Match M 2FX 2 Channel Class GD Comapct Amplifier 440w RMS
MATCH M 2FX - 2-channel Class GD miniature amplifier
Tiny amplifier with big ambitions – the M 2FX combines the smallest dimensions with huge power and the highest versatility.
Equipped with an active crossover with high- or low-pass, stereo line input and high-level inputs with an ADEP circuit as well as further top-notch features, this ultra-compact two-channel amplifier perfectly acts as a stand-alone amplifier for demanding speaker systems or as a power source for subwoofer applications. Due to its load stability, the M 2FX is almost predestined for driving subwoofers with 2 x 2 Ohms impedance.
The proprietary Class GD technology combines excellent sound quality with extraordinary high efficiency. Thanks to its minimal dimensions and low heat dissipation, unprecedented space-saving and hidden installation concepts can be realized that were previously impossible.
In combination with the five-channel amplifier M 5DSP from the MATCH portfolio, the M 2FX is literally a “perfect MATCH”.

Class GD amplifier technology
Audiotec Fischer's unique Class GD concept combines the advantages of Class G technology with the principles of a Class D amplifier. This results in an exceptionally high efficiency, surpassing even conventional Class D amplifiers. The Class GD concept demonstrates its advantages at low and medium output levels by varying the internal supply voltage of the power stages depending on the amplitude of the input signal. The minimized power dissipation allows for extremely compact amplifier dimensions and thus space-saving and concealed installation designs, previously impossible.
Intelligent high-level input
Modern, factory-installed car radios are becoming increasingly intelligent in diagnosing the connected speakers. If an amplifier is connected to the radio instead, error messages often occur, sometimes even resulting in the loss of certain functions (such as the fader). The new ADEP (Advanced Diagnostics Error Protection) circuit prevents all these problems without unnecessarily straining the radio's speaker outputs at high volume levels.
Start-stop capability
The power supply in the MATCH M 2FX amplifier ensures a stable internal voltage supply even during brief dips down to 6 volts. This guarantees that the MATCH M 2FX remains fully functional even when the engine is started.
Special features:
Mono/Stereo mode
The M 2.1AMP amplifier is equipped with a mono/stereo mode. This enables the amplifier to be configured as a 2-ohm-capable mono amplifier or as a 4-ohm-capable 2-channel amplifier, depending on the application. In both operating modes, the M2.1 AMP delivers, thanks to its HiRes capability, an extended audio frequency response of over 40 kHz for unsurpassed sound quality.
Class HD technology
The M 2.1AMP combines the advantages of a Class H technology with the principle of a class D amplifier. The result is an unsurpassed efficiency that easily outperforms any conventional Class D amplifier. By varying the internal supply voltage depending on the amplifier’s amplitude of the input signals, idle losses are significantly reduced and overall efficiency is close to maximum at any time.
Start-Stop capability
The switched power supply of the MATCH M 2.1AMP assures a constant internal supply voltage even if the battery’s voltage drops to 6 Volts during engine crank.
