Supra LoRad MD01-16-EU - DC Blocker for Mains AC

Now, Supra Cables has taken yet another step to minimize the impact from malicious elements like DC (Direct Current) superimposed on the mains AC (Alternating Current) in most modern households and industries!
DC voltage derives from a number of electrical appliances and will cause an offset on to you alternating mains power. This offset is the result of electrical consumers that do not equally load the AC positive and negative phase. In the ideal mains power supply there should be no DC-offset at all. Refer to figure below

DC-offset on AC mains power (disproportionate illustrative figure)

This DC offset limits the power supply efficiency in most multimedia and hifi equipment and causes transformers to saturate (the iron core). It increases iron core heat build-up and may even cause transformers to sound with a humming noise. Finally it may prolong life of the equipment by means of lowering the heat dissapation inside the device. The sonic impact is in most cases quite dramatic and again it will scale off audible sounds that do not come from the recording. You will listen to music, movies but not to your mains power irragularities.

Again Supra Cables is leading the way by offering a very efficient DC-blocker stopping DC up to 3.6 Volt making it future proof also for next generations of electrical consumers giving DC-offset. It is very easy to add-on to your existing power feed. It does not require protective ground to operate, but we strongly recommend it for a number of other reasons. Your equipment will sound much better and all other Supra mains power devices in the LoRad product range will work ideally.

Again Supra Cables have launched a product that in comparison costs a fraction. We do not spend on bling, just bang for the buck. Our No-Nonsense strategy means that almost all hifi enthusiasts will afford a Supra Cable Product, making exactly the same benign impact.
It is rated 16 Ampere and consequently allows for 3,680 Watt of power. The connection cord is optional and we recommend our Supra Lorad Mains Cord rated for 16 Ampere for optimal operation. Note that the DC-blocker input connector is rated 16 Ampere.

N.B. The filter will not dampen any dynamics. When the sound is much cleaner and tighter after the filter is connected, sometimes listeners perceive the dynamics to be reduced. When there is a difference in music and sound reproduction that will remove parts not really belonging to the source, this is a quite common reaction. On the contrary, bringing down the noice from the equipment will undoubtedly increase dynamics and often substantially reduce the duration of e.g. a bass pulse. Now it will most likely be possible to hear every tone in the bass range, also from each tuned drum skin.

Important! When connecting and disconnecting the Supra DC-filter, follow this procedure. Pull the mains cord connector from the wall socket. Wait until all power LEDs have went out from the stand-by position. Now you can connect the existing mains power cord to the filter, connect the optional mains power cord to the filter and finally connect it to the wall socket. When disconnecting, always start with wall socket and wait until all connected devices LEDs go out. By doing this you make sure that no electrical charge remains in any of the devices or in the DC-blocker.
