Preterminated MKII Lo-Rad including factory-installed IEC-320 and SW-US-plug!
LoRad means LOw RADiation and minimize both electrical and magnetic fields. LoRad protects both from fields radiating from the cable and 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.
The radiation is lowered by means of two techniques. First the shield minimizing the alternating electrical fields from the cable. It also minimizes 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 are 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. We 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. The screen protects the cable from electric fields and the short pitch twisted conductors helps to cancel out magnetic fields. This will typically result in a cleaner sound and more accurate transients, which in turn give you a tighter bass, better 3-Dimension presence and stereo definition.
The secret of LoRad is the yellow/green earth conductor. Normal shielded cables have 4 conductors: blue, brown, yellow/green and one uninsulated wire in contact with the shield. So far, it has not been possible to pass the safety test for flex use with this naked drain wire as it cuts and damages the cable inside when the cable is repeatedly moved and bent. As usual, SUPRA did something unexpected. The yellow/green earth conductor was instead insulated with semi-conductive plastic. No drain wire is needed anymore and the cable passed the flex test. The cable is electrically shielded as the foil is in connection with the semi-conductive plastic on the earth conductor.
LoRad MkII is tested and certified by Intertek Sweden, meeting the European safety regulation HD21.5 S3. LoRad is the only shielded cable meeting the European safety regulation HD 21.5 S3. The cable must be connected to a wall socket with a ground terminal for the full LoRad effect.
