The Marantz MM7025 is an amazing 2-channel power amplifier that pumps out 140W of power. It has a great industrial design and a high-capacity power supply. This amplifier features the same LAPT Hyper-Power output transistors as the Marantz Reference Series. The high-capacity power supply comes with an oversized EI-core transformer and over 30,000 μF of energy storage capacity. Its output stages are mounted on an extruded aluminum 'thermal tunnel' for effective heat dissipation. It offers 2 balanced XLR inputs and 2 single-ended RCA inputs, allowing you to choose the input type for each channel. Technical specs include a power output of 140W (20Hz - 20kHz, 0.08%), 2-channel balanced and unbalanced input, 2 binding post speaker terminals, a frequency response of 8Hz - 100kHz (+/- 3dB), a signal-to-noise ratio of 105dB, dimensions of 17.36 x 13.88 x 4.93' / 441 x 353 x 125 mm, and a weight of 23.8 lb / 10.8 kg.
Using the Marantz MM7025 power amplifier is easy. First, connect your speakers to the 2 binding post speaker terminals. Then, choose between the balanced XLR inputs or single-ended RCA inputs for each channel using the selector switch. Plug in the amplifier and turn it on. When using, keep it in a well - ventilated area to help with heat dissipation as it has an extruded aluminum 'thermal tunnel' for this purpose. Avoid placing it near sources of strong heat or moisture. For maintenance, periodically clean the exterior with a soft, dry cloth. Check the connections regularly to make sure they are secure. If you notice any unusual noises or performance issues, turn off the amplifier and consult the Marantz support team.
