There are a number of devices already on the market that are commonly referred to as ‘mains regenerators’. Typically, these attempt to reconstitute an ‘ideal’ mains sine wave by matching the incoming mains supply to a 50 or 60Hz ‘template’. The effectiveness of these regeneration systems is at least partially dependent upon the level of distortion of the incoming supply.

IsoTek’s Genesis is distinctly different. Unlike existing mains regenerators, it builds a completely new sine wave within two identical, independent generation cells. An extremely low distortion, synchronous sine wave generator creates a fully optimised signal inside each cell, which is amplified by a 300W generation engine running in Class A/B and fed to a high-quality output transformer with copper foil between the primary and secondary output, thus preventing distortion and noise passing through the unit. When both cells are combined, the result is 600W of continuous, newly generated power.

A critical part of the process is IsoTek’s unique synchronous sine wave system, which replicates the frequency with zero variation so as not to create destructive harmonic distortions (beat frequencies) between the incoming mains supply and the generated electricity. In addition to eliminating distortion and producing an ultra-stable sine wave, the Genesis also controls mains voltage, ensuring the output voltage is maintained at 230V +/- 2%. By way of comparison, the European standard is 230V +/- 10%.

The end result is an extremely precise and consistent 230V/50Hz (115V/60Hz) mains sine wave with vanishingly low levels of distortion, independent of the input quality of the power line. Whatever the level of distortion of the incoming mains supply, the EVO3 Genesis delivers exceptionally low THD (Total Harmonic Distortion) of between 0.05% and 0.17% with typical loads, remaining well below 0.3% with even the most complex loads.

The EVO3 Genesis was born from a desire to make a more effective mains generative component, as Keith Martin, IsoTek’s founder and managing director, explains: “We looked at existing regeneration systems and thought ‘we can build something better’; six years of extensive R&D later and this is the result. We call the Genesis a dual-cell mains sine wave generator, rather than a regenerator, to emphasise the unique way in which it operates – using two 300W generation engines to create a fully optimised mains sine wave from scratch. No other device delivers such ultra-low levels of distortion with such unerring consistency, and the resultant uplift in sound quality is remarkable: clearer, smoother and better defined, more open, dynamic and engaging.”

The EVO3 Genesis is optimised for front-end components – source components and preamplifiers – because they are Class A devices and use almost constant current regardless of the music being reproduced.

Four high-quality outlets are provided, each one fully isolated; no two outputs are connected together, thus eliminating differential mains noise created by cross-contamination between the connected audio components. At the front of the unit, a bright, clear OLED display shows input/output voltage, input/output THD, power consumption of the connected audio equipment and the power status of the generation engines.
