The good old LP sounds more alive than ever. Even experts would not have thought this demand possible. The sales of LPs are rising just as surprisingly as those of record players. A boom. But how can the sound be improved? For example, using a new, superior cable between the pick-up arm and the phono amplifier. We at in-akustik have created a new cable for excellent sound – the Reference Phono 2404. It is distinguished by an absolutely unique air insulation feature known as air-helix. We have developed a special clip for this. It separates the two cable strands, keeping them at a distance and embedding them in air, so to speak. Using a large number of these clips the ground and the signal path can be extended over long distances while maintaining extreme stability. Why make the effort? In this way it is possible to forward the sensitive signal without insulation slowing it down – the result is a high-resolution, fast sound. The Super Speed waveguides are threaded and fitted with clips by hand with extreme care in our own manufacturing unit. Afterwards the air-helix created in this manner is given ist shielding and PE network jacket – again by hand. Finally the rhodium-coated plugs are fitted and the cable function is tested. This is because the signals are very important and very small – nowhere else in the audio world are smaller currents used. And they must be forwarded perfectly. The signal level of an MM or MC system is extremely sensitive, at just a few thousandths of a volt. Additionally, the systems have an inductive character. In combination with the cable capacity, they form what is known as an oscillating circuit, which favours specific frequencies. If these frequencies are unfavourable due to excessively high capacities, this has a major effect on the harmony of the sound. Extremely low capacities and dielectric losses are only two advantages of Reference Phono 2404. They form the basis of your unadulterated enjoyment of your vinyl treasures. There is no finer resolution for the sound of good LPs.

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 Phono 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 rhodium coated plugs.

SUPER SPEED CONDUCTOR

Obviously, the conductors themselves play a key role, too. For the Phono-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.
