The "RealCenter" function is an algorithm, developed by Audiotec Fischer, which emphasizes the music information present in the front left and right channel to create a unique center signal. Contrary to common procedures, in which only the channels are summarized, the intensity of the central signal is also dynamically controlled by the stereophonic information content of the left and right channel. It sounds complicated but this effect is amazing: this means that if only the left or right channel is providing an audio signal, the center channel will not reproduce a signal. In the case of common algorithms, the volume level of the center channel is only reduced by 6 dB (= half volume level). Audiotec Fischer's "RealCenter" enables a unique and expanded sound staging for driver and co-driver at the same time! Therefore, the disadvantages of a conventional center channel, such as a small intrusive soundstage, are a thing of the past.

Audiotec Fischer's proprietary "Augmented Bass Processing", consisting of the two revolutionary sound functions "Dynamic Bass Enhancement" and "SubXpander", was specially developed to significantly improve the bass reproduction of subwoofers. The "Dynamic Bass Enhancement" ingeniously combines deep bass and maximum sound pressure, regardless of the musical style or the tone controls in the headunit. Depending on the input signal, "Dynamic Bass Enhancement" gains the lower frequency range and varies the cutoff frequency of the subsonic filter. The result is significantly more powerful and deeper bass response at low and mid volume levels without the risk of overloading the subwoofer either mechanically or electrically at high volume levels. It is simply fascinating what bass performance is suddenly possible. If you want an even lower and "darker" bass reproduction, you can also activate "SubXpander". Thus, subharmonic tones are added to the fundamental tones in the frequency range of 50 to 100 Hz.

Depending on the loudspeaker arrangement in the vehicle, a more or less wide stereo stage can be created in the front seats. A center speaker can further limit the spatial reproduction of music. This is where Audiotec Fischer's new “StageXpander” comes into play, an audio function that appears to break acoustical limitations and thus allows you to create a wider stereo base without negatively affecting the accuracy of locating vocals or instruments! The effect can be adjusted to your personal preference in four steps.

Looking for more transparency and substance in treble reproduction? With the "ClarityXpander" Audiotec Fischer now offers the right tool. When properly adjusted (and therefore selectable in three steps), the function adds further harmonics in the upper frequency range; this is especially useful if your original speakers lack some sparkle in their treble response. The extra treble kick is not only available for the front two channels, but is separately adjustable for the center channel. Even better: the center channel allows you to activate an automatic dynamic control so that music with "loads" of treble does not tire your ears.
