PowerCell 12 UEF S

Power to transform.


The PowerCell 12 UEF S is wired with 10-gauge Silver Matrix wire with Graphene between each bank of Active Electromagnetic Cells. The remaining (2) UEF Black Duplexes in each bank are daisy chained with the same 12-gauge Silver Matrix wires as found in our standard PowerCell 12 UEF. The inclusion of heavier 10-gauge wire between the critical EM Cell to AC outlet junction allows the S version to deliver slightly more current on demand than is possible when thinner 12-gauge wire is used throughout and this translates into improved dynamics and sound quality for your system. Of course Graphene and UEF Tech are used throughout the PowerCell’s circuit and Active EM Cells to increase conductivity and overall performance. The S version takes a huge leap forward over the standard PowerCell 12 UEF thanks to an included High Current Level 3 Atmosphere power cord with a Swiss Made power supply for Active Shielding. Last but not least we fitted it with our highest performance UEF Black Duplex outlets with technology adapted from our award-winning UEF Black fuses.

What’s inside?

The PowerCell 12 UEF starts with a high carbon steel chassis treated with a UEF Coating that blocks EM and RFI interference and is designed to function as a superlative conduit for our new Ground Plane Technology. 

ULF Field Generator

Learn More

Developed exclusively for the PowerCell 12 UEF, the ULF (Ultra Low Frequency) Field Generator connects direct to the PowerCell 12’s (6) Active EM Cells through a process of inductive coupling between the ULF signal, ground and AC. It’s designed to clean your electric power by re-clocking the A/C with a rich, low-frequency harmonic that overrides noise and hash found in most common 50-60 cycle A/C.

EM Cells

Learn More

The New PowerCell 12 UEF AC Line Conditioner is the culmination of 10 years of research into electromagnetic cell design starting with the first EM Cell prototype in 2007. EM Cells act to condition alternating current through the inductive coupling of differential EM fields and AC for an AC power conditioner that is entirely non-current limiting. The electromagnetic cells in your PowerCell 12 UEF SE operate in ways similar to a hydrogen cell, hence the name PowerCell, however, instead of a chemical reaction, an inductive coupling takes place between the plates. The effect of this reaction drastically reduces reactive capacitance in the AC signal transfer, preventing phase anomalies with a total absence of noise on the AC line.

The (6) Electromagnetic Cells provide two stages of filtration: (1) large 640 cm² “flat” cell covering all 12 outlets, and (5) 819 cm² ”folded” cells shielded and housed in carbon fiber cylinders. Four of the folded cells cover the outlets’ positive and negative poles or (2) cells each per three duplexes. The fifth folded cell covers the current’s ground plane system-wide. This new configuration makes it possible for the PowerCell 12 UEF SE to provide twice the filtration area of the outgoing PowerCell 10 UEF.

Altering the shape of the EM cells changes their inductance properties and thus their sound quality. Flat EM cells subjectively increase sound-staging air and liquidity while folded EM cells enhance detail, dynamics, and focus. Using both types of cells in unison gives your system the best attributes of both folded and flat EM Cells.

Further, the EM Cells now contain Graphene, a new highly conductive wonder material that consists of a single layer of pure carbon only a single atom thick. One of the many reasons that Graphene is so exciting is that it is almost a superconductor at room temperature. Superconductors are materials that can conduct electricity with almost no resistance when cooled to extremely low temperatures ranging from near absolute zero (-459.67°F or -273.15°C) to the temperature of liquid nitrogen (-140.8°F or -96°C). What makes Graphene so remarkable is that it can do this at room temperature.

Black UEF Duplexes

Learn More
Plug up to twelve of your components into six of our new, top-of-the-line Black UEF Duplex outlets (retail $250 each). These six duplexes are connected to their respective EM cells with our Teflon coated, 10 and 12-gauge, Silver Matrix multi-stranded conductors. To further improve the quality of your analog and digital component’s performance, the six duplexes are divided into two banks, eliminating signal interference caused by AC power, giving the ultimate level of discrete isolation.

Silver Ground Strap

Learn More

The highly conductive 62 cm² 99.995% pure silver Ground Strap is UEF treated and features Graphene for ground filtration borrowed from our award-winning SR Ground Block. In fact this Pure Silver Ground Strap is attached to each of the (6) SR Black AC outlet to Star Ground your entire system when components are plugged into the PowerCell 12 UEF. Star Grounding with UEF Filtration reduces series inductance in the ground path for a noticeable improvement in sound quality over traditional grounding options.

The term “ground” refers to a connection to the Earth which acts as a reservoir charge. The highly conductive Pure Silver Ground Strap provides a conductive path for ground separate from the normal current-carrying path of your components which under certain conditions can add up to 10 dB of noise. The ground path with the least resistance is the best path to Earth and there is no better ground path than the PowerCell 12 UEF’s Pure Silver Ground Strap.

PowerCell 12 UEF S Schuko

Take your conditioning International


Soundstage! Ultra “Product of the Year”

The PowerCell 12 UEF SE just might represent the state of the art of power conditioning. It is a testament to the long way Synergistic Research has come since Ted Denney felt that he had yet to discover a power-conditioning technology worth taking further. But in addition to performance, the PowerCell 12 UEF SE offers high value. You won’t find many, if any, competing models that offer 12 outlets, a topnotch power cord, and an AC wall outlet, all for $5995. And while I’m generally not keen on visual gimcracks, that big window in the PowerCell 12 UEF SE’s top plate presents a display that impresses audiophiles and non-audiophiles alike.

“Synergistic Research has another winner with the PowerCell 12 UEF SE. I was pleasantly surprised if not astonished at the improvement in sound quality over my past benchmark—the excellent PowerCell 10 UEF. Unlike other power conditioners that I have auditioned, the PowerCell 12 UEF SE never feels like it throttles or diminishes the music. Yes, we have superior levels of isolation which results in an impressive reduction in the noise floor, but all the excitement and dynamic contrast of the recording as originally intended is still laid out for all to hear. This one will not be leaving my listening room.”
