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.

Item Condition
Item Condition
Buying a Marantz Factory Refurbished product is a great way to get "as-new" products at a considerable savings. Every product has been thoroughly tested, repaired (if necessary), cleaned and otherwise renewed to original condition. Next it's repackaged with original accessories included. When you consider that a factory-renewed Marantz product undergoes such close scrutiny for defects and workmanship, you might actually be buying something that is in many ways better than new. And for your piece of mind and protection, your purchase is covered by a full 1 year parts and labor warranty valid at any authorized Marantz repair center (you can look-up locations online here or call 800-654-6633)
Marantz, like all electronics manufactures, receives products returned for various reasons. In 2011 consumers returned 17 billion dollars in electronics globally, of which less than 5% were found to be defective! Once a product has been opened, it must be resold as refurbished or open box and can't be resold as new again. The history and reason why a product was returned is not provided to us, thus we can't provide any additional details regarding its past. All products are processed by Marantz certified technicians, where they are fully tested, repaired (only if necessary), and retested again to ensure the highest quality control. Each unit must pass a complete battery of test before it can be titled a "Marantz Factory Refurbished" product.
Most units are Cosmetically in Mint Condition (graded a 9 or higher on a scale of 1-10). Very minor signs of wear (light surface scuffs or minor scratches) may be present, although most units show little or no signs of any usage. We DO NOT sell products that are cosmetically damaged (cracked displays, broken knobs, heavy scratches, or physically abused) unless noted in the description. Unfortunately, we can't provide actual photos of each unit or pick the best one for anyone, as they are all randomly chosen from our factory sealed boxes.

Quiet, good power
Of course, the transaction and communication from Accessories4less was superb, and I will buy from them again without any hesitation.
