Marantz MM8077 7-Ch Power Amplifier

Description

Designed for the ultimate music
and movie surround sound experience, the Marantz MM8077 7-channel power
amplifier delivers power and detail, and is rated at 150 watts per channel into
8 ohms, and 180 watts per channel into 6 ohms.

The power supply features a high
current toroidal power transformer along with high power (71WVDC) filter
capacitors with a total 100,000µF capacitance to easily handle sharp short-term
transient peaks.

Featuring our unique current
feedback discrete power amp output stages that are identical for all channels,
the MM8077 is equipped with multiple high current discrete power transistors
that feature high slew rate and wide operating bandwidth to extract the most
detail from today’s high resolution audio formats.

The output devices are mounted
on our unique dual extruded aluminum alloy heat sink assembly, configured in a
tunnel arrangement that provides both passive and active cooling. The massive
heat sinks feature multiple ribbed fins that provide a large passive cooling
area, and the assembly is book-ended with a whisper quiet fan that
automatically kicks in to provide near silent active cooling when the
soundtrack heats up. As the fan is mounted internally directly to the heat
sinks, and not externally to the chassis cover as is often the case, even when
it’s running, it’s designed to be whisper quiet.

For maximum connectivity, the
MM8077 features both unbalanced (RCA) and balanced (XLR) inputs, and each amp
channel can be configured to use your choice of input connector. The
loudspeaker terminals feature audiophile-grade construction, and are
gold-plated for maximum signal transfer, and they can easily handle a wide
range of audiophile speaker cable connectors.

The MM8077 features a DC trigger
input for external power on/off control, and there’s also dual RC-5 remote
control in/out jacks for connection to a compatible Marantz A/V pre-amp/processor.

The copper-plated chassis provides isolation
from extraneous noise, and features a multi-layer reinforced bottom panel
assembly for maximum rigidity along with triple-layer top cover. Elegantly
finished in anodized black satin, the MM8077 features the classic Marantz
ringed porthole display with a blue illumination accent that includes a display
on/off function.
