The efficient upgrade for classic OEM sound systems
The UP 4DSP expands the MATCH UP lineup with a 4-channel amplifier with an integrated 5-channel DSP: the ideal solution for vehicles equipped with simple 2- or 4-channel factory radios where a clearly audible improvement in sound quality is desired – without the complexity of larger multi-channel amplifiers. It is purpose-built to significantly enhance factory sound systems while ensuring clean, unobtrusive integration into the vehicle.
With optional plug-and-play harnesses and an intelligent 4-channel high-level input featuring ADEP.3, the UP 4DSP integrates seamlessly into modern OEM architectures. Its compact size and high efficiency make it the perfect choice for daily drivers, lease vehicles or installations with very limited space – anywhere a high-quality, space-saving and fully everyday-ready upgrade is needed.
Compact Class-D power and integrated DSP for flexible OEM upgrades
The UP 4DSP combines four highly efficient amplifier channels with an integrated 5-channel DSP, providing precise control and solid output power for common loudspeaker configurations.
The two main channels deliver 2 x 60 Watts RMS @ 4 Ω, offering ideal performance for driving a front speaker system. For subwoofer upgrades, two additional channels supply 2 x 85 Watts RMS @ 4 Ω or 2 x 140 Watts RMS @ 2 Ω, forming a strong foundation for compact bass enhancements.
Connectivity and system expansion have also been carefully considered: the mono RCA outpit enables connection of external amplifiers, while the optical SPDIF input allows seamless integration of digital sources or aftermarket head units. The start/stop-ready power supply with an extended operating voltage range up to 18 V ensures full compatibility with modern vehicle platforms, including hybrid and electric models.
Compact design for flexible installation options
The UP 4DSP impresses with its powerful yet compact design, which allows easy installation even in confined spaces.
ACO – Advanced 32 Bit CoProcessor platform
Of course, the UP 4DSP is equipped with our proprietary 32 Bit ACO platform, which doesn’t just take over all control tasks ultra-fast, but also handles a bunch of audio functions: fantastic sound effects such as Augmented Bass Processing or Real Center are implemented as well as a channel-separated Input EQ including Input Signal Analyzer (ISA) for easy analysis and compensation of input signals of OE radios, which already include a sound setup by default.
DSP PC-Tool 6 feat. TuneEQ – Powerful features for the ultimate sound experience
Of course, the MATCH UP 4DSP can be easily configured via our professional and exceptionally intuitive DSP PC-Tool 6. The familiar, numerous setting options leave nothing to be desired and guarantee an extremely precise sound adjustment even for complex system configurations. And thanks to the new, proprietary TuneEQ function for automated frequency response correction, you also save a lot of time when optimizing your sound.
Features
- Ultra efficient 4-channel amplifier with 1-channel line output and 5-channel DSP
- Perfect for upgrading standard sound systems with up to 4 channels
- Optional cable harnesses for easy integration into existing factory sound systems
- Extremely powerful 64 Bit “fixed point” Audio DSP
- ACO – Advanced 32 Bit CoProcessor platform for extended feature set
- ISA (Input Signal Analyzer) and InputEQ for easy analysis and compensation of input signals
- DLC (Dynamic Loudness Control) and RTC (Remote Tone Control) for volume-dependent dynamic adjustment of highs and lows
- Proprietary TuneEQ function for automated adjustment of the input, virtual and output equalizers
- SFX (DSP Sound Effects) – Augmented Bass Processing, RealCenter & Co.
- Smart 4-channel highlevel input with ADEP.3 circuit
- 1:1 IOR (Input-to-Output Routing) – same number of highlevel inputs and amplifier outputs
- VCP (Virtual Channel Processing) allows even more flexible configuration for highly complex sound systems
- Optical input in SPDIF format with sampling rate between 12 and 96 kHz
- Mono RCA output for the connection of an external amplifier e.g. subwoofer amplifier
- SCP (Smart Control Port) for optional accessory like DIRECTOR, CONDUCTOR & Co.
- Auto Remote switch
- Start-Stop capable power supply with extended input voltage range up to 18 V – ideal for modern EV vehicles
- Compact design with low heat dissipation thanks to extraordinary efficiency
DSP features
TuneEQ
TuneEQ is an extremely flexible and particularly easy-to-use function for automated frequency response correction. A single measurement per audio channel or channel pair with a suitable measurement microphone (e.g. our MTK1) is sufficient for TuneEQ to independently and precisely adjust the equalizers to the desired reference curve. TuneEQ uses the full function set of the parametric equalizer including center frequency, Q-factor and gain adjustment. And since the highly complex arithmetic operations required for this run in the background, you also save a lot of time when optimizing your sound with TuneEQ.
RealCenter
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.
