RCA panel jack

Using this jack adapter, all smartphones, laptops or other devices with a 3.5 mm jack can be easily connected to a mixing console, amplifier, AV receiver or other devices with a 6.3 mm jack socket. It is also suitable for connecting headphones with 3.5 mm jack plugs to hi-fi components with a 6.3 mm jack input.

The Premium doublettes in sandwich design consist of metal disks and special rubber for optimum damping of vibrations between the devices and the locations on which they are standing.

The Exzellenz Bolide shock absorber consists of a special rubber compound and an elaborate lamella design for optimum damping of vibrations between devices and the locations on which they are standing.

High-end and hi-fi systems are a combination of high-precision and filigree devices. Perfectly coordinated, they are capable of reproducing music in outstanding quality. However, in order for the components to work perfectly, they must be kept as free from interference as possible, just like high-precision measuring instruments. The same applies to the connection cables. However, interference can occur in many different ways. In addition to the typical electromagnetic interference, which can be minimized by good shielding, for example, mechanical vibrations and shocks also affect playback quality. The Referenz cable bases have been specially developed for cables. They also have a special gel incorporated in their base and additional natural rubber bands to accommodate the freely suspended cables. As well as absorbing vibrations, the Referenz cable bases also keep the cable at a distance from the floor, reducing unwanted capacitance and the impact on the electronics.

High-end and hi-fi systems are a combination of high-precision and intricately made devices. Perfectly attuned to each other, they allow music to be played back in outstanding quality. To ensure that all components can function flawlessly, they need to be kept free of interference to the greatest extent possible, just like high precision measuring equipment does. The same also applies for the connection cables. Interference is caused in a number of different ways. Along with typical electromagnetic interference, which can, for example, be minimised by using good shielding, mechanical vibrations and shocks also have an impact on the playback quality. Added to this are the effects of capacitive coupling between conductors and floors, which affect loudspeakers cables in particular. The conductors form unwanted capacitance, not just in interplay with each other, but also with other surfaces in the immediate surroundings. A good way to counteract this is by increasing the distance to the surfaces. As a rule, a few centimetres suffice. Vibrations are caused in different ways and they can be transmitted by structure-borne and air-borne noise. Structure-borne noise refers to vibrations that are exhibited by a body, such as the housing of a device. An example of this is the loudspeaker box. The membranes of the speakers are stimulated, making them vibrate. However, as the membranes feature a mechanical connection with the loudspeaker housing, they also transfer vibrations to the housing. The vibrations will be stronger or weaker according to the housing weight and the insulation. The vibrations are also transferred to the surface on which the loudspeakers are placed, this being the floor. Two things now occur. On the one hand, the floor emits some of the structure-borne energy as airborne sound (resulting in the typical droning noise), while on the other hand, the structure-borne noise is transferred, for example, to the cable placed on the floor. More about the effects of this later on. Airborne sound refers to vibrations that are transferred through the air and that are audible for humans (with the exception of infrasound and ultrasound). The primary purpose of a hi-fi system is to produce sound. However, airborne noise not only stimulates the eardrum, but also acts on all other surfaces it reaches. This causes the walls, floors and other surfaces, and ultimately the hi-fi components and cables, to vibrate as well. The combination of airborne and structure-borne noise not only causes glasses in a display case to vibrate mechanically, but all components, including the cable used for a hi-fi signal chain, as well. Experiments have shown that the sound from the components and from the cables is impaired by the vibrations. One reason for this is, for example, the capacity values of components in relation to each other, which constantly change due to the vibrations. In order to minimise these so-called microphonic effects, the components must be isolated from the surface on which they are placed. This can be done by using the Reference High Tech Gel Absorber, for example, for appliances and loudspeakers. Their core contains a special gel, which physically converts the vibrations into heat. The Reference Cable Bases have been developed specifically for cables. Their base also contains a special gel, along with natural rubber strips, in which the cables can float freely. Along with absorbing the vibrations, the Reference Cable Bases also keep the cables at a distance to the floor. This reduces unwanted capacitances and reduces the effects on the electronics.

In the hi-fi, TV and computer sector, most devices need to be connected with a great many signal and power cables. If they are clearly visible, these cables often detract from the overall look or become trip hazards. This high-quality fabric cable conduit allows cables to be bundled together in a visually appealing way. The conduit has been designed so that it can also accommodate power cables with large (Schuko) plugs. It can be easily cut to the required length using a pair of scissors. One notable feature is that, unlike other conduits, the fabric does not fray easily at the ends.

The Star Audio DAC converts digital audio data into analog signals. Its range of applications is very versatile thanks to the optical (TOSLINK) and coaxial (RCA) inputs. The converter can be used, for example, to play the weak sound of a new flat-screen TV via an older but better sounding hi-fi system. The stereo output provides the usual line level and can be connected to the amplifier's AUX or TV input, for example. Power supply unit included. Power supply optionally via plug-in PSU or USB.

High-end and hi-fi systems are a combination of high-precision and fragile devices. Perfectly attuned with each other, they are capable of playing back music in outstanding quality. To ensure that all components can work without interference, just like sensitive measuring equipment they need to be protected as far as possible against vibrations and shocks. Vibrations occur in various ways and can be transmitted by structure-borne or airborne sound. Such problems can be remedied by the use of so-called absorbers. The Exzellenz gel absorbers have a special gel mixture at their core that absorbs vibration energy. This allows you to decouple speakers and devices from the floor. You may think that decoupling the speakers in this way will suffice. However, as described above, there is also airborne sound, which agitates the surfaces of the devices. It is therefore a sensible measure to also decouple the devices from where they are standing. The same advice naturally applies to devices (such as CD players or hard disks) that generate their own mechanical vibrations. Such vibrations need to be prevented from influencing other components.

To ensure that all components can work without interference, just like sensitive measuring equipment they need to be protected as far as possible against vibrations and shocks. Vibrations occur in various ways and can be transmitted by structure-borne or airborne sound. The combination of airborne and structure-borne sound mechanically stimulates all components in the hi-fi chain to vibrate. Studies show that this has a considerable impact on the sound. This Referenz absorber set provides a solid basis for sound without these vibrations. The absorbers have a special high-tech gel at their core which absorbs the vibration energy. For optimum decoupling of the devices and speakers the set includes twelve gel pads for different weight classes.
