The air-helix construction of the Reference Digital-2404 is wholly unique. We have developed a special clip to ensure air insulation that is as close to perfection as possible. A large number of these clips form the supporting structure on the inside of the cable. This holds the signal conductor free in the air in a helix form and guides it through the shielding at defi ned intervals. The fl exibility of this construction is attained with two bridges that hold the clips together evenly and at exact intervals. With coaxial cables, the shielding is usually used as an earth conductor. The Reference Digital 2404 RCA on the other hand has a double-symmetric structure and has two positive and two negative conductors. This means that the shielding is completely separate and the signal remains free of interference. It may seem paradoxical but thanks to this highly innovative air-insulation design, enjoying hi-fi sound becomes a virtually breathtaking experience.
AIR HELIX DESIGN
When it comes to high-end applications, air is still the best insulator currently available as it achieves low capacities and low losses. With NF and Digital cables (fitted with RCA or XLR plugs), these factors are critical for creating an exceptional connection. But consistent design is equally important: The precisely defined distance between the conductors and the shield must be maintained at all times. Flexibility is another key challenge – the cable must allow for conveniently running it behind your hi-fi equipment or rack. Just like all loudspeaker and audio cables from the Referenz series, the Digital 2404 is entirely made in Germany. The clips are meticulously assembled by hand at the on-site factory and then threaded into the Super Speed waveguide. The resulting Air Helix is then provided with a shield and the PE network jacket and finally fitted with GAP-RCA-II or XLR plugs.
SUPER SPEED CONDUCTOR
Obviously, the conductors themselves play a key role, too. For the Digital-2404, they are made of 32 high-purity copper wires braided around a PE core. A very thin lacquer coating on the wires prevents the formation of eddy currents inside this Super Speed waveguide.
HANDMADE BY IN-AKUSTIK
We have long set the bar very high in regard to quality, because cables and connections are extremely sensitive. Physical phenomena that arise during the transmission of signals can only be controlled with technical finesse and the best materials. For this reason all cables are manufactured in a German cable mill and finished by us in Ballrechten-Dottingen in elaborate manual work.
