The Isotek EVO3 Syncro Active DC Blocking Cable is a DC-blocking power cable<\/strong> for audio equipment. Its electronics rebalance the mains sine wave to help reduce or silence transformer hum associated with a DC component in the mains supply. It can supply power to one component or be connected before an IsoTek power cleaner.<\/p>\n

When is it useful?<\/h2>\n

If a transformer in your equipment hums, a DC component in the mains supply is one possible cause. The Syncro is designed to address that cause. When deciding where to use the cable, start with the component that is humming and consider whether the hum could be related to its power supply.<\/p>\n

The cable can also be connected before an IsoTek power cleaner. In that arrangement, its DC-blocking function acts at the start of the power chain, before power reaches the cleaner. This option may suit a stereo or home cinema system that already uses an IsoTek power cleaner. How much the hum changes depends on its cause and on the particular system; a hum caused by something else may respond differently.<\/p>\n

Conductors and insulation<\/h2>\n

Inside the cable are three conductors<\/strong>, each with a cross-sectional area of 3 mm\u00b2. They are made from silver-plated Ohno continuous cast (OCC) copper. The square-profile strands run in a parallel arrangement, with a slight twist to the conductors.<\/p>\n

FEP insulation<\/strong> separates the conductors. FEP is chemically inert and has a low dielectric constant across a wide frequency range. Cotton filling inside the cable adds strength to the construction and helps reduce the microphonic effect. A PVC outer jacket gives the cable flexibility and mechanical strength. These construction details matter when routing a power cable through the space behind an equipment rack.<\/p>\n

Shielding, grounding and placement<\/h2>\n

Double shielding<\/strong> combines a Mylar film wrap with a grounded oxygen-free copper shield. Its purpose is to suppress radio-frequency interference. The cable also uses a fully star-earthed arrangement. Shielding and grounding address a different aspect of interference on the power line from the DC-blocking electronics; they are separate features of the same cable.<\/p>\n

The outer jacket has a diameter of 12.5 mm. Allow space for both the cable and its connector behind the equipment before pushing a component into place. This is especially useful when the power inlet sits close to the back of a shelf: planning the route helps you use the jacket\u2019s flexibility without pulling the connector tight.<\/p>\n

Choosing the connectors and version<\/h2>\n

Versions are offered with UK, EU, US and Australian mains plugs<\/strong>. At the equipment end, the available terminations are C7, C15, C19 and Neutrik. Choose the mains plug for the socket you use and the equipment connector for the inlet on the component or power cleaner. These are alternative cable configurations; the different connector names do not mean that every connector is fitted to one cable.<\/p>\n

The connector contacts are made from solid oxygen-free copper and plated with 24-karat gold. 10 A and 16 A versions<\/strong> are available. Check the rating of the actual cable variant and its terminations against the equipment inlet and current requirements. The model name alone does not identify which rated version is being offered.<\/p>\n

The standard cable length is 2.0 m, and custom lengths are available. When choosing a length, follow the intended route from the mains socket to the component or IsoTek power cleaner. Allow enough length to position the equipment conveniently and connect it without putting tension on the plugs or inlets.<\/p>\n

FAQ<\/h2>\n

Will this cable eliminate any transformer hum?<\/h3>\n

It is intended to reduce hum associated with a DC component in the mains supply. If the hum has another cause, the effect may differ. Choose the cable with the particular problem you want to address in mind.<\/p>\n

Where should I connect it if I use a power cleaner?<\/h3>\n

The Syncro can be connected before an IsoTek power cleaner, so its DC-blocking function acts before power reaches the cleaner. It can also supply a single component directly.<\/p>\n

Which equipment connector do I need?<\/h3>\n

Match the connector to the equipment\u2019s power inlet. C7, C15, C19 and Neutrik terminations are available. You also need a mains plug suited to your socket. These are choices to make when selecting the cable.<\/p>\n

How do I match a 10 A or 16 A version to my equipment inlet and connectors?<\/h3>\n

Check the type of power inlet and the equipment\u2019s current requirements. Then choose a matching connector and cable variant, confirming that the ratings of the offered termination and the specific cable version are suitable together.<\/p>\n

Can I use it in a stereo or home cinema system?<\/h3>\n

In either type of system, the cable can supply one component. If you use an IsoTek power cleaner, it can instead be connected before that cleaner. The required equipment-end termination depends on the inlet of the component or cleaner you choose.<\/p>\n

How should I choose the cable length?<\/h3>\n

Measure the route the cable will take, allowing room behind the equipment and avoiding tension at the connections. A custom length may be useful if the standard 2.0 m cable does not suit your layout.<\/p>\n","protected":false},"excerpt":{"rendered":"
