MATCH UP 8BMW MK2

“M-Power” for your BMW HiFi sound system

The MATCH UP 8BMW MK2 is the plug-and-play "M package" for BMW HiFi sound systems: It combines a powerful 8-channel Class GD amplifier with an integrated 9-channel DSP, delivering power and dynamics for an impressive HiFi upgrade – while maintaining near-OEM, clean integration into the vehicle. Designed for BMW E and F models as well as G30/G31 (pre-facelift) with HiFi sound system (option 676), installation is carried out in the original mounting location using the included plug-and-play connection cable and a BMW-specific mounting solution.

In the MK2 generation, the concept has been further refined and brings important updates for modern and expandable system integration, including a USB-C port and an Extension Card 2.0 slot. As the centerpiece of a scalable BMW upgrade concept, the UP 8BMW MK2 can be ideally combined with other MATCH BMW components and HELIX COMPOSE loudspeakers.

Seamless connectivity and powerful performance in a compact format

For connection to existing factory systems, the UP 8BMW MK2 offers six high-level inputs for tapping the OEM speaker signals (including  ADEP.3 for safe operation on many factory radios) as well as an additional optical digital input for integrating digital sources.

On the output side, eight amplifier channels are available, including 6 x 65 watts RMS @ 4 Ω and two power channels for subwoofers or powerful woofers with up to 2 x 90 / 160 watts RMS @ 4 / 2 Ω maximum output power – in combination with 9 processed DSP channels for precise signal processing and flexible sound tuning.

The UP 8BMW MK2 combines performance and connectivity in a compact, space-saving design and gains additional expandability in the MK2 generation: The new Extension Card 2.0 slot is used, a redesigned expansion system with a screw-on plastic cover and cross-series compatibility. This allows the system integration to be expanded modularly as needed, for example with Bluetooth® HD  or additional analog or digital inputs. The USB-C port also ensures modern access via DSP PC tools.

ACO – Advanced 32 Bit CoProcessor Platform

The UP 8BMW MK2 is of course equipped with the proprietary 32-bit ACO platform – this not only handles all control tasks ultra-fast, but above all offers a whole bundle of audio functions: Fantastic  sound effects such as Augmented Bass Processing or RealCenter are implemented, as well as a channel-separated input EQ including  Advanced Input Signal Analyzer (AISA) for easy analysis and compensation of the input signals from OE radios that already include a sound setup from the factory.

DSP PC-Tool 6 feat. TuneEQ – Powerful features for ultimate sound experiences

Naturally, the MATCH UP 8BMW MK2 can be configured using our professional and exceptionally intuitive  DSP PC-Tool 6. The familiar, numerous settings leave nothing to be desired and guarantee extremely precise sound adjustment, even with complex system configurations. And thanks to the new, proprietary TuneEQ 2.0 and the TuneToTarget function for automated frequency response correction, you also save a considerable amount of time when tuning your sound.

Virtual Channel Processing – this is how signal routing works today

Optimal integration with existing multi-channel sound systems necessitates intelligent management and configuration of the amplifier's numerous DSP channels. Especially when front, rear, and center speakers are divided into various active multi-way systems, conventional routing concepts quickly reach their limits in terms of both implementation and usability. The multi-stage " Virtual Channel Processing, " in conjunction with the renowned user-friendly DSP PC-Tool software, allows even highly complex system configurations to be easily mapped and our proprietary FX sound features to be freely assigned.

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 exceptionally high efficiency that surpasses even conventional Class D amplifiers. The Class GD concept demonstrates its advantages at low and medium output levels by varying the internal supply voltage of the power stages in steps depending on the amplitude of the input signal. This drastically reduces the average power dissipation generated by the amplifier.

ACO – Advanced 32 Bit CoProcessor

The ACO (Advanced CoProcessor) platform handles all control and communication tasks within the DSP system. It ensures extremely fast system startup, lightning-fast switching between up to ten sound setups, and smooth, latency-free data communication with the DSP PC-Tool software.

Furthermore, ACO forms the basis for numerous additional functions – including our SFX sound effects such as "Augmented Bass Processing" and "RealCenter", features like Dynamic Loudness Control (DLC) and Remote Tone Control (RTC), as well as a channel-separated input EQ with integrated Advanced Input Signal Analyzer (AISA) for easy analysis and correction of input signals that already include factory equalization. ACO thus stands for maximum performance, flexibility, and future-proofing.

Intelligent high-level input ADEP.3

Modern, factory-installed car radios are becoming increasingly intelligent in their diagnostics of connected speakers. The latest generation, in particular, is equipped with additional monitoring functions, which can lead to error messages or even malfunctions when an additional amplifier is connected. The ADEP.3 circuit (Generation 3) meets the latest requirements of modern OEM car radios and ensures seamless integration. Controlled via the ACO platform, the system is future-proof and can flexibly adapt to future changes in the diagnostic systems of factory radios. This guarantees maximum compatibility with virtually all OE radios – without placing unnecessary strain on the speaker outputs at high volume levels.

Power Save Mode

The Power Save mode reduces the power consumption of the amplifier (and any additional connected amplifiers) when no music signal is detected for a certain period.

When Power Save mode is activated, the internal amplifier stages and the remote output automatically switch off. If a music signal is subsequently detected, the device returns to normal operation within approximately 2 seconds.

The shutdown delay can be adjusted or completely disabled using the DSP PC-Tool software.

Start-stop capability

The power supply in the MATCH UP 8BMW MK2 amplifier ensures a stable internal voltage supply even during brief drops down to 6 volts. This guarantees that the amplifier remains fully functional even when the engine is started.

DSP Features

TuneEQ

TuneEQ is an extremely flexible and exceptionally easy-to-use function for automated frequency response correction. A single measurement per audio channel or channel pair with a suitable measurement microphone (such as our AMI Tuning Kit) is all it takes for TuneEQ to automatically and precisely adjust the equalizer to the desired reference curve. TuneEQ utilizes the full functionality of the parametric equalizer, including center frequency, Q factor, and gain. And because the necessary, highly complex calculations run in the background, TuneEQ also saves a significant amount of time when tuning your sound.

RealCenter

The "RealCenter" function is a proprietary algorithm from Audiotec Fischer that emphasizes the monaural information of the left and right front channels to create a unique center signal. Unlike conventional methods that simply sum the channels, this system dynamically controls the center signal based on the stereo information content of the left and right channels. This means that the center channel will not reproduce a signal if only the left or only the right channel is delivering an audio signal. With conventional algorithms, the center channel would only be 6 dB quieter in this case. Audiotec Fischer's "RealCenter" thus enables a unique, wide soundstage – optimal for both driver and passenger! The disadvantages of a conventional center channel, such as an intrusive, narrow spatial soundstage, are finally a thing of the past.

Augmented Bass Processing

Audiotec Fischer's proprietary "Augmented Bass Processing" consists of two revolutionary sound features: "Dynamic Bass Enhancement" and "SubXpander." These are specifically designed to dramatically improve the bass response of subwoofers.

"Dynamic Bass Enhancement" ingeniously combines maximum deep bass foundation and high maximum sound pressure level – regardless of the music genre or radio settings. Depending on the input signal, "Dynamic Bass Enhancement" amplifies the lower frequency range and simultaneously varies 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 mechanically or electrically overloading the subwoofer at high volumes. The suddenly achievable bass performance is simply fascinating. 

For those who want even deeper and "blacker" bass, the "SubXpander" can also be activated. Here, subharmonic tones are added to the fundamental tones in the frequency range between 50 and 100 Hz.
