Class HD 2-channel micro amplifier, 2 x 170 WRMS @ 4 Ohm or 1 x 350 WRMS @ 2 Ohm

Excellent sound quality combined with maximum efficiency

The M 2.1AMP is the ultimate compact powerhouse for 1-channel or 2-channel applications where installation space is limited. Whether as a 2-ohm stable mono subwoofer amplifier or even as a particularly potent stereo amp for driving passive component systems or power-hungry woofers - this highly efficient powerhouse delivers up to 700W output power despite its minimalist dimensions. So much power in such a small space is made possible by Audiotec Fischer's proprietary Class HD technology, which guarantees sensational efficiency and therefore the lowest possible heat generation.

Power on demand

The switchable mono / stereo mode 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 even power-hungry front or rear speaker systems. Thanks to its high-res audio bandwidth, it also has the sound of a big player and leaves nothing to be desired.

Maximum flexibility in minimum space

In modern vehicles, the space available for sound upgrades is becoming increasingly limited and presents installers with major challenges, especially in multi-device setups. Thanks to their minimal dimensions, MATCH micro amplifiers such as the M 2.1AMP can be installed even in the most difficult of spaces. This opens up new, unimagined possibilities in the choice of installation locations and makes space-saving and concealed installation concepts feasible.

Features

  • Highly efficient Class HD power amplifier with mono / stereo mode
    • Mono mode: 1 x 350 watts RMS @ 2 ohms - ideal for driving powerful subwoofers with a voice coil
    • Stereo mode: 2 x 170 watts RMS @ 4 ohms - ideal for driving powerful front or rear speaker systems or a subwoofer with a dual voice coil
  • Excellent sound quality combined with maximum efficiency
  • Minimal dimensions for space-saving and concealed installation concepts
  • 2-channel RCA input
  • "Ground input" switch to avoid ground loops
  • Perfectly combinable with MATCH UPGRADE DSP amplifiers

Mono / stereo mode

The M 2.1AMP amplifier is equipped with a mono / stereo mode. This allows the amplifier to be configured as a 2-ohm mono amplifier or as a 4-ohm 2-channel amplifier, depending on the application. In both operating modes, the M2.1 AMP delivers an extended audio frequency response up to over 40 kHz for unrivalled sound quality thanks to its HiRes capability.

Class HD technology

The M 2.1AMP combines the advantages of Class H technology with the principle of a Class D amplifier. The result is an unrivalled efficiency that surpasses that of conventional Class D amplifiers. The Class HD concept shows its advantages at low and medium levels, as the power supply unit regulates the internal supply voltage of the power stages depending on the amplitude of the input signal. This drastically reduces the average power loss generated by the amplifier.

Start-stop capability

The power supply unit in the MATCH M 2.1AMP amplifier ensures the internal power supply even in the event of short-term dips down to 6 volts. This ensures that the M 2.1AMP remains fully functional even when the engine is started.
