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).
All models are equipped with Supra NIF ( N
on- I
ntrusive F
iltering), 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; http://www.jenving.com/products/view/ac-sensor-110-230v-1071100026
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!
