Digital Opto

With the Exzellenz digital cable, the sensitive audio data is also optimally protected against external interference by two separately routed shields. The digital music signal is transported precisely (low jitter) thanks to the silver-plated conductor and the perfectly-adapted impedance, so that a natural and dynamic sound is guaranteed, even with high-resolution audio formats. Solid, 24k gold-plated metal plugs ensure optimum contact and minimal contact resistance on a long-term basis.

High-quality optical cable (fiber optic cable) with precisely fitting and standardized TOSLINK and miniplug connectors for the secure and interference-free connection of digital audio sources such as CD, DVD, Blu-ray players or games consoles to the AV receiver. Typical application examples are Apple TV, Apple MAC Pro and Apple Airport Express, as well as other devices with combined 3.5 mm audio output (stereo headphones + optical digital in one socket). The virtually interference-free transmission brings tremendous advantages. Optical cables are resistant to electromagnetic interference (EMI) and radio frequency interference (RFI) because they use light instead of electrical current. This enables reliable and virtually interference-free signal transmission, even in environments containing many electronic devices.

The conductor of the Exzellenz optical cable consists of a special polymer fiber (PMMA) and is fitted with high-quality, solid TOSLINK connectors. An elaborate assembly process reduces light refractions in the fiber and also any jitter effects to a minimum. This brings a natural, dynamic and homogeneous sound even with high-resolution audio formats.

The optical digital cable with standardized TOSLINK connectors for connecting up digital audio sources such as CD, DVD, Blu-ray players or games consoles to AV receivers etc. An outstanding advantage is the virtually interference-free transmission. Optical cables are resistant to electromagnetic interference (EMI) and radio frequency interference (RFI) because they use light instead of electrical current. This enables reliable and virtually interference-free signal transmission, even in environments containing many electronic devices. Application: TOSLINK is used in a variety of devices, including home theater systems, televisions, DVD players, game consoles and audio devices. It is a widely used standard for digital audio transmission.

The Air Helix architecture of the Referenz Digital-2405 AIR is absolutely unique. We have developed a special clip that enables us to come as close as possible to perfect air insulation. Inside the cable, a large number of these clips form the supporting structure that keeps the helically-arranged conductors apart in the air and guides them through the shielding at a defined distance from each other. Cable flexibility is assured by means of two struts that ensure the clips remain together but also at a precise distance from one another. With coaxial cables, the shielding is generally also used as a ground wire. The Referenz Digital 2405, on the other hand, has a double-symmetric design with two positive and two negative conductors. This means that the shielding is completely separate and the signal remains free of interference. Even if it sounds paradoxical, thanks to the innovative air insulation in this cable, hi-fi becomes a simply breathtaking sound experience. Click here and discover the exciting details

With the Digital-2405 AIR Pure Silver, the digital member of the AIR family is now also available as a pure silver cable. The dimensions, structure and arrangement of the conductors correspond to the respective copper versions. As with the LS-4005 AIR Pure Silver, LS-2405 AIR Pure Silver and LS-1205 Pure Silver, the signal conductors have been optimized. AIR technology is a milestone in our more than 40-year company history and is causing a sensation in the hi-fi industry worldwide. The approach itself sounds relatively banal: The physically induced losses must be minimized in order to transmit the original music signal as authentically and neutrally as possible. And, thanks to the AIR technology, loss-free transmission is closer than ever before. It leads to significantly better sound reproduction, which is not only subjectively audible but also objectively measurable. The insulation (or dielectric) of the AIR cables is practically perfect thanks to the air insulation, and hardly affects the sound at all. The structure, dimensions and arrangement of the conductors are optimized, and approach the limits of what is physically possible. Adding another highlight to this perfect audiophile foundation, we then focused on the conductor material of the cables. Copper in the appropriate purity is already a very good conductor. A superconductor, where electrical resistance is zero, would be perfect, of course. Unfortunately, superconducting materials require temperatures of at least -70 degrees. Under realistic operating conditions, the best conducting material we have is currently silver. At 61.35 S/m (Siemens pro Meter), its conductivity is approximately six percent superior to that of copper. However, this precious metal is about 100 times more expensive.

The S25 Digital Cable meets the highest standards of sonic fidelity and technical precision in digital signal transmission. With its precisely matched impedance of 75 ohms, it is perfectly suited for all common digital audio interfaces and guarantees lossless, low-jitter transmission - even with high-resolution formats. The signal conductors are made of highly pure, oxygen-free OFC copper and insulated with foamed polyethylene (PE). This dielectric, containing microscopically enclosed air bubbles, ensures particularly low capacitance, minimizes signal loss, and preserves the integrity of even the finest digital signals. A dense copper braid made of 186 fine strands effectively shields the signal from external interference such as Wi-Fi, Bluetooth, or mobile networks. The robust, highly flexible construction and discreet design allow for easy and seamless integration into any hi-fi system. Gold-plated solid metal connectors ensure consistently low contact resistance and reliable connectivity - even after many plug cycles. Each cable is manufactured in Germany and individually tested for signal continuity to ensure uncompromising quality and long-lasting performance. Click here to discover exciting details
