Marantz MM7025 Stereo Power Amplifier (Black)

The MM7025 is equipped with a current feedback circuit and uses the same complimentary push-pull circuit as the far more expensive SM-11S1 power amp, providing minimal phase shift and excellent detail resolution. The current/voltage conversion section has a Wilson current mirror circuit to improve circuit stability and high-speed processing.

Product Highlights:

  • 140 watts per channel into 8 ohms (20-20,000 Hz) at 0.08% THD with 2 channels driven
  • 170 watts per channel into 6 ohms
  • Frequency response: 8-100,000 Hz (±3 dB)
  • Signal-to-noise ratio: 105 dB
  • Discrete Current Feedback circuit for accurate, natural sound at all volume levels
  • Oversized power transformer for high current levels
  • One RCA and one XLR input for each channel
  • DC trigger input/output
  • IR flasher input
  • Gold-plated binding post speaker terminals
  • Detachable power cord

  • Weight: 23.8 lbs.
  • Warranty: 3 years
  • Our 30-day money-back guarantee
  • MFR # MM7025

Instant Power Supply: The final stage of the power amp uses the same LAPT (high efficiency power transistor) as the SM-11S1, offering instant power supply capability. The power section has a large transformer and Marantz original 15,000 μF / 71 V x 2 block condensers to provide a powerful, presence filled sound.

Heat Dissipation: The chimney-shaped heat sink efficiently processes the heat emitted from each side of the amp and a quiet cooling fan removes the heat from the chassis. A high-sensitivity temperature sensor IC is used to control the cooling fan's rotation speed to match the amount of heat generated by the amp.

Auto Standby: With the Auto Standby Mode is turned on this unit will enter standby mode after approximately 30 minutes (continuous) with no input signal.

Speaker Outputs: The speaker output terminals are binding posts; they are not 5-way posts, but will accept single banana plugs, pin connectors, and bare wire. A plastic collar prevents their use with spade lugs and they're too far apart for dual banana plugs.

Inputs: There are RCA (unbalanced) and XLR (balanced) inputs. Separate switches for the left and right channels specify which is engaged; useful if you're not using the MM7025 as a stereo amp.

Display: A blue indicator on the front panel display and a blue ring around the display light when the power is on; the blue ring around the display can be turned off if you prefer. Separate red indicators on the display light when the protection circuit or Auto Standby feature is engaged.

Remote Power Control: This unit is equipped with a remote power control function; when a compatible Marantz preamp is connected, this unit's power can be switched on and off simultaneously with the preamp. The RCA Remote Control input is connected to the preamp and the Remote Control output can be connected to other compatible Marantz components; CD player, DVD player, Tuner, etc.

Flasher Input: The IR flasher input is useful with universal remote controls; power and mute remote codes are available for the MM7025.

DC Control: The 3.5mm mini-jack input allows the MM7025's power to be controlled by another device (5-15 V). The DC Control output allows the MM7025 to control the power of another compatible device (12 V/44 mA).
