Marantz MM7055 review
Power For Your SystemThe MM7055 power amplifier produces 140 watts of high
current output from each of its five channels. This is “real world”
power, too, measured across the full audio bandwidth (20 Hz – 20 kHz) at
8 ohms with 0.08% Total Harmonic Distortion. Among other attributes, this
means the MM7055 is capable of long-term power delivery into low impedance
speakers.The Many Faces of ExcellenceIn practical terms, the MM7055 is
ideal for a “5.1” home theater system, whether based on a moderately
powered receiver or a surround sound processor. You can use it to power
speakers in different areas of your home; stereo reproduction in two rooms
plus a mono channel for secondary areas such as a den or kitchen. For
more complex home theater systems, the MM7055 pairs with one or several
MM7025s to help create a totally immersive “7.1” or “9.1” audio
experience.Inside The MM7055A massive power supply includes a
multiple-secondary EI-core transformer and over 65,000 µF of
custom-designed energy storage capacity. Critical circuit components from
many world-class suppliers were chosen only after extensive listening
tests. Among these, the LAPT Hyper Power output devices were first used
in Reference Series components. Current feedback topology insures
astounding accuracy and control under high-drive conditions.A
Temperature-Controlled EnvironmentPhysically, the MM7055’s output stages
mount on an extruded aluminum “thermal tunnel” for efficient heat
dissipation. With temperature-sensing forced air cooling, this
configuration assures cool operating temperatures for long-term
reliability, even when making full use of the amplifier’s substantial
output capabilities.Flexible ConnectionsBalanced inputs and single-ended
RCA inputs are both supported, and you can choose either type of input for
each channel, individually, for easy and flexible connectivity.
Audiophile grade, gold-plated four-way binding post speaker terminals
insure tight connections to your choice of speaker wire.Custom TouchesThe
MM7055 includes input and output jacks for DC “trigger” pulses as well
as RC-5 jacks for total remote control convenience, even with legacy
Marantz products.The chassis itself is heavy gauge steel for maximum
isolation from external vibration as well as electromagnetic and radio
frequency interference. And chassis depth is less than 14?” so the
MM7055 will fit quite nicely on a shelf, in a cabinet, or in a conventional
system rack with the optional rack mount kit RMK8003MM.Power.
Functionality. Dependability. And classic looks. The MM7055 is,
simply speaking, a Marantz.For operational and technical assistance 24/7,
