DOEPKE DFS 2F Audio

A residual current circuit breaker is an electromechanical device for the protection of persons. It can protect against indirect electrical contact if the accessible metal parts of the installation are connected to a suitable earth. And, when its rated residual current is less than or equal to 30 mA, it is also used as a means of supplementary protection against direct electrical contacts, in the event of failure of the other measures for protection against electric shock.

Since this device is a protective device, it is necessary to ensure that it functions correctly and that it is correctly selected and installed.

From the outside, it may look the same as your current residual current circuit breaker by 99%, but the internal parts are completely different wherever you look.

The first (very important) difference is the absence of those dreaded inductors, they have been replaced by a straight rod, which of course has negligible inductance, as it doesn't even have a single turn! Here, an important step has been taken to ensure an unimpeded flow of peak currents, which strongly promotes dynamics in your system.

The second: the contacts. No effort has been spared to ensure the lowest possible resistance and noise. The best materials and large contacts with unusually high contact pressure contribute to the ultimate goal of negligible resistance and noise.

Of course, safety has not been forgotten, in fact, it has been emphasised. The Doepke differential switch copes with non-sinusoidal waveforms admirably; waveforms like this occur today due to a large number of switch-mode power supplies (SMPS) everywhere around it, even current components that are not 50 Hz are no problem. Safety is guaranteed in all circumstances. Now and in the future.

The Doepke DFS 2F Audio is indeed the best of both worlds: it protects you and your loved ones from electric shock in all circumstances, while greatly restoring your audio/video experience to what it should have been from the beginning, without adding any artificial effects, just making sure your equipment gets the best basis for extracting the best audio and video quality by removing unwanted and network restricting components.
