Our flagship product, the D-Sonic M3a-5400-7 represents the sonic state of the art in multi-channel amplifier design. Featuring the most powerful high fidelity Class D modules on the planet fed by a best-in-class proprietary input circuit, the M3a-5400-7 is an extremely powerful home theater amplifier. Audiophiles can enjoy 1500W of power for their left and right channels with vanishingly low distortion, iron-tight bass control and realistic soundstage. The center channel receives a separate 800W power supply, while each surround speaker gets 400W of dedicated power.


  • M3 Multichannel units are designed to distribute the power proportionally to the various channels. The front right and left require the dominant share (70% average) of all of the output for 5.1 and 7.1 channel performance. Some customers believe the center channel should have this higher power also. We offer both options.
  • Any combination, including full power in all channels, is available in our CUSTOM SERIES (see Amplifier categories).
  • All 3-7channel units have 12VDC trigger circuits to allow standby, low energy dissipation when not in use.
  • Manual, front panel shutoff is standard for ultimate safety and zero energy loss. 
  • All cords are 20A and use a standard or dedicated wall plug.
  • Optional: Second fuse and power cord for commercial applications of the M3-5400-7 to handle any potential current demand. $245.00
  • Dimensions: 17.5”W x 18.5”D x 5.0”H. Add .63″ to height for standard feet, .25″ for rack mount feet.
