Miniature amplifier for powerful sound upgrades
The new M 5.4DSP is a true giant in terms of power, while being barely larger than a smartphone. With incredible 400/ 800 Watts RMS/ Max. output power and the latest DSP technology, it dramatically improves every standard sound system and brings real hifi sound into your car.
Ultra-compact installation
In modern vehicles, the space available for sound upgrades is becoming increasingly limited and presents new challenges to installers. Thanks to its minimal dimensions, the M 5.4DSP can be mounted even in the most difficult space conditions and opens up new, unimagined possibilities in the choice of installation location.
In addition, the all-new Smart Control Port (SCP) offers a significantly more space-saving connection due to its extremely compact and securely locking connector. Via the SCP, all Audiotec Fischer remote controls – such as CONDUCTOR or URC.3 – can be connected and easily placed even in the smallest installation positions. In addition, the new Smart Control Port (SCP) offers a significantly more space-saving connection thanks to its extremely compact, securely locking connector.  A direct power supply to the controller via the SCP is also possible, which makes an additional power cable unnecessary and simplifies installation even more.
Performance & real Plug & Play on demand
The M 5.4DSP features two power modes, allowing it to run either in “HighPower” mode for maximum performance or in “MidPower” mode with reduced output power and lower power consumption for Plug & Play applications without a separate power supply cable.
The MATCH range of accessories offers a large number of pre-assembled adapter cables for simple plug & play connection – and is therefore 100% upgradeable without leaving any traces.
Maximum flexibility
The extremely powerful 64 Bit audio signal processor offers nine DSP channels. Four freely configurable RCA outputs allow the connection of additional amplifiers, such as the MATCH M 2.1AMP amplifier. This enables complex and space-saving multi-channel systems with enormous performance.
Virtual Channel Processing – the new era of signal routing
To handle the mass of DSP channels and configure them in a user-friendly way the M 5.4DSP is equipped with Audiotec Fischer's innovative Virtual Channel Processing. Modern factory sound systems with an increasing number of inputs have a significant impact on the complexity of the signal routing inside the amplifier. Especially when several input signals are first mixed and afterwards split again into multi-way systems, conventional routing concepts quickly reach their limits.  Audiotec Fischer's new multi-stage "Virtual Channel Processing", in conjunction with the well-known and user-friendly DSP PC-Tool software, makes highly complex system configurations look easy. On top, it allows to freely assign our proprietary FX sound features such as "RealCenter" or "Augmented Bass Processing".
ACO – Advanced 32 Bit CoProcessor platform
The M 5.4DSP features the extremely powerful 32 Bit ACO platform. It takes care of all control tasks and is faster than traditional systems, especially in data communication with our DSP PC-Tool software. The ACO Platform even introduces lightning-fast switching between up to 10 sound setups. But ACO offers much more – fantastic sound effects such as Augmented Bass Processing or RealCenter are easy ways to maximize the sound experience. Additionally, the channel-separated Input EQ including the Input Signal Analyzer (ISA) allows easy analysis and compensation of input signals provided by modern radios and head units.
