DESIGN
The EVO3 Sirius is a compact yet elegant power cleaning and distribution bar measuring 480mm in length, 88mm wide and just 50mm high. It features 6 independent outlets each one referencing back to the central PCB to dramatically reduce Differential Mode cross contamination of connected components. Most power filters of this style join output sockets together, running each in series. This is an error as Differential Mode Noise created by your connected electronics will cross contaminate from one output socket to the next. The electrical architecture and design of Sirius is superior.
The EVO3 Sirius has a unique delta filter topology ensuring class-leading power cleaning of both Common Mode and Differential Mode mains noise. This is combined with IsoTek’s unique Inductive Resonance Gate © which further optimizes the isolation between each of the six output sockets. Clean power is then delivered to all six output sockets – each one independently isolated to prevent cross-contamination of mains noise. KERP © (Kirchoff’s Equal Resistance Path) ensures equal resistance and equal power delivery to all outlets. The internal wiring is of the highest standard, pure 6n oxygen free copper conductor strands with silver-plating offer low resistance and high amperage. A PTFE dielectric is used to protect the conductors as well as giving the ultimate internal power delivering system. Furthermore, 22,500A of instantaneous protection is provided, safeguarding valuable equipment via IsoTek’s unique sequential and repeatable protection system.
Housed in an extruded aluminium chassis, Sirius is a solid hard wearing power bar that can easily be wall mounted behind audio systems or placed discretely behind audio racks.
The internal wiring of IsoTek products synergizes with the range of IsoTek power cables. One critical but overlooked area is maintaining commonality of design and material properties though an audio wiring loom, be it signal carrying cables or your power cable network.
REMOVES MAINS NOISE
Common Mode mains noise is often referred to as RFI – transmitted frequencies that surround us but we cannot see. For example, imagine how much data is transmitted by smartphones and tablets; cheap power cables act as aerials (antennas) for these unwanted frequencies.
SINE WAVE CORRECTION
IsoTek’s power cleaning circuits are designed to reduce impedance whilst remaining safe as well as correcting well into the audio frequency bands. This is not only a judgment from sound electrical engineering, but it also follows the codes of electrical safety, which are independently assessed.
INDEPENDENT SOCKETS
Each socket connects directly back to the PCB and is serviced by IsoTek’s unique power cleaning technologies.
HIGH GRADE COMPONENTS
Internal wiring also uses high purity coppers combined with silver plating, with either Fluorinated Ethylene Propylene (FEP) dielectric or IsoTek’s Virtual Dielectric of Air (VDA), where a FEP tube is wound around the conductor before an extruded FEP dielectric protects this construction giving unrivalled performance and the ultimate low resistance, high performance internal power delivery system.
SURGE PROTECTION
The IsoTek protection system uses an array of VDRs which offer a cascading level of protection, in some cases over 100,000A. These step in fast and sequentially dependent upon the severity of the encountered power surge or spike. The architecture of the protection circuit extends dramatically and almost instantly when required.
The protection circuit has two primary functions, one to preserve itself and the second to step in gradually as any problem increases, with the ability to act very fast should an extreme condition occur. The protection circuits also protect the filters and the filters assist the protection in the initial stage. Unlike many protection devices these assist sound quality as well as providing protection. Studies suggest this problem is not subtle and is frequent. The disturbing challenge is the 1,000 to 6,000V range. It is likely most protection systems do very little good and probably cause sound degradation.
K.E.R.P.
The guiding principles for IsoTek circuits are driven by Kirchhoff’s two current laws, a simple analogy would be that for every litre of water placed into a water distribution system we would expect to get the same out.
To put it another way, Kirchhoff and Gauss described how seemingly impossible problems could be resolved by the concept of a town. If traffic flows on a circular orbital road around the town there is no effect on the town. However, if traffic enters the town, then there will be an effect on the town, and however many cars that enter eventually have to leave. The structure of that town will have either a positive or negative effect on that migration. In electronics this is also true. We must totally respect the signal path as, whether one wishes it or not, ultimately everything will be in the signal path to a greater or lesser degree.
MULTI 6N OFC AG
As one would expect, the internal wiring of any IsoTek product is of the highest standard, pure 6n OFC (Oxygen Free Copper – 99.9999%) conductor strands with silver-plating offer low resistance and high amperage. An FEP dielectric is used to protect the conductors as well as giving the ultimate internal power delivery system.
IsoTek’s internal wiring synergizes with the range of IsoTek power cables. One critical but overlooked area is maintaining commonality of design and material properties though an audio wiring loom, be it signal carrying cables or your power cable network.
CONTINUOUS ABSOLUTE POWER
It is impossible to get more than 100% out of the mains supply. The very principle of AC power is that it doesn’t store energy in the transmission system. It is therefore impossible to store energy in an AC system by the very principles by which it works. There can be no so-called power reserve, thus a power reserve within an AC circuit in the truest sense of the word does not and cannot exist.
Power reserve would require the voltage to increase as ohms law insists it must, saying a circuit doesn’t sag isn’t a reserve of power. The AC waveform goes between maximum and minimum points at 50 Hz in 10 mS, it then swings to the maximum negative value. At 20 mS a full cycle is achieved. Therefore, in fact the average values of an AC waveform is zero. Only as a power wave can it be positive, this is due to the law of squared negatives. It looks like a ballooned sine wave where the value of 45 degrees is 0.5 not 0.7071 from a trigonometric table. Were this only a voltage wave 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 sag. To put it in other words, a system has to be developed which does not limit the power reserve of the power station, meaning a circuit needs to have extremely low resistance whilst maintaining sufficiently high inductance. When done correctly and in perfect balance the inductance is virtually zero at 50/60 Hz and the Direct Current resistance (DCR) is also very close to zero. Therefore, an ideal filter circuit must maintain zero Ohms resistance DC (or very close) and considerable AC resistance to noise above 50/60 Hz. Despite statements to the contrary, this is precisely where correctly specified materials matter most. Whilst some might consider these ‘exotic’ they represent a critical and important part of the function and appropriate to use. Remarkably IsoTek filter designs can maintain very low resistance at 50/60Hz but have very high amounts of noise cancellation above that frequency.
Most AC circuits are reactive – produce a reaction either from the power drawn or the circuit itself, put simply they are not pure resistors and behave like a capacitance and resistance or an inductance and resistance. In an ideal world the only allowable impediment is resistance and ideally this needs to be extremely low. A dilemma, do you want high transient power, or do you want heavy filtration – amazingly you can have both, but one must have components of the very highest quality, which are designed specifically for purpose with totally correct architecture. This is extremely complex and has resulted in the design of specialist parts; these do not exist outside the world of specialist power engineering and are unique to IsoTek designs.
