{"title":"DC Cables","description":"\u003cp\u003eA DC cable connects an external linear or plug-in power supply to the device it powers – such as a streamer, network switch or DAC.\u003c\/p\u003e\n\n\u003ch2\u003eWhy a good DC cable?\u003c\/h2\u003e\n\u003cp\u003eIf you power small digital devices with a high-quality linear power supply, you want that clean DC voltage to reach the device with as little loss and interference as possible. That's exactly the job of the DC cable: solid conductors, good shielding and a firmly seated, correctly sized barrel connector. That way the calm voltage of the power supply arrives where it's supposed to work – without new trouble from a wobbly or mismatched plug.\u003c\/p\u003e\n\n\u003ch2\u003eWhat matters\u003c\/h2\u003e\n\u003cp\u003eAbsolutely critical are the correct plug size and the right polarity – there's no room for guesswork here, a wrongly poled or wrongly sized cable can damage devices. In addition there's sufficient cross-section and good shielding. At HD Zürisee in Wädenswil we check the voltage, polarity and plug dimensions of your power supply and device before anything is plugged together.

The more generous the cross-section, the less voltage is lost on the way and the more stable the supply stays when the device briefly draws more. At 2 × 2 mm², that's ample for a DC cable; the brown fabric sleeve keeps everything flexible and tidy.\u003c\/p\u003e\u003ch2\u003eWhat you get\u003c\/h2\u003e\u003cp\u003eThe right connector combination – and with it the part where all the effort otherwise gets stuck. A high-quality linear power supply connected via the bundled lead is like a good wine in a toothbrush cup.

If yours takes 2.5 mm on both ends, Version 1 is the right one. The difference is tiny, but it decides whether the connector holds or wobbles.

Alternatively, measure the inner pin of the existing socket. If you're unsure, tell us your device and power supply – we'll tell you which version fits.\u003c\/p\u003e\u003ch3\u003eWhat happens if the connector doesn't fit exactly?\u003c\/h3\u003e\u003cp\u003eAn inner diameter that's too large sits loose, contact becomes unreliable and can drop out in operation. One that's too small won't fit at all.
