The MISCO MA-2002 two-channel amplifier offers both line-level and speaker-level inputs for maximum source flexibility. Need to bring in audio from a speaker-level source like a TV? No problem, the MA-2002 has you covered. Both low level and high level inputs have trim pots to adjust input gain. This versatile amp also provides high-pass, low-pass, and all-pass filters, easily adjustable by jumpers on the PCB.  It accepts a power supply input range of 18 to 24 volts allowing you to use existing power rails or an external MISCO power supply (sold separately). The MA-2002’s cool-running Class D circuitry delivers up to 25 Watts per Channel* for high dynamic range output, perfect for noisy environments. 

Key Features

  • Up to 25 Watts x 2 output*
  • Cool running, reliable Class D operation
  • Versatile 18 – 24VDC input power range
  • Trim-able speaker and line level inputs
  • Jumper-selectable high, low, and all-pass filters

*Power output varies with supply voltage and speaker impedance. See specs table for details.
