But what is this mysterious silver box all about, and how does it improve the sound if no audio signal passes through it? Here’s how: The IsoTek EVO3 Syncro Uni is a mains filter, or, to be more precise, a DC blocker. A clean alternating current (AC) is subject to numerous impurities on its way from the power supplier to the wall socket. One of the culprits? Direct current (DC). So what’s the problem? If the alternating current can ideally be described as a sine wave, contamination by the direct current can result in a potential shift. This, in turn, can have a negative effect on transformers as well as the capacitors of your power supply. The resulting suboptimal power supply can affect the final signal in the form of lower dynamics and dull sound. However, the IsoTek EVO3 Syncro Uni is looped in front of a power strip and uses an innovative electronic circuit to keep the sound-polluting direct current components away, rebalancing the alternating current sinusoidal curve as well as reducing annoying power supply hum.
If your power strip does not have a DC filter, the Syncro Uni is ideal for bringing more vitality, clarity, and dynamics back into the sound of your system so that the next time you hear “Thunderstruck”, Angus’ guitar sounds exactly as it should.
