Gigawatt PC-2 EVO+ med kabel

Gigawatt PC-2 EVO+ er en teknologisk avanceret, ny generation af power conditioner, designet til at drive og beskytte audio-video-systemer i Hi-Fi og Hi-End-klassen. Den beskytter ikke kun effektivt mod interferens og overspænding i hjemmets elnet, men garanterer også en betydelig forbedring af lydkvaliteten og det viste billede af de enheder, der er tilsluttet den.

Alle interne komponenter i strømrenseren er indkapslet i et robust stål-aluminium-chassis, som står på anti-vibrationsfødder fremstillet af massivt, anodiseret aluminium med et lag af proprietær elastomer på 3,5 mm tykkelse.

Frontpanelet på strømrenseren er lavet af et tykt stykke luftfartsgodkendt aluminium. Overfladen er børstet efter præcis fræsning og derefter anodiseret i enten sort eller sølv.

PC-2 EVO+ er udstyret med seks højkvalitets, proprietære GigaWatt-strømudtag med stor kontaktflade. Messingkontakterne i stikkene er sølvbelagte uden brug af mellemmetaller som kobber eller nikkel, som kunne introducere uønsket seriemodstand og spændingstab. Den forøgede kontaktflade og det tykke sølvlag sikrer god kontakt med stikbenene. Stikkene er desuden kryogenbehandlet og afmagnetiseret.

Korrekt drift af enheden vises af en hvid LED på frontpanelet, og en rød LED bagpå advarer om forkert tilslutning til elnettet, herunder fejl i polaritet eller jordforbindelse.

Tekniske løsninger

PC-2 EVO+ er udstyret med flertrins parallelfiltre. Tre uafhængige filtreringsgrene forsyner hver deres sektion, bestående af to strømudtag. Denne løsning gør det muligt at justere filtrering til den type belastning, der tilsluttes – digital, analog eller højstrøm. De autonome passive filtre isolerer effektivt forstyrrelser mellem enheder, der er tilsluttet den samme strømforsyning.

PC-2 EVO+ bruger en innovativ strømfordelingsarkitektur med massive tredjegenerations distributionsskinner fremstillet af poleret oxygenfri kobber (OFHCC 10100) med en renhed på 99,995%. Strømmen fordeles effektivt til hver filtreringsgren, og der leveres jævn strøm til alle udtag via boltfaste forbindelser og GigaWatt Powerlink-ledninger med et tværsnit på 4,0 QMM. Stjernetopologien sikrer en ensartet og stabil strømfordeling, uanset belastningen på de enkelte udtag.

For at sikre maksimal impulsrespons er PC-2 EVO+ udstyret med et dobbelt buffersystem med Audio Grade kompensationsbatterier, som øger strømkapaciteten ved ikke-lineære belastninger som effektforstærkere. Dette eliminerer forskelle i strøm mellem ind- og udgang og sikrer næsten ubegrænsede impulsmuligheder.

En standardkomponent i PC-2 EVO+ er DC Offset Blockeren, som eliminerer uønskede DC-komponenter i strømnettet. Denne DC-komponent påvirker alle enheder med transformatorer negativt og forringer effektiviteten og lydkvaliteten. DC Blockeren eliminerer dette fænomen uden at forringe lydkvaliteten.

Gigawatt PC-2 EVO+

All internal elements of the conditioner were enclosed in a rigid, steel-aluminum chassis, supported on anti-vibration feet made from solid, anodized aluminum, with a layer of proprietary elastomer 3.5mm thick.

The front panel of the conditioner is made from a thick slab of aviation grade aluminum. Its surface is brushed, after precision milling, and then anodized black or silver.

The PC-2 EVO+ has six, high quality proprietary GigaWatt power sockets, with large surface contacts. The brass contacts of the sockets were subdued to the process of technical silver plating without usage of intermediate metals, like copper or nickel, which could introduce an unfavorable serial resistance and a voltage loss. The increased surface of the contacts and the thick layer of silver guarantee good contact with the plug pins. The sockets were additionally cryogenically modified and de-magnetized.

Proper operation of the unit is indicated with a white LED mounted in a display in the middle of the fascia. The conditioner is also equipped with an additional circuit signaling wrong connection to the power grid. Its action is indicated by a red LED on the back of the unit, which signals wrong polarity of the device or faulty grounding.

TECHNICAL SOLUTIONS

The conditioner PC-2 EVO+ is equipped with multistage parallel filters. Three, independent filtering branches, which supply three sections, composed of two output sockets each. Due to this

solution the kind of  filtering was adjusted for the load it has, different for each type of devices – digital, analog or high current devices. Autonomous passive filters allow for isolation from interference produced by the devices connected together via a shared power line.

The PC-2 EVO+ is based on a novel filtering architecture and uses new components. The main novelty are the anti-interference capacitors and the compensation batteries for the buffering circuits, which are manufactured by the company Miflex, according to GigaWatt specification.

In the PC-2 EVO+ an innovative, two-stage current distribution system is used, a proprietary design of our company. It is based on massive third generation distribution rails, made from polished slabs of oxygen-free copper OFHCC 10100 with 99.995% purity. The first stage allows for lossless and even distribution of voltage to each of the filtering branches. The second stage provides current directly to each pair of output sockets via bolted and clamped connections as well as cabling with GigaWatt Powerlink conductors with 4.0 QMM cross-section made from oxygen-free copper. The star connection topology and high conductance combined with the 30 QMM cross-section of each of the rails allow for an uniform and stable power distribution regardless of the load on the individual outputs of the conditioner.

Due to the improved efficiency of the filtering circuits, they were mounted using silver solder on massive PCBs having twice the amount of copper compared to standard PCBs. The single layer PCBs have very wide traces made from silver plated copper, with a thickness of 70 micrometers. The interference is damped by filtering blocs of RLC type, built around proprietary Audio Grade capacitors and IP (Iron Powder) core filters.

In the conditioner there are no traditional protective elements, like thermal or blow fuses, which throttled the free flow of the current have a negative influence on the sound. The surge protection of the conditioner is provided by the starting block, which utilizes plasma spark-gaps, UltraMOV new generation varistors and an initial filter. All those elements working together with a well-made, contemporary power grid, guarantee a complex protection against surges and overcurrent.

To allow for the maximum impulse response, the PC-2 EVO+ is equipped with a double buffer circuit with Audio Grade compensation batteries, a proprietary design. The circuit increases the current output with non-linear loads, like power amplifiers, as well as eliminates the difference of power between the input and output of the conditioner. This allows for almost unlimited impulse capabilities, unheard of in other passive conditioners and not reachable for active conditioners. The impulse capabilities of the PC-2 EVO+ surpass even the values of clean power line without any devices connected to it.

The standard equipment of PC-2EVO+ is also DC Offset Blocker –  a circuit eliminating unwanted DC component of the power grid. This DC component is a very deteriorating phenomenon, which exists in almost all power grids. It results in the sinus wave of the alternating current become non-symmetrical (non-sinusoidal) and has negative impact on all devices using transformers. It causes their cores to become magnetized, what increases their noise, diminishes the efficiency of power supplies and lower sound quality as a result of those. The DC blocker allows to eliminate this phenomenon effectively, without causing any compression or any other negative influence on the sound
