1120W, 8 channels . . . oh, the possibilities

These days, home theater is a lot more than a TV, a DVD player, and a couple of speakers. A whole lot more. For starters, in order to take full advantage of the 7.1-channel, studio-quality surround sound available on Blu-ray Disc, you've gone and invested in a 7.1-channel speaker constellation for your home theater. Now, because you believe in a cinema-sized home theater experience, you've chosen large, two- and three-way floorstanding and bookshelf speakers for your home theater. Sure, A/V receiver/amp combo units deliver power and connectivity, but to truly experience your surround sound system's potential, you need serious power. Enter the MM8003 power amplifier from Marantz. Serving up a full eight channels of output power at a whopping 140W each, the MM8003 lets you effortlessly power seven surround channels as well as an in-wall subwoofer. And although the MM8003 operates great as a stand-alone amplifier, it is specifically designed to complement the Marantz AV8003 preamp/processor.

Possibilities, remember?

We began by pointing out that the modern home theater has expanded beyond the simple pairing of a TV and a video source. Well, so too has it grown beyond a single room. While you can choose to power a 7.1-channel system in the living room with the MM8003, you also have the option of powering four individual stereo zones. Imagine: you can power a pair of speakers in the kitchen, the garage, the bedroom, and the foyer, all with a single component, and all with 140W of power per channel!

A little something for the die-hards

Despite the MM8003's relatively simple home-theater application, this power amp is an impressively sophisticated piece of equipment. This is another way of saying that it's now time to indulge those home-audio enthusiasts among you who can only be convinced by the nitty-gritty details. Here we go: Unlike some amplification devices that report output power only at specific frequency levels, the MM8003 ensures 140W per channel across the full bandwidth spectrum (20Hz - 20kHz) at 8-ohms impedance and with less than 0.08% total harmonic distortion. Further, the MM8003 guarantees clean, high-fidelity power output thanks to a variety of design features, including a multiple secondary torodial transformer and custom-designed capacitors mounted in copper-plated, anti-vibration brackets. While critical circuit components were chosen from WIMA and other world-class suppliers only after extensive auditory evaluation, current feedback topology ensures astounding accuracy and control even under high-drive conditions. Finally, the MM8003's output stages are mounted on an extruded-aluminum "thermal tunnel" for efficient heat dissipation. With four cooling channels on each side of the tunnel and temperature-sensing forced-air cooling, this configuration ensures extended dependability. And "dependability" is just another word for "high-fidelity".

External dependability

While the design and construction of the MM8003's internal components ensures high-fidelity audio performance, the same can be said of this power amp's external chassis design. Constructed of heavy-gauge, copper-plated steel, the MM8003's chassis delivers maximum isolation from external vibration as well as from electromagnetic and radio-frequency interference. Additionally, audiophile-grade, gold-plated speaker outputs deliver secure, highly conductive connections for your chosen speaker wire.
