Design and features

The Esotek Gemini V5 is a compact cleaning and power distribution bar measuring just 270mm long, 80mm wide and 50mm high. It has two individual outputs, these refer to the central internal PCB. Most power filters of this style link output plugs, each connected in series. This is an error of judgment as differential mode noise, created by the connected load (your audio components) will be cross-contaminated between the output jacks. The electrical architecture and design of the Esotek Gemini V5 power strip prevents this and is therefore superior.

The Esotek Gemini V5 features a unique delta filter topology, ten times higher than the recommended standard, which delivers over 20dB power cleanup at 1kHz (reference 600 ohms), then boosted to 42dB at 10kHz. Most leading experts agree that 10 kHz is where radio frequency interference (RFI) starts to influence performance. This is also related to the amplifiers ability to reject power supply noise. This electrical engineering ensures class leading power cleaning performance for both common mode (RFI) and differential mode mains noise. The Printed Circuit Board (PCB) is also twice the standard copper load and is silver plated.

This unique circuit provides clean power to its two output sockets, each independently isolated to prevent cross contamination from differential mode mains noise. This is combined with IsoTek's KERP© (Kirchhoff Equal Resistance Path) to ensure equal resistance and power delivery to all outlets. The internal wiring is of the highest standard, a unique 2mm² design with 6N pure oxygen free copper conductive strands, each silver plated, offering low resistance and high current capacity. An aerospace grade fluorinated ethylene propylene (FEP) dielectric, with very low dielectric strength, is used to protect the conductors and provide an ideal conductor contact dielectric for the internal power supply system.

Eliminate network noise

Mains noise in differential mode is created by all electrical appliances, in fact, everything that has a power supply. This includes your microwave oven, your TV, and your computer, as well as any hi-fi components you own.

Common mode network noise is often referred to as Radio Frequency Interference RFI – transmitted frequencies that surround us but cannot be seen. For example, imagine how much data smartphones and tablets transmit. Cheap power cables act as antennas for these unwanted frequencies.

Sine wave correction

From the point of view of high quality audio, the electrical network needs two factors; a good 50 or 60 Hz sine wave supplied from a very low impedance source, with no RF noise. The low impedance generates a nearly constant voltage regardless of how much power is being used in the surrounding area. In reality, we can normally expect a fluctuation of around 5%. The very low impedance of the network, which is well below 1 ohm at 50 or 60 Hz, is not maintained when approaching radio frequencies (>50 ohms at >100 kHz) and acts as an antenna that invites noise. RF radio frequency noise.

Independent sockets

IsoTek products have power plugs that are completely independent of each other; no two outlets are directly connected. This is a critical point to limit or eliminate cross-contamination of differential mode mains noise.

Each plug connects directly to the printed circuit board and is serviced by IsoTek's exclusive power cleaning technologies.

Audiophile grade components

Every IsoTek product uses the highest quality electrical components, many custom made using the highest quality metals and materials that are designed specifically for their purpose. The quality doesn't stop at the parts, it also extends to the PCB designs, which maintain high amperage levels and extraordinarily low resistance levels, using up to eight times the general standard of copper before pure silver plating.

The internal wiring also uses high-purity copper combined with silver plating with either IsoTek's Fluorinated Ethylene Propylene (FEP) dielectric or Virtual Air (VDA) dielectric, where an FEP tube is wrapped around the conductor before it is An extruded FEP dielectric protects this construction providing performance and the ultimate high performance, low resistance internal power delivery system.

Surge protection

Power surges or spikes in the power supply are generally very bad for any electrical device, especially a high quality audio playback system. Power surges occur when there is an increase in electrical load at some point on power lines. This causes an increase in electrical potential energy, which can increase the current flowing to the wall outlet. This, in turn, can damage your sensitive audio system.

The IsoTek protection system uses a series of VDRs that offer a cascading level of protection, in some cases exceeding 100,000 A. These intervene quickly and sequentially depending on the severity of the surge or spike encountered. The protection circuit architecture extends dramatically and almost instantly when required.

The protection circuit has two main functions, one to preserve itself and the second to intervene gradually as any problem increases, with the ability to act very quickly should an extreme condition occur. The protection circuits also protect the filters and the filters help the protection in the initial stage. Unlike many protective devices, these help improve sound quality and provide protection. Studies suggest that this problem is not subtle and is common. The disturbing challenge is the 1,000 V to 6,000 V range. Most protection systems are likely to do very little good and likely lead to sound degradation.

