LoRad means LOw RADiation and the design of this cable minimises both electrical and magnetic fields. LoRad protects both from fields radiating from the cable as well as pick-up of surrounding noise fields, e.g. wireless and mobile phones, radio broadcasts, etc. LoRad MkII is a development of the Lorad concept, now with improved shielding properties, flexibility, bend-resistance and strength.
- LoRad stands for Low Radiation of electric and magnetic alternating fields
- The screen protects your equipment from radiated mains noise and from RF pick-up.
- Short pitch twisting of the cores cancels the magnetic alternating fields.
- This will result in a cleaner sound and more accurate transients.
The radiation is lowered by means of two techniques. First the shield minimises the alternating electrical fields from the cable. It also minimises the RF pick-up (Radio Frequency). The magnetic fields are cancelled by twisting the conductors in a short pitch.
The benefits are cleaner sound, pronounced transients and an improved 3D soundstage. We also hear customers describe more detailed sound and we are not surprised. If your equipment is installed using SUPRA cables, the noise floor is generally suppressed by several dB, allowing more of the content to be revealed. Low radiating cables is also increasingly important from a health point of view. Science has proven that alternating magnetic fields affects cell growth.
The biggest differences between LoRad MkII and the old LoRad cable, is that it is now based on SUPRA’s unique Nylon screen concept. Semiconducting Nylon Screen provides improved shielding properties, bending strength, environmental immunity, higher tensile strength and less microphonic effect. The Nylon screen is connected with a drain-wire. Supra have tested and evaluated all known types of screens for making such a good cable as possible. SUPRA’s semi-conductive Nylon screen was the only one that passed the safety requirements and, moreover, its shielding properties was best in test. LoRad MkII is tested and certified by Intertek Sweden, meeting the European safety regulation HD21.5 S3.
The cable must be connected to a wall socket with a ground terminal for the full LoRad effect.
