I distributori Supra sono totalmente schermati da campi elettrici grazie al loro chassis in alluminio. Lo chassis conduttivo scarica l'interferenza a terra. Deve essere connesso ad una presa dotata di messa a terra con un cavo di rete anch'esso dotato di messa a terra, per permettere di lavorare in modo appropriato. Per un grado soddisfacente di schermatura ed immunità, il distributore di rete dovrebbe essere abbinato ed usato con cavi di rete schermati SUPRA LoRad.

Supra Mains Power Distribution Blocks allow for 2 up to 15 mains power sockets (EU) and a staggering 3.68 kW load still safe, noise-free and optionally surge protected. We provide for custom tailored filtering for anyone feeling that filters dampen transient respons in powerful power amplifiers and on stock standard variants are always socket one (1) un-filtered and remaining NIF-filtered. Our 8+ blocks provides as standard two un-filtered and remaining NIF-filtered. Our three-way SP-protection is a lavish protective circuitry in order to provide the maximum level of equipment safety. It will keep equipment safe whatever way the surge will enter, while competitors usually satisfy only Live to Zero surges.

Supra LoRad MD06-EU Switch

Supra mains distribution block consisting of EU sockets conforming to European Standards, with the exception of UK, Ireland, Belgium and Italy. Input connector is a 10 ampere male chassis connector according to the international standard IEC-320, i.e. the same for most electrical multimedia devices with detachable power cord including ground lead. It provides a 10 ampere fuse and a non-intrusive filtering (NIF).

Requires an optional input mains flex, see our section of mains power cord sets.

Include also a high current in-rush capable on/off switch allowing for turning the entire equipment on or off. Practical when zero power consumption is desired. Note that the switch does not protect from surge due to e.g. lightning. Refer to mains block models containing SP; surge protection. Note also that some devices may loose their memories, when kept without mains connection. They often require to be left in stand-by mode and not completely turned off. Refer to device owner's manual for further information.

Supra NIF Transient Filter

All models are equipped with Supra NIF (Non-Intrusive Filtering), an efficient high frequency (RFI) transient filter. It is designed and configured to efficiently suppress RFI interference, but not to dampen quick recharge demands from the connected devices power supplies. Supra NIF is developed by Ben Duncan Research in England.

All filtering and all protection need a mains wall socket with a ground terminal to operate. If your multimedia- and hifi equipment is of a certain standard, they will probably require ground connection themselves and use a IEC-320 socket for detachable mains power cords. If your equipment is such and you do not have ground terminal in your mains wall sockets, we recommend you to contact your landlord and/or an electrician to arrange for ground connection. Doing so, will undoubtedly both increase sound quality and the security for your equipment.


Supra LoRad shielded Mains Blocks in aluminium housing

The Supra mains blocks are shielded and radiated low levels of electricity generated fields thanks to their aluminium chassis connected to ground potential. The conductive chassis drains the internal interference down to ground and prevents also adjacent RFI and other malicious fields to enter the distribution block. It has to be connected to a grounded wall socket with a mains cable providing ground lead, in order to work properly. The mains cable connecting the mains block to the wall socket and the mains cables to each device should for maximum interference dampening/immunity also be shielded. We recommend our Supra LoRad Mains Flex as the best alternative to combine with our distribution block. If you are new to the field of mains power shielding and filtering, you will undoubtedly notice the difference.

The field leakage from the standard included mains flex to the vast majority of multimedia devices is clearly detectable with our Supra AC Detector;  Just touch the included mains power cable with the AC Detector white tip and you will hear a warning and see the tip rapidly flicker in red to indicate radiating fields from mains power. Now change to a Supra LoRad mains flex and touch the cable with the tip ... This field is contagious and will add a 50 - 60 Hertz superimposed signal to any nearby interconnects. Think about what such a mains flex can do to a sub-woofer interconnect; the sub-woofer will play a constant tone of the mains power frequency superimposed on the music or movie signal. Efficient shields are one of Supra's most important design features, you've earned the right to listen to the music only!



Every now and then we hear about creative alternative ways to arrange an earth connection if the wall socket does not provide one. There is especially one we would like to highlight as particularly hazardous and we hope this statement does not serve as yet another creative way. Occasionally the water heat radiators have been connected to the hi-fi gear cabinets or to a mains distribution block earth contact plate. This works normally from the electrical point of view. Until the following happens; one of the devices become faulty and the cabinet becomes energized with wall socket mains voltage. The water radiator system may not be properly grounded to earth potential. Now, this means that there might not be a large enough fault current through the water pipes to blow the fuse, thus disconnecting the fualty device. Further it means that most of the pipings and radiators are energized with wall socket mains voltage. If this is in an apartment house, every neighbour tenant has potentially lethal voltage in their radiators. It will not show. Until e.g. small children touches the radiator. We strongly discourages from the above or any other way to arrange a ground connection other than according to the local laws and regulations for electrical safety.
