EVO3 Sigmas

One of the most cost-effective upgrades you can buy for any high-quality audio system, Sigmas is a multi-award-winning six-way mains conditioner featuring two high-current outlets that utilizes a lighter version of the Titan’s Direct-Coupled© circuit to provide high current low impedance power for amplifiers, subwoofers, or active loudspeakers. The four remaining output sockets are medium-current for source components. Each outlet of Sigmas has its own dedicated power cleaning network; thus, six power cleaners in one box! Sigmas represents an extremely cost-effective way to fully upgrade a complete high-end audio system.

 

Features
  • Suitable for all audio or AV systems
  • RFI reduction 75dB
  • 6 optimised power cleaning circuits remove Common and Differential Mode mains noise
  • 4 independent outlets for source components (10A max each)
  • 2 independent high current outlets for power amps, subwoofers, active speakers etc.. (16A max each)
  • 108,000A instantaneous protection
  • Fully star-earthed network
  • Solid core Ohno Continuous Cast copper silver-plated internal wiring with FEP virtual air dielectric.
  • Supplied with IsoTek’s award winning EVO3 Premier power cable
  • UK, EU, US, AU & CH outlets available

Design

The EVO3 Sigmas is an innovative component with a power cleaning and distribution system measuring 445mm in width, 305mm deep and 90mm high. It is a significant step up from the Aquarius. Sigmas is six power cleaners in one box, six independent outlets, each one with its own dedicated power cleaning network. These dramatically reduce both Differential Mode and Common Mode noise. Cross contamination of connected components is also kept to a minimum due to the multiple power cleaning stages for each output socket. Most power filters 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 Sigmas is dramatically superior.

There are two high current low impedance outlets, rated at 16A, delivering 3,680W at 230V or 1,840W at 115V. These are suitable for power amplifiers, active loudspeakers or sub woofers and feature a light version of the Titan’s Direct Coupled© circuit. The four remaining medium current outputs rated at 10A are designed for source components. These feature IsoTek’s unique Adaptive Gating © technology that autosenses the connected load, thus giving the ideal optimal clean power based upon power draw. The power cleaning network is more sophisticated than that of Aquarius.

KERP © (Kirchhoff’s Equal Resistance Path) ensures equal resistance and equal power delivery to all outlets. The internal wiring is of the highest standard; ultra-pure Ohno Continuous Cast copper solid core conductor strands with silver-plating offering low resistance and high amperage. A Fluorinated Ethylene Propylene (FEP) helix is wound around the conductor before an extruded FEP dielectric protects the conductor and creates a Virtual Dielectric of Air dielectric (FDA). This construction gives unrivalled performance and gives the ultimate low resistance, high performance internal power delivery system. Furthermore, 108,000A of instantaneous protection is provided, safeguarding valuable equipment via IsoTek’s unique sequential and repeatable protection system.

Sigmas is high quality design yet highly functional and an excellent upgrade for a complete high-end audio system improving sound stage, three-dimensional imaging, bass articulation, control and a sense of extended frequency range and openness. IsoTek’s award winning Premier power cable is also included.

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.
