Isotek :: syncro mains cable

In simple terms, Syncro is IsoTek’s most advanced mains cable – but it’s also so much more. The cable incorporates innovative electronics, housed in an anti-resonant aluminium case positioned part way down its length.

Syncro is not a mains conditioner or filter in the accepted sense. It can be used on its own to power a single hi-fi component, and will bring significant improvements if used in this way. However, it is primarily designed as a ‘pre-filter’ device – for best results, plug the Syncro into a wall socket and use it to power an IsoTek (or other) mains conditioning unit.
Thus, Syncro takes the mains electricity supply and realigns its waveform symmetrically around ground potential, prior to filtration of contaminants (RFI/EMI etc.) by the conditioning unit, which then feeds each hi-fi component – thus improving the performance of every link in the audio chain.

Syncro also removes a problem which is sometimes referred to as ‘DC on the mains’. In terms of audio equipment, it is often signified by a buzzing sound emitted by a transformer in a power amplifier. Of course, this buzz is extremely distracting but in addition, the mechanical vibration within the power transformer, created by core saturation, results in microphony in the internal components, leading to further degradation of sound quality. Most of the DC-related issues suffered by audio systems are brought into being by the electrical devices we own, directly ‘rectifying’ the mains from AC to DC (where a diode is used in series to allow either the positive or negative cycle of the mains sine wave to pass). The use of switch-mode power supplies exacerbates the problem, introducing measurable mains distortion. These devices create a lack of symmetry in the mains sine wave where it is displaced from the zero voltage line, leading to the aforementioned hum that’s often noticeable from power amplifiers, as the DC voltage saturates the core of the transformers with DC current. This, in turn, generates unwanted mechanical vibration, resulting in audible noise and microphony, and increased power consumption and heat.

Syncro’s synchronising effect results in greater bass depth, improved timing, a reduction in the noise floor and a more palpable sound overall. Furthermore, these improvements don’t come at the expense of dynamic ability; in fact, in some cases dynamics are considerably improved. This can be explained by the fact that at zero volume, many power amplifiers consume less power in idle. The Syncro helps the amplifier to consume less electricity, freeing up power for dynamic transients. A simple analogy is a car that is free running, as opposed to having the brakes slightly engaged.
