Removes Mains Noise

Differential Mode mains noise is created by all electrical appliances – everything with a power supply, in fact. This includes your microwave oven, your television and your computer, as well as every hi-fi component you own.

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

From a high quality audio point of view, mains electricity needs two factors; a nice 50 or 60Hz sine wave supplied from a very low impedance source, without radio frequency noise. The low impedance makes for a near constant voltage regardless of how much power is used in the surrounding area. In reality we can typically expect around 5% fluctuation. The very low impedance of the mains, which is way below 1 ohm at 50 or 60Hz is not maintained when approaching radio frequencies (> 50 ohms > 100 kHz) and acts as an aerial (antenna) inviting RF noise.

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.

Multiple Filter System

Many IsoTek products are not just a single power cleaning system but are multiple power cleaners in one convenient chassis. The advantage being that each component in your audio system has own dedicated clean power delivery system. Furthermore, Differential Mode noise, created as electrical devices draw power, is kept to a minimum and the possibility of electrical noise cross contamination between outlet sockets is eliminated.

Many power cleaning systems simply place a standard filter design in a box with all outlet sockets joined together in series one after the other, thus connected equipment cross contaminates and the purpose of the product is lost.

Independent sockets

IsoTek products feature outlet sockets that are totally independent from each other; no two outlet sockets being directly connected. This is a critical point for limiting or eliminating the cross contamination of Differential Mode mains noise.

Each socket connects directly back to the PCB and is serviced by IsoTek’s unique power cleaning technologies.

High Grade Components

Every IsoTek product uses the finest grade electrical components, many custom made, using the highest quality metals and materials which are specifically designed for purpose. Quality doesn’t stop at parts but also extends into the PCB designs, which maintain high levels of amperage and extraordinarily low levels of resistance, using up to eight times the general standard of copper prior to pure silver plating.

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

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

DESIGN

EVO3 Mini Mira features two power cleaning circuits, one which is dedicated for projectors, LCD, LED, OLED, QLED or older CRT screens (basically with all types of TVs), the second which can be used for all other electronics from set top boxes to DVD or content storage devices. It is a compact box measuring 170mm in length and 130mm in width and 65mm high, making it easy to position either behind cabinets or ceiling mounted next or close to projectors.

The EVO3 Mini Mira ensures class-leading power cleaning of both Common Mode and Differential Mode mains noise. Two independent circuits prevent cross-contamination of connected equipment. 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.

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.