Technical papers state that Kirchhoff's circuit laws are two equalities dealing with current and potential difference (commonly known as voltage) in the lumped element model of electrical circuits. They were first described in 1845 by the German physicist Gustav Kirchhoff. This generalized the work of Georg Ohm and preceded the work of James Clerk Maxwell. Widely used in electrical engineering, they are also called Kirchhoff's rules or simply Kirchhoff's laws. These laws can be applied in time and frequency domains and form the basis for network analysis.

The guiding principles of the IsoTek circuits are governed by the two current Kirchhoff laws, a simple analogy would be that for every liter of water that is put into a water distribution system we would expect to obtain the same.

To put it another way, Kirchhoff and Gauss described how seemingly impossible problems could be solved by the concept of the city. If the traffic flows in a circular orbital highway around the city, there is no effect on the city. However, if traffic enters the city, then there will be an effect on the city, and no matter how many cars enter, they will eventually have to leave. The structure of that town will have a positive or negative effect on that migration. In electronics this is also true. You have to fully respect the path of the signal since, whether you like it or not, in the end everything will be to a greater or lesser degree in the path of the signal.

Copper multiple conductor MULTI CU 6N OFC AG

As you would expect, the internal wiring of any IsoTek product is of the highest standard, pure high purity Oxygen Free Copper Cu 6N OFC (Oxygen Free Copper - 99.9999%) silver plated conductive strands offering low resistance and high amperage. An FEP dielectric is used to protect the conductors as well as providing the best internal power supply system.

IsoTek's internal wiring synergizes with the IsoTek range of power cables. A critical but overlooked area is maintaining commonalities of design and materials throughout an audio wiring loom, whether it is the cables that carry signals or your network of power cables.

Continuous absolute power

IsoTek offers absolute power, unrestricted power delivery within what the power company can supply and regulations allow. In general, for power amplifiers or high power electronics, IsoTek provides an output that offers extremely low impedance and low DCR, which completely eliminates (within power filtering concepts) any possibility of current restriction and improves dynamic range, the impedance of the chain back to the power plant is much larger. When the power is polluted, the dynamic range is reduced.

It is impossible to get more than 100% from the power grid. The very principle of AC power is that it does not store energy in the transmission system. Therefore, it is impossible to store energy in an alternating current system by the same principles by which it works. There can be no so-called energy reserve, therefore an energy reserve within an alternating current circuit in the true sense of the word does not and cannot exist.

The power reserve would require the voltage to go up, as ohms law insists it must, saying that a circuit doesn't sink, it's not a power reserve. The AC waveform goes between the maximum and minimum points at 50 Hz in 10 ms, then oscillates to the maximum negative value. At 20 ms a complete cycle is achieved. Therefore, in fact, the average values ​​of an alternating current waveform are zero. Only as a power wave can it be positive, this is due to the law of negatives squared. It looks like a bulging sine wave where the value of 45 degrees is 0.5 and not 0.7071 from a trigonometric table. If this were just a voltage ripple it would have a long term value of zero! As far as energy storage is concerned, zero is the value of stored energy.

Direct current resistance (DCR) will cause sinking. In other words, a system must be developed that does not limit the power plant's power reserve, which means that a circuit must have extremely low resistance while maintaining a sufficiently high inductance. When done correctly and in perfect balance, the inductance is practically zero at 50/60 Hz and the DC resistance (DCR) is also very close to zero. Therefore, an ideal filter circuit should maintain a DC resistance of zero ohms (or very close to it) and a considerable AC resistance to noise above 50/60 Hz. Despite statements to the contrary, here this is precisely where correctly specified materials are most important.

Most alternating current circuits are reactive: they produce a reaction from the power consumed or from the circuit itself; simply put, they are not pure resistors and behave like a capacitance and a resistance or an inductance and a resistance. In an ideal world, the only allowable impediment is resistance, and ideally this should be extremely low. A dilemma, do you want high transient power or do you want intense filtration? Surprisingly, you can have both, but one must have the highest quality components, that are specifically designed for a purpose with totally correct architecture. This is extremely complex and has resulted in the design of specialized parts;
