Amplifier with DSP Match UP 7BMW

Amplifier with DSP Match UP 7BMW

"M-package" for BMW sound system, that's what this amplifier could be called. No one in the world makes such a sophisticated device. Match UP 7BMW is a revolutionary sound upgrade that brings significantly more power and dynamics to the HiFi system. At the same time, however, it takes care of simple installation in the car. This is done literally in an instant. The package includes a panel exactly fitting the place of the original amplifier and exactly fitting cabling. Just unscrew and disconnect the original amplifier and connect the UP7 BMW. The size of this device may have In reality, however, it is a full-fledged seven-channel amplifier with state-of-the-art HD technology and a 64 Bit DSP processor. It can even be enhanced with Bluetooth ^® Audio Streaming Modul or High Resolution Audio USB slots. Thanks to this, you can create a concert hall from your "ordinary" system while playing music in the highest possible quality.

HD class technology

UP 7BMW combines the advantages of Class H technology with the principle of a Class D amplifier. The result is an unsurpassed level of efficiency, which again surpasses conventional Class D amplifiers. The advantages of the Class HD concept are manifested at low and medium modulation levels, as the power supply regulates the internal supply voltage power stages depending on the amplitude of the input signal. This drastically reduces the average power loss generated by the amplifier.

Intelligent high-level input ADEP.3

Modern, factory-installed car radios are becoming more intelligent when it comes to diagnosing connected speakers. In particular, the latest generation of BMW car radios are equipped with additional monitoring functions, so error messages or even malfunctions may occur when an additional amplifier is connected. The new ADEP.3 (Advanced Diagnostics Error Protection Generation 3) circuit prevents these problems without unnecessarily loading the radio's speaker outputs at high levels.

Start-Stop capability

The power supply in the UP 7BMW amplifier provides internal power even with short-term drops of up to 6 volts. This ensures that the amplifier remains fully functional even when the engine is started. If the voltage on the board drops below 10.5 volts for more than 5 seconds, the amplifier will go into "Protect Mode" (status LED is solid red) to prevent further discharge of the battery.

Automatic digital signal detection

Switching between analog and digital input is controlled by a signal. As soon as an audio signal is detected at the optical input, the amplifier switches to this input. This function can be deactivated in the DSP PC-Tool or alternatively manual control can be selected using the optionally available remote control.

Power saving mode

The power saving mode allows you to drastically reduce the power consumption of the UP 7BMW amplifier (and any other connected amplifiers) if there is no input signal for more than 60 seconds. When "Power Save Mode" is active, the UP 7BMW's internal amplifier stages and remote output are switched off, significantly reducing power consumption. The amplifier will return to normal operation within 2 seconds as soon as there is a music signal at its input. The switch-off delay can be changed or completely disabled using the DSP PC-Tool software.

RealCenter

The "RealCenter" function is Audiotec Fischer's proprietary algorithm that emphasizes the monophonic information of the left and right front channels to create a unique center signal. Unlike the usual method in which only the channels are summed, there is also dynamic control of the center signal through the stereo information content of the left and right channels. This means that the center channel does not reproduce the signal if only the left channel or only the right channel provides the audio signal. With the usual algorithms, the center channel would be only 6 dB quieter in this case. The "RealCenter" from Audiotec Fischer thus enables a unique, wide view of the stage - and that's ideal for both driver and passenger! The disadvantages of a conventional center channel, such as distracting, narrow spatial sound imaging, are finally a thing of the past.

Advanced bass processing

Audiotec Fischer's proprietary "Augmented Bass Processing", consisting of two revolutionary sound functions: "Dynamic Bass Enhancement" and "SubXpander". These are specifically designed to dramatically improve bass response from subwoofers. "Dynamic Bass Enhancement" ingeniously combines extremely deep bass and high maximum sound pressure - regardless of the type of music you're listening to or the sound settings on the radio. Depending on the input signal, "Dynamic Bass Enhancement" on the one hand boosts the lower frequency range and on the other hand changes the cutoff frequency of the subsonic filter. The result is significantly more powerful, deeper bass reproduction at low and medium volumes without the risk of mechanical or electrical overload of the subwoofer at high volumes. It's just fascinating what kind of bass performance is suddenly possible. If you want the bass range to be a bit deeper and "blacker", you can also activate "SubXpander". Here, additional subharmonic tones are added to the fundamental tones in the frequency range between 50 and 100 Hz.

StageXpander

Depending on the arrangement of the speakers in the vehicle, a more or less wide stereo stage can be created on the front seats. If a center speaker is also installed, sometimes this also limits the spatial reproduction of music. This is where the new Audiotec Fischer "StageXpander" comes into its own - a sound function that seems to remove acoustic boundaries, allowing for a significantly wider stereo base without negatively affecting the accuracy in the localization of voices or instruments. The effect can be adjusted according to personal taste in four stages.

ClarityXpander

Would you like more transparency and substance in high frequency reproduction? Audiotec Fischer now offers exactly the right tool for this with the "ClarityXpander". When properly dosed (and thus selectable in three stages), it adds extra radiance to the undertones - especially useful if the original speakers lack the necessary high-frequency sparkle. Extra high kick is not only available for the two front channels, but also separately adjustable for the center channel. And since, especially with the latter, in connection with musical material rich in aliquots, it is too much, tiring the ear, the automatic dynamic control of the additional aliquot component can even be activated here.
