Match M 5.4DSP miniature amplifier for powerful sound upgrades

The M 5.4DSP is barely larger than a smartphone. With 400/800W RMS/max output power and the latest DSP technology, it dramatically improves standard factory sound systems and brings genuine hi-fi performance into your car.

Performance and plug and play on demand

The M 5.4DSP offers two power modes: "HighPower" for maximum performance, or "MidPower" with reduced output and lower power consumption — allowing plug and play installation without a separate power supply cable.

The Match range includes a large number of pre-assembled adapter cables for straightforward plug and play connection, making it 100% upgradeable without leaving any traces.

Maximum flexibility

The 64-bit audio signal processor provides nine DSP channels. Four freely configurable RCA outputs allow connection of additional amplifiers, enabling complex, space-saving multi-channel systems. For dedicated bass, the Match UP 1FX mono subwoofer amplifier can be added via these outputs.

Features

• Ultra-efficient 5-channel amplifier with 4 line outputs and 9-channel DSP

• Plug and play installation without a separate power supply cable in "MidPower" mode
• "Fixed point" audio DSP with 64-bit resolution
• ACO (Advanced 32-bit CoProcessor) platform supporting system and DSP features including:
• ISA (Input Signal Analyzer) and InputEQ for analysis and compensation of input signals
• SFX sound effects: Augmented Bass Processing, StageXpander, RealCenter and more
• Optical input in SPDIF format with sampling rates between 12 and 96kHz
• Smart high-level input with ADEP.3 circuit and Auto Turn-On function
• VCP (Virtual Channel Processing) for flexible configuration of complex sound systems
• Auto Remote switch
• Start-Stop capability down to 6 volts supply voltage
• Freely configurable 4-channel line output for connection of additional amplifiers
• Subwoofer connection cable for Match plug and play and conventional subwoofers included
• SCP (Smart Control Port) for optional accessories including WIFI CONTROL, DIRECTOR, CONDUCTOR and more

Class GD technology

Audiotec Fischer's proprietary Class GD concept advances the efficiency of conventional Class D amplifiers by varying the internal supply voltage in several steps in response to the amplifier's input signals. This significantly reduces idle losses and keeps overall efficiency close to maximum at all times. Heat dissipation is almost negligible, allowing small heat sinks and a very compact form factor.

ACO: Advanced 32-bit CoProcessor

The M 5.4DSP incorporates a latest-generation 32-bit CoProcessor for all monitoring and communication tasks, internally and externally. Compared to the previous 8-bit generation, this MCU delivers much higher speeds for setup switching and data communication with the DSP PC-Tool software.

The CoProcessor's integrated native boot loader allows software upgrades across all DSP components — for example, to update the microcontroller-controlled ADEP.3 circuit in response to future changes in factory radio diagnostic systems, or when the device is extended with additional interfaces. The new flash memory also provides 10 memory locations for sound setups.

Start-Stop capability

The switched power supply in the M 5.4DSP maintains a constant internal supply voltage even if the battery voltage drops to 6 volts during engine crank.
