC type filtering blocks, built using, among other things, metallized polyester capacitors with low inductance and HF (HighFlux) 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, nextgenerations of UltraMOV varistors and an initial filter. Protection against overload is provided by a hydraulicmagnetic switch made by the company Carling Technologies, which is made in USA on special order and to GigaWatt specification. This element controls the value of the current flowing through the internal circuits of the conditioner and serves as the main power switch. All those elements, working together with a welldesigned, modern power grid, warrant a complex protection against overcurrent and overvoltage. The internal elements of the PC4 EVO conditioner allow for a continuous load of 25A (and 70A peak), if the power line allows. This huge reserve is not necessary for lossless transfer of energy from the power line to the load, but to have a current reserve for impulse loads. A current reserve is a fundamental thing when supplying current to power amplifiers, capable of peak loads many times higher than their nominal values. A professional PowerCon 32 Amp socket, with silver plated pins, capable of sustained load of 32A, was used as the main powerin connector. Continuous load capability of this conditioner at 25A is almost triple of what a typical unit, utilizing an IEC socket, is able to provide. Optionally, the power conditioner can be equipped with the circuit, which eliminates unwanted DC component from the mains (DC Offset Blocker). The Direct Current component (DC Offset) is a very unfavorable phenomenon, which exists in almost every electrical grid. It results in the Alternating Current (AC) sine wave become asymmetrical, what negatively influences any device using transformers. Their cores get magnetized, what translates in higher operating noise (hum), diminished efficiency of the power supply and finally in degraded sound. The DC blocker effectively eliminates this phenomenon without causing any compression or having any other negative influence on the sound. The effective input voltage (True RMS) is indicated by a precise, digital voltmeter with a red LED display mounted in the front panel. This voltmeter is characterized by resistance to distortion and a measurement error caused by higher harmonics, and does not generate any interference on its own, which could worsen the quality of power filtered by the conditioner. On special order other colors of the display are available: green and blue. 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 PC4 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 from polished, high purity, silver plated cathode copper slabs (CuOF). 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 crimped and screwtightened connections and cabling made from silver plated OFC copper wires in FEP Teflon insulation with a crosssection of 4 QMM. The use of the star wiring topology and the high conductance and massive crosssection of about 45 QMM 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 PC4 EVO is equipped with a double buffering circuit with compensation cells with ultrahigh capacity and Power Factor Improvement System. This circuit improves the impulse response with nonlinear 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 PC4 EVO conditioner is equipped with twelve high quality power sockets GigaWatt G040 Schuko, designed and manufactured by the company. The brass connectors of those sockets were silver plated at the factory, without the usage 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 G040 sockets were equipped with integrated antisurge shutters (increased protection against touching, conform to VDE 0620). The PC4 EVO is also available with outlets of type NEMA 520R, used in North America and some Asian countries, and with Australian outlets of type AS/NZS 3112. All internal elements of the conditioner were enclosed in a ultrarigid, nonmagnetic chassis made from austenitic stainless steel. To reduce the vibration transferred on the conditioner its cabinet is additionally damped with a bitumenpolymer composite mattes, and the whole is supported on massive, antivibration feet made from solid aluminum. The front of the unit is made from a plate of solid, milled aviation aluminum. This panel, with brushed and anodized surface is available in two colors – silver and black.
