Special features:

Class GD technology

Audiotec Fischer's unique Class GD concept combines the advantages of Class G technology with the principle of a Class D amplifier.
This results in an unusually high level of efficiency that surpasses that of conventional Class D amplifiers. The Class GD concept shows its advantages at low and medium levels by varying the internal supply voltage of the power stages in stages depending on the amplitude of the input signal. This drastically reduces the average power loss generated by the amplifier.

ACO - Advanced 32 Bit CoProcessor

The MATCH UP 8DSP amplifier uses a particularly powerful 32-bit CoProcessor of the latest generation. This not only handles all control tasks ultra-fast, but also the lightning-fast switching between up to ten possible sound setups. But ACO offers much more - in addition to a channel-separated Input EQ including Input Signal Analyzer (ISA) for easy analysis and compensation of input signals from OE radios and fantastic sound effects such as Augmented Bass Processing or RealCenter, there is now the revolutionary TuneEQ function for automated adjustment of the output equalisers. Another significant advantage is the integrated, native bootloader of the CoProcessor. This enables software upgrades of all components of the DSP, for example to adapt the microcontroller-controlled ADEP.3 circuit to changes in diagnostic systems of factory radios in the future or to expand the device with additional interfaces.

Intelligent high-level input ADEP.3

Modern, factory-fitted car radios are becoming increasingly intelligent in terms of diagnosing the connected speakers. The latest generation in particular is equipped with additional monitoring functions so that error messages or even malfunctions can occur if an additional amplifier is connected. The new ADEP.3 circuit (Advanced Diagnostics Error Protection Generation 3) prevents these problems without unnecessarily overloading the radio's speaker outputs at high levels.

Start-stop capability

The power supply unit in the UP 8DSP amplifier ensures the internal power supply even in the event of short-term dips down to 6 volts. This ensures that the amplifier remains fully functional even when the engine is started. If the on-board voltage drops below 10.5 volts for longer than 5 seconds, the amplifier switches to "Protect Mode" (status LED lights up red continuously) to prevent further discharging of the battery.

Automatic Digital Signal Detection

The UP 8DSP allows signal-controlled switching between the analogue and digital inputs. As soon as an audio signal is detected at the optical input, the amplifier switches to this input. This function can be activated in the DSP PC-Tool software or, alternatively, manual control can be selected using an optionally available remote control.

Power save mode

The Power Save mode allows the power consumption of the UP 8DSP (and any additional amplifiers connected) to be drastically reduced if no input signal is present for longer than 60 seconds. As soon as the "Power Save Mode" is active, the internal amplifier stages of the UP 8DSP and the remote output are switched off, thus significantly reducing the power consumption. The amplifier returns to normal operating mode within 2 seconds as soon as a music signal is applied to its input. The switch-off delay can be varied or completely deactivated using the DSP PC-Tool software.

DSP features

TuneEQ

TuneEQ is an extremely flexible and particularly easy-to-use function for automated frequency response correction. A single measurement per respective audio channel or channel pair with a suitable measurement microphone (such as our MTK1) is sufficient for TuneEQ to adjust the equalisers independently and precisely to the desired reference curve. TuneEQ uses the entire range of functions of the parametric equaliser, including the centre frequency, the Q factor and the gain. And because the highly complex computing operations required for this run in the background, you also save a lot of time when tuning the sound with TuneEQ.

RealCentre

The "RealCenter" function is a proprietary algorithm from Audiotec Fischer that emphasises the monaural information of the left and right front channels to create a unique centre signal. In contrast to conventional methods, where only the channels are summed up, the centre signal is also dynamically controlled by the stereophonic information content of the left and right channels. This means that the centre channel does not reproduce a signal if only the left or only the right channel delivers an audio signal. With conventional algorithms, the centre channel would only be 6 dB quieter in this case. Audiotec Fischer's "RealCenter" therefore enables a unique, wide-ranging soundstage - and this is optimal for both driver and front passenger! The disadvantages of a conventional centre channel, such as an intrusive, narrow spatial sound reproduction, are finally a thing of the past.

Augmented bass processing

Audiotec Fischer's proprietary "Augmented Bass Processing", consisting of two revolutionary sound features: "Dynamic Bass Enhancement" and "SubXpander". These have been specially developed to dramatically improve the bass reproduction of subwoofers.

"Dynamic Bass Enhancement" ingeniously combines maximum low bass foundation and high maximum sound pressure - regardless of the type of music you are listening to or the sound settings on the radio. Depending on the input signal, "Dynamic Bass Enhancement" boosts the lower frequency range on the one hand and varies the cut-off frequency of the subsonic filter on the other. The result is a much more powerful, deeper bass reproduction at low and medium volumes without running the risk of mechanically or electrically overloading the subwoofer at high volumes. The bass performance that is suddenly possible is simply fascinating.

If you want the bass range to be a little deeper and "blacker", you can also activate the "SubXpander". Here, subharmonic tones are added to the fundamental tones in the frequency range between 50 and 100 Hz.
