The Marantz MM7055 is a top - notch 5 - channel power amplifier, ideal for a 5.1 home theater setup. Each of its 5 channels can pump out 140W of power. It has a massive power supply with a multiple - secondary EI - core transformer and over 65,000 μF of custom - designed energy storage. The output stages are on an extruded aluminum 'thermal tunnel' for great heat dissipation. You can choose between 5 balanced XLR inputs and 5 single - ended RCA inputs for each channel. And it comes with audiophile - grade, gold - plated four - way binding post speaker terminals. Tech specs include 140W power output (20Hz - 20kHz, 0.08%), 5 - channel balanced and unbalanced inputs, 5 binding post speaker terminals, 8Hz - 100kHz frequency response, 105dB signal - to - noise ratio, dimensions of 17.19 x 15.12 x 7.19 inches (437 x 384 x 183 mm) without antenna, and a weight of 34.6 lb (15.7 kg).
Using the Marantz MM7055 power amplifier is a breeze. First, connect your speakers to the 5 binding post speaker terminals. You can pick either the balanced XLR inputs or single - ended RCA inputs for each channel based on your setup. Just use the selector switch to choose. Then, plug it into a power source. When using it, make sure there's enough space around the amplifier for proper ventilation because of the 'thermal tunnel' heat - dissipation design. Keep it away from moisture and dust. For maintenance, gently wipe the exterior with a dry cloth from time to time. Don't touch the internal components yourself as it can be dangerous. If you have any problems, contact Marantz support.
