Match M 5.4DSP Installer-Package – 5-Channel Micro Amplifier with 9-Channel DSP
The M 5.4DSP belongs to the MATCH micro amplifier line from Audiotec Fischer. It combines four full-range channels, a dedicated subwoofer channel, four freely configurable line outputs and a 9-channel DSP in a housing of just 35 x 85 x 110 mm, making it suitable for stealth installations and for upgrading standard factory sound systems.
Installer Package – Scope of Delivery
This multi-unit installer package is aimed at professional installers and workshops who fit the same model in several vehicles. The package contains:
- 3 x MATCH micro amplifier M 5.4DSP
- 3 x Line Output-to-RCA cable
- 3 x Subwoofer cable 2-pole Molex for M 5.4DSP
- 3 x Remote connector for M 5.4DSP
Its key technologies are the proprietary Class GD amplifier concept, which varies the internal supply voltage in several steps according to the input signal to minimise idle losses and heat, the ACO 32-bit CoProcessor platform with Input Signal Analyzer, TuneEQ and SFX effects, and Virtual Channel Processing for complex OEM signal routing. Two power modes allow either maximum output or a reduced-consumption Plug & Play installation without a separate power cable.
Key Features
- Ultra-efficient 5-channel amplifier: Four main channels, one subwoofer channel, four line outputs and a 9-channel DSP.
- Two power modes: HighPower for maximum performance; MidPower with reduced output and consumption for Plug & Play installation without a separate power supply cable.
- Class GD technology: Multi-step supply voltage tracking keeps efficiency close to maximum, allowing very small heat sinks.
- 64-bit DSP: Fixed-point audio DSP with 64-bit resolution, 295 MHz (1.2 billion MAC operations per second).
- ACO 32-bit CoProcessor: Handles system and DSP functions including ISA, Input EQ and SFX effects, and provides 10 sound setup memories with fast switching.
- Smart high-level input: ADEP.3 circuit and Auto Turn-On.
- Optical SPDIF input: Accepts sampling rates from 12 to 96 kHz.
- Virtual Channel Processing (VCP): Multi-stage routing for complex factory systems.
- Configurable line outputs: Four freely configurable outputs for additional amplifiers, e.g. the MATCH M 2.1AMP.
- Smart Control Port (SCP): For optional controllers such as WIFI CONTROL, DIRECTOR or CONDUCTOR, powered via the port.
- Start-Stop capability: Operates down to 6 V supply voltage.
- Subwoofer cable included: PP-SOC cable for MATCH Plug & Play and conventional subwoofers.
Inputs & Outputs
- Inputs: 4 x high-level speaker input, 1 x optical SPDIF (12–96 kHz), 1 x remote in.
- High-level input: Sensitivity 5–11 V; input impedance 9–33 Ohms with ADEP.3.
- Outputs: 5 x speaker output, 4 x RCA line output (3 V), 1 x remote out (max. 500 mA).
- Auto Remote switch: Included.
Power & Amplifier Section
- Main channels: HighPower 4 x 60 W RMS @ 4 Ohms; MidPower 4 x 35 W RMS @ 4 Ohms (minimum load 3 Ohms in both modes).
- Subwoofer channel: 1 x 90 W @ 4 Ohms and 1 x 160 W @ 2 Ohms in both modes.
- Frequency response: 20 Hz – 20,000 Hz.
- Signal-to-noise ratio: more than 105 dB digital input, more than 99 dB analog input (A-weighted).
- Distortion (THD): less than 0.03 %; damping factor greater than 50.
- Idle current: 280 mA.
DSP & Sound Tuning
- Processing: 9-channel, 64-bit audio signal processor at 48 kHz sampling rate with BurrBrown A/D and D/A converters.
- ISA & Input EQ: Analyses and compensates the input signals of modern head units channel by channel.
- TuneEQ: Automated frequency response correction – one measurement per channel or channel pair with a measurement microphone such as the MTK1 sets centre frequency, Q and gain of the parametric EQ to a reference curve.
- RealCenter: Generates a centre signal only from content present in both front channels, dynamically controlled by the stereo content, for a wider stage for driver and passenger.
- Augmented Bass Processing: Dynamic Bass Enhancement raises the low range and shifts the subsonic cutoff with the signal for more bass at low and medium volume without overloading the sub; the optional SubXpander adds subharmonics to fundamentals between 50 and 100 Hz.
- Further SFX: StageXpander among other effects.
- Software: Configured with the DSP PC-Tool via USB.
Installation & Connectivity Notes
- Operating voltage: 10.5–17 V, max. 5 s down to 6 V.
- Power rating and fuse: DC 12 V, 40 A max.; 1 x 30 A fuse.
- Operating temperature: -40 °C to +70 °C.
- Dimensions (H x W x D): 35 x 85 x 110 mm.
- Integration: MATCH pre-assembled adapter cables allow trace-free Plug & Play connection to the factory system.
