Product Overview

The Match M 5.4DSP is the flagship micro amplifier from the Match M Series, delivering enormous performance and DSP sophistication in a housing barely larger than a smartphone at 35 x 85 x 110mm. Designed for stealth installation concepts in modern vehicles where space is severely limited, the M 5.4DSP opens up installation possibilities that conventional amplifiers cannot achieve, including behind dashboards, under seats, inside door panels, and in other confined spaces.

The Class GD topology delivers four full-range speaker channels plus a dedicated subwoofer output channel, with two operating modes: HighPower mode delivers 4 x 60W RMS at 4Ω (minimum 3Ω) and 1 x 90W RMS at 4Ω (160W at 2Ω) subwoofer output for maximum performance installations with a dedicated power supply cable. MidPower mode delivers 4 x 35W RMS at 4Ω with the same subwoofer output for true plug-and-play installations without a separate power supply cable, enabling clean upgrade paths in vehicles where running a new power cable is impractical.

The 4 high-level ADEP.3 inputs (5-11V, 9-33Ω with ADEP.3) and optical SPDIF input (12-96kHz) cover all OEM integration scenarios. Four freely configurable RCA outputs at 3V enable the connection of additional external amplifiers for multi-amplifier system architectures. The 9-channel DSP runs on a 64-bit fixed-point processor at 295 MHz (1.2 billion MAC operations per second) with BurrBrown A/D and D/A converters, 48kHz sampling rate, SNR above 105dB from digital input and above 99dB from analog input, and THD below 0.03%. The ACO 32-bit CoProcessor manages ISA with InputEQ, TuneEQ, VCP, RealCenter, Augmented Bass Processing, StageXpander, DLC, and RTC with up to 10 sound setup memories. Operating voltage is 10.5-17V with Start-Stop capability to 6V. Fused at 1 x 30A Maxi (APX).

Features & Benefits

Ultra-Compact 35 x 85 x 110mm - Micro Amplifier for Stealth Installations: The M 5.4DSP packs 5 amplifier channels, 9 DSP channels, 4 high-level inputs, optical SPDIF, and 4 RCA outputs into a 35 x 85 x 110mm housing, enabling installation in locations impossible for conventional amplifiers including behind dashboards, inside door cavities, and under seats in modern vehicles with extremely limited space.

Dual HighPower/MidPower Operating Modes: HighPower mode delivers 4 x 60W RMS at 4Ω for maximum performance with a dedicated power supply cable. MidPower mode delivers 4 x 35W RMS at 4Ω with identical subwoofer output for true plug-and-play installation without a separate power supply cable, enabling completely trace-free sound upgrades using Match's pre-assembled adapter cable range.

Class GD Technology - Maximum Efficiency with Minimal Heat Dissipation: Class GD varies the internal supply voltage in multiple steps depending on the amplifier's input signal, reducing idle losses and maintaining efficiency close to maximum at all times. Heat dissipation is almost negligible, enabling the smallest possible heatsinks and most compact form factors - a prerequisite for the M 5.4DSP's micro dimensions.

9-Channel Integrated DSP - 64-Bit Fixed-Point at 295 MHz: The 9-channel DSP delivers 64-bit fixed-point processing at 295 MHz (1.2 billion MAC operations per second) for complex multi-channel equalisation, crossover, time alignment, and sound effect processing with exceptional precision from a micro-sized unit.

4 High-Level ADEP.3 Inputs with Auto Turn-On - Seamless OEM Integration: The 4 high-level ADEP.3 inputs (5-11V) with built-in Auto Turn-On function connect directly to the factory speaker outputs without requiring a separate remote wire, providing seamless plug-and-play OEM integration without triggering factory head unit error messages.

4 Freely Configurable RCA Outputs for Multi-Amplifier Expansion: Four configurable 3V RCA outputs allow the connection of additional external amplifiers such as the Match M 2.1AMP, enabling complex multi-channel system architectures from the M 5.4DSP as the central DSP hub without requiring a separate DSP processor unit.

ACO 32-Bit CoProcessor - ISA, TuneEQ, VCP, RealCenter, Augmented Bass Processing, StageXpander: The ACO platform provides ISA with InputEQ for OEM signal analysis and correction, TuneEQ automated parametric EQ calibration, VCP cross-channel group equalizers, RealCenter dynamic center image synthesis, Augmented Bass Processing (Dynamic Bass Enhancement and SubXpander), StageXpander for enhanced stereo imaging, and up to 10 sound setup memories with instant switching.

SCP Smart Control Port - Compact Direct-Power Connection: The SCP (Smart Control Port) accepts optional remote controls including Match CONDUCTOR, DIRECTOR, and WIFI CONTROL accessories with a compact, securely locking connector. Direct power supply to the connected controller via the SCP eliminates the need for a separate power cable to the remote control.

VCP - Virtual Channel Processing for Complex Multi-Input Systems: VCP handles the complexity of modern factory multi-channel sound systems by providing cross-channel group equalizers and free assignment of DSP Sound Effects across all 9 DSP channels, enabling highly complex mixed input and multi-way output configurations in a user-friendly workflow.

Optical SPDIF Input (12-96kHz): Accepts digital optical signals from compatible source units for interference-free, ground-isolated signal transmission into the DSP.

Start-Stop Capable - 10.5-17V Extended Operating Range: Start-Stop capable power supply maintains stable operation during voltage drops to 6V and supports an extended operating voltage up to 17V for modern EV and mild hybrid platforms.

Frequently Asked Questions

What is the difference between HighPower and MidPower mode on the M 5.4DSP?

HighPower mode delivers 4 x 60W RMS at 4Ω with maximum performance, requiring a dedicated power supply cable connection. MidPower mode delivers 4 x 35W RMS at 4Ω with reduced output power and lower power consumption, enabling true plug-and-play installation without a separate power cable using Match pre-assembled adapter harnesses. The subwoofer output delivers identical power (90W at 4Ω, 160W at 2Ω) in both modes.

Does the M 5.4DSP have RCA inputs?

No. The M 5.4DSP uses high-level ADEP.3 inputs only for signal input, with no RCA line-level inputs. Signal is accepted via the 4 high-level inputs or the optical SPDIF input. Four RCA outputs are provided for connecting additional external amplifiers.

What remote controls are compatible with the M 5.4DSP SCP port?

The SCP Smart Control Port is compatible with Match CONDUCTOR, Match DIRECTOR, Match WIFI CONTROL, and other Audiotec Fischer SCP accessories. All SCP accessories are sold separately. The SCP can also provide direct power to the connected controller, eliminating the need for a separate controller power cable.

Can the M 5.4DSP be installed without running new wiring in the vehicle?

Yes. In MidPower mode, the M 5.4DSP can be installed without a separate power supply cable using Match pre-assembled adapter harnesses (sold separately), enabling a completely trace-free plug-and-play sound upgrade that is fully reversible.

What is StageXpander on the M 5.4DSP?

StageXpander is an Audiotec Fischer DSP Sound Effect that enhances the perceived stereo image width and depth, creating a broader and more immersive soundstage in the vehicle acoustic environment.
