Designed for the ultimate in audio music and surround movie experience, the Marantz MM8077 7-channel power amplifier delivers power and detail in the 150Watt at 8 ohm and 180Watt at 6 ohm. The power supply has a current transformer together with a high power capacitor filter (71WVDC) with a total capacity of 100,000μF for easy management of sharp short-term transient sound peaks. With the unique power supply function in all output channels, the MM8077 is equipped with multiple power transistors that have a wide operating range to play every detail of even the most demanding high-definition audio formats today. Aluminum double access heatsink, in tunnel arrangement, which provides both passive and active cooling. The mass coolers have multiple ridges that provide a large passive cooling area and the automatic fan is activated when the temperature rises to provide almost silent active cooling. For maximum connectivity, the MM8077 has asymmetric (RCA) and symmetric (XLR) inputs, and each channel of the amplifier can be configured to use the port of your choice. The speaker terminals are of Audiophile quality construction and are gilded for maximum signal transfer. The MM8077 has a DC (DC) power supply input and there is also a dual RC-5 remote control socket and connector for a compatible Marantz pre-amplifier/processor. The copper-plated chassis provides isolation from external noises. In elegant anodized black satin color, the MM8077 features the classic Marantz circular display with light blue color that includes on/off function.
