Worlds first audio/video grade differential switch
Nowadays, audio grade fuse holders are quite common in the meter cupboard, however, the bottleneck still exists, namely your "standard" differential switch. Doepke introduces a version specifically designed for the most demanding audio/video enthusiasts who only settle for the very best. This differential switch has been designed by an employee of Doepke, who is a passionate audiophile too. In his spare time, he's worked for many years on this product, until it fully met his own standards: the highest possible audio- and video quality. In addition, this differential switch offers enhanced safety: even with deviating wave forms (as often introduced by switch mode power supplies) it switches off reliably. Differential switches are obligatory in all home electricity systems. The main goal is to protect against electrocution. A differential switch compares the in- and outgoing currents through live and neutral, the sum of these has to be zero. The only disturbance possible of this balance is, when a certain current flows to earth. If this currebt flows through the body of a human being, this can be life threatening. This is where the differential switch kicks in and disconnects the circuit from the mains if this current is over 30 mA. Audio/video enthusiasts sometimes tend to bypass their differential switch, this is however illegal and highly unsafe. Insurance companies will not pay if they notice this has been done. We strongly discourage doing so. The best thing is, you don't need to anymore with the introduction of the Doepke DFS differential switch.

DFS F Audio – for maximum listening enjoyment
Easy on the eyes and ears: The new DFS F Audio was designed  specifically for use in circuits comprising premium, sensitive sound systems.
The residual current circuit-breaker won’t affect the listening experience of those with even the most sensitive of ears.
And there’s no need to hide the DFS Audio away – with its classy vinyl black exterior and white lettering, it fits right in with the premium equipment it protects.

This type F residual current circuit-breaker offers reliable protection against dangerous residual currents even with mixed frequency fractions in the event of a fault – and all without losing sound quality.  
The low-impedance design of the DFS Audio ensures an unhindered listening experience.
It has solid silver-plated connection  terminals and gold-plated terminal screws.
Solid silver-plated internal conductors made of high-purity, low-oxygen copper ensure an unrestricted flow of current and the special design of the summation current transformer prevents undesired inductive fractions.

The DFS F Audio comes in a two-pole and four-pole version with a rated residual current of 30 mA and for rated currents of up to 63 A.
It protects personal audio equipment but is also the ideal choice for professional applications, such as for sound systems in theatres, concert halls and cinemas.  

-silver-plated connection terminals  and solid silver-plated conductors
-high-purity, low-oxygen copper and large switching contacts
-extremely low-impedance design makes  inductive fractions ineffective
-residual current protection without any loss of sound
