Marantz MM7055 black

The classic-looking MM7055 amplifier produces 140W (8 ohms) of each of the five channels to fill the room with delicate sound. Ideal for a multichannel home cinema system or connect to speakers in different places in your home. Stereo reproduction is delivered to two rooms and plays a mono in the secondary area. If you want to extend your home cinema system, you can add the MM7025 and enjoy the 7.1 or 9.1 audio experience.

Key Features of the Marantz MM7055 Amplifier

• 5-channel amplifier in pure design
• Accurate and balanced tones in wide band
• Source for a massive energy flow
• Temperature stable even at high load
• Ideal for DTS Master Audio and Dolby TrueHD
• XLR and RCA inputs with different configurations
• Black design

Careful proposal

The MM7055 amplifier chassis is made of heavy duty steel for maximum insulation against vibration and electromagnetic and radio frequency interference. Amplifier power is based on a massive power supply with a multi-core EI core and capacitors capable of storing more than 65,000µF of energy. Critical circuit components are selected from many world suppliers to extensive testing. Here are the LAPT Hyper Power outputs from the Reference series for the first time. The feedback topology then provides tremendous accuracy and control over the signal even at high load.

Supplying any speakers

The 140W output is not just the theoretical number from laboratory conditions. You get full power across the bandwidth when outputting to 8 ohm speakers with 0.08% total harmonic distortion. The MM7055, however, is capable of transmitting sound to speakers with a low impedance (6 ohms) in the long run to accommodate various loudspeakers in a demanding listener's home.

Stable temperature

The output stages are mounted on the extruded aluminum into the so-called thermal tunnel in the MM7055 to ensure effective heat dissipation. The temperature sensor, if required, forces the cooling system to provide optimal operating temperatures. This ensures long-term reliability even with full potential utilization of the amplifier.
