Commercial, simple connector strips, how they are to be found surprisingly as a component of high-quality system in many places, have usually an art off housing without any shielding effect and a thin net inlet with small conductor section. Even those models, which give to recognize each other e.g. by thick leads as "audiophil", fail mostly in the crucial places.

Some are additionally equipped with a mini system filter, which are rather harmful however in the relevant spurious frequency range from 51Hz to 100.000Hz (most disturbers concentrate here) ineffectively and because of its additional internal resistance.

The internal wiring in such sockets consists usually of individual, thin wire bridges, whereby the lining up of these pieces of wire and wedge place can lead to a considerable electrical transition resistance. Other constructions again use punched out strips from messing sheet metal, whose specific electrical conductivity, depending upon composition and processing, is worse up to a factor 5 than from pure copper for the connection of the individual doses.

In both cases the compromise-afflicted internal wiring to one unnecessarily high electrical resistance between the individual sockets leads, in particular between their protective grounding contacts. From this a voltage drop (difference of potential) results and with it an interference stream, which must flow off obligatorily over the small frequency cable, with which the devices of the hifi-system among themselves are connected.

This interference stream overlays the music signal, from which it cannot be separated in the following no more. Even potential differences within the millivolt range - thus in the order of magnitude of the audio signal - already mean a sound degradation. It applies to minimize the interference voltage potential i.e., to keep the electrical resistance between the individual sockets as small as possible.

Here the superiority becomes that Fisch Audio-Power Socket Outlet AFL reference line obviously:

Their internal wiring consists of noly-break going through, solid ofc-copper leaders with a conductor cross section of 2,5 mm². Your accurate, measure-exact shaping by a particularly designed bending device is guaranteed. The precise socket elements of the inserted sockets have it an extra high contacting force and a long life span.

By the three pole, shielded mains connection cable with large cross section concern the same high-quality type of cable. Thus the electric stream little resistance opposite and the unwanted voltage drop reduced to a minimum. Besides an effective protection against the in- and out-penetrate of perturbative fields results in connection with the protecting effect of the anodized Aluminium metal housing of the socket.

A high-quality power socket is the first step to a exclusive hifi-system!

The line filter strip - AFL reference line - impressively shows which possibilities can be achieved with adapted and sophisticated network filter technology. This network bar differs significantly from the usual audio power strips. For the first time, a new filter technology was used for this filter strip. This new "on-site" filter technology ensures unrestricted current flow and the best possible interference suppression.

For this effective and elaborate filter technology, a new, in its value adapted housing was constructed. The many years of experience in the development and production of high-quality network filters at FISCH Audio Technology could be implemented without compromise. The main filter is completely invisible to the line frequency, but the high-frequency noise components are effectively suppressed.

In order to eliminate any risk of a loss of dynamics, this completely new filter and a new production technology for the - AFL reference line - have been developed. This is the only way to ensure that the filter can not cause any loss of dynamics.

Powerful power amplifiers are supplied with voltage completely lossless, the sound is reproduced much clearer and more detailed. Each socket is additionally provided with a second filter stage. This filter stage fits uninterruptedly into the supply line to the slot and can not be a "dynamic brake" in principle. This "on-site" filter stage, which is inserted directly into the sockets, has several functions at once. All sockets have a completely identical filtering. They are therefore isolated from each other and rank equally.

The connected devices can no longer influence each other negatively or even interfere. The achieved sound gain goes far beyond the usual measure of a good audio power strip. Even for devices from the absolute top class, where actually no playback improvement is suspected, the gain is immediately and clearly audible. Just like all current-carrying components, the housing has been redesigned uncompromisingly according to audiotechnical findings.

The solid and vibration-optimized design of the housing reliably prevents any kind of mechanical vibrations. Thus, the high-quality housing also contributes to the positive overall result. The quality of workmanship has been set to the highest standards, which are equal to the high level of filter technology. The - AFL reference line - is the best basis for trouble-free and true-to-life music reproduction.
