Marantz MM7055 5 Channel Power Amplifier Black
Ideal forHome Theater or Distributed Audio
From itssculptured front panel to its high quality binding-post loudspeaker terminals,the MM7055 five channel power amplifier brings Marantz sound quality tovirtually any music or home theater system. Using technologies originallydeveloped for the exclusive Marantz Reference Series, this flexible amplifierboasts many possible uses. For example, the MM7055 is ideal for a 5.1 hometheater system. You can use it to power speakers in different areas of yourhome; stereo reproduction in two rooms plus a mono channel for secondary areassuch as a den or kitchen. For more complex home theater systems, the MM7055pairs with one or several MM7025s to help create a totally immersive “7.1” or“9.1” audio experience. The MM7055 produces 140 watts of high current outputfrom each of its five channels. This is “real world” power measured across thefull audio bandwidth (20 Hz – 20 kHz) at 8 ohms with 0.08% Total HarmonicDistortion. Among other attributes, this means the MM7055 is capable oflong-term power delivery into low impedance speakers.
Inside theMM7055
A massivepower supply includes a multiple-secondary EI-core transformer and over 65,000µF of custom-designed energy storage capacity. Critical circuit components frommany world-class suppliers were chosen only after extensive listening tests. Amongthese, the LAPT Hyper Power output devices were first used in Reference Seriescomponents. Current response topology insures astounding accuracy and controlunder high-drive conditions. Physically, the MM7055’s output stages mount on anextruded aluminum “thermal tunnel” for efficient heat dissipation. Withtemperature-sensing forced air cooling, this configuration assures cooloperating temperatures for long-term reliability, even when making full use ofthe amplifier’s substantial output capabilities.
Balancedand Unbalanced Connections
Balancedinputs and single-ended RCA inputs are both supported, and you can chooseeither type of input for each channel, individually, for easy and flexibleconnectivity. Audiophile grade, gold-plated four-way binding post speakerterminals insure tight connections to your choice of speaker wire. The MM7055includes input and output jacks for DC “trigger” pulses as well as RC-5 jacksfor total remote control convenience, even with legacy Marantz products. Thechassis itself is heavy gauge steel for maximum isolation from externalvibration as well as electromagnetic and radio frequency interference. Andchassis depth is less than 14-1/2” (without connectors) so the MM7055 will fitquite nicely on a shelf, in a cabinet, or in a conventional system rack with anoptional rack mount kit.
