Match 2-Channel Amplifier

*Special Order* Owner's Manual

Excellent sound quality combined with maximum efficiency

The M 2.1AMP is the ultimate compact powerhouse for 1-channel or 2-channel applications with limited installation space. Whether as a 2 Ohms stable mono subwoofer amplifier or even as a particularly potent stereo amp for driving passive component systems or power-hungry woofers – despite its minimalist dimensions this highly efficient performer delivers up to 700 W output power. These amazing figures in such a tiny space result from Audiotec Fischers proprietary Class HD-technology, which guarantees an unrivaled efficiency and therefore minimum heat dissipation. 

Power on demand

The switchable mono / stereo operation makes the M 2.1AMP a multifunctional tool.
In mono mode, it is ideal for driving powerful subwoofers with a minimum impedance of 2 Ohms – in stereo mode, it is the perfect choice for driving powerful front or rear speaker systems.
Thanks to its High-Res audio bandwidth the M 2.1AMP is a giant in sound performance and leaves nothing to be desired.

Maximum flexibility 
in a minimum of space

In modern vehicles, the space available for sound upgrades is becoming increasingly limited and presents new challenges to installers especially with multi-device setups.Thanks to their minimal dimensions, MATCH micro amplifiers like the M 2.1 AMP can be mounted even in the most difficult space conditions and open up new, unimagined possibilities in the choice of installation location and therefore allow stealth installation concepts.


  • Ultra efficient Class HD amplifier with exceptional power-to-size ratio
  • Mono Mode: 1 x 350 Watts RMS @ 2 Ohms – Perfect to run powerful subwoofers with 2 Ohms single voice coil (SVC2) or 4 Ohms dual voice-coil (DVC4)
  • Stereo Mode: 2 x 170 Watts RMS @ 4 Ohms – Perfect to run powerful front / rear speaker systems or powerful front / under-seat subwoofers with 4 Ohms single voice coil (SVC4)
  • Small size for hidden installation concepts
  • Excellent sound quality combined with a max. signal-to-noise ratio of 108 dB and a THD of < 0.02 %
  • 2-channel RCA / Cinch input
  • “Ground Input” switch to avoid ground loops
  • Perfect combination with MATCH UPGRADE DSP amplifiers

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 which 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.
