на 12 вноски по 127.86 лв.

Аудио концепцията BMW RAM (Receiver Audio Module) започва да се вгражда серийно в различните модели на BMW от средата на 2019г. За инсталация на ъпгрейд усилвател към фабричната аудио система (Standart и Hi-Fi) са необходими поне 6 входа по високо ниво към новия DSP усилвател. Това прави усилвателя Match UP7DSP с вградена допълнителна платка MEC Analog IN перфектният ъпгрейд усилвател за тези модели фабрични аудио системи на BMW.

При инсталация на Match UP7DSP BMW Ram upgrade фабричният усилвател RAM не трябва да се деинсталира. Оригиналното захранване в този случай не е достатъчно и е необходимо Match UP7DSP BMW RAM Upgrade да се захрани директно от акумулатора на автомобила. Тази манипулация е сравнително лесна, тъй като акумулаторът е близо.

DSP Features:

The “RealCenter” feature is an algorithm, developed by Audiotec Fischer, that emphasizes the music information which is present in both the left and right front channel to create an unique center signal. In contrast to common procedures in which only the channels are summed up, the intensity of the center signal is also dynamically controlled by the stereophonic informational content of the left and right channel. Sounds complicated but this effect is astonishing: That means if solely the left or right channel delivers 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” allows a unique, broadened sound staging for both driver and co-driver at the same time! Therefore, the disadvantages of a conventional center channel such as an intrusive, small sound stage are things of the past.

Augmented Bass Processing
Audiotec Fischer’s proprietary “Augmented Bass Processing”, consisting of the two revolutionary sound features “Dynamic Bass Enhancement” and “SubXpander”, has been especially developed to dramatically improve the bass reproduction of subwoofers.
The “Dynamic Bass Enhancement” ingeniously combines maximum deep bass and highest sound pressure – regardless of the music style or the tone controls in the head unit. Depending on the input signal, the “Dynamic Bass Enhancement” gains the lower frequency range and varies the cut-off frequency of the subsonic filter. The result is a significantly more powerful and deeper bass response at low and medium volume levels without the risk of overloading the subwoofer, neither mechanically nor electrically at high volume levels. It is simply fascinating which bass performance is suddenly possible.
If you want an even lower and “darker” bass reproduction, the “SubXpander” can be additionally activated. Therefore, subharmonic tones are added to the fundamental tones in the frequency range between 50 and 100 Hz.

Depending on the speaker arrangement in the vehicle, a more or less wide stereo sound stage can be created at the front seats. A center speaker may limit the spatial reproduction of the music additionally. This is where Audiotec Fischer’s new “StageXpander” comes into play – a sound feature which seems to break the acoustic limitations and thus allows to create a way broader stereo base without negatively affecting the precision of the localization of voices or instruments!
The effect can be adjusted according to your personal preferences in four steps.

You are looking for more transparency and substance in the treble reproduction? With the “ClarityXpander” Audiotec Fischer is now offering the right tool.
Properly adjusted (and therefore selectable in three steps) the feature adds additional harmonics in the upper frequency range – this is especially useful if the original speakers lack some brilliance in the treble response. The extra treble-kick is not only available for the two front channels but also separately adjustable for the center channel.
Even better – the center channel allows to activate an automatic and dynamic control so that music with “loads” of treble doesn’t fatigue your hearing.
