The mains blocks are fully shielded from radiated electric fields by means of their aluminium chassis. The conductive chassis drains the interference down to ground. It has to be connected to an earthed socket with an earthed mains cable, in order to work properly. For a useful degree of shielding and immunity, the mains block should be combined and employed with SUPRA LoRad shielded mains cables
The new EU Mk3 mains blocks are greatly improved. Even better connectors, filter and surge protection. All parts are either made in Germany and Sweden. Assembling in the Supra factory, Ljungskile, Sweden.
Radiation Free, with Non-Intrusive Filtering and 3-way Surge Protection
6 Schuko EU sockets, fully shielded in Aluminum
NIF-filter, Shielded, Ceramic fuse 10A
A shielded mains distribution block in Aluminum with surge protection. Free from noise deriving from a variety of noise fields from e.g. cell phones, DECT phones, dimmers and many other domestic electrical equipment? SUPRA MD is a sound and performance enhancing mains distribution strip, containing a proprietary SUPRA NIF, Non-Intrusive Filtering circuitry, providing a mild noise and radio frequency filtering that will not slow down or mute the dynamics from your Hi-Fi audio system. The conscious Hi-Fi enthusiast connects the Supra MD mains distribution strip only to wall sockets with earth terminal using Supra LoRad mains flex (optional).
Radio frequency interference reduced by 40dB!
Internal wiring of 2.5sqmm oxygen free copper leads
Supports a staggering 2300W of continuous power!
Protects you and your Hi-Fi audio system from harmful noise fields and radiation!
Suitable for wall mounting
Multi-way Surge Protection.
When other manufacturers stop at one-way protection, i. e. only between the live and neutral lead from the power source, Supra goes all-in and offer a full three-way protection required to protect your HiFi audio system from e.g. a nearby lightning strike. The conscious HiFi enthusiast connects the Supra MD mains distribution strip only to wall sockets with earth terminal using Supra LoRad mains flex (optional).
SUPRA NIF Transient Filter
A Non-Intrusive Filtering circuitry, providing a mild noise and radio frequency filtering that will not slow down or mute the dynamics from your Hi-Fi audio system.
SUPRA Mains block must be connected to a ground terminal socket for the various protections and filters to be active
