Designed for the ultimate music and movie surround sound experience, the 7-channel MM8077 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 filter capacitors that provide substantial headroom for dynamic peaks along with the ability to handle lower impedance speaker loads. All output stages feature identical topology for uniform high-quality sound across all channels, and the MM8077 lets you choose between balanced (XLR) and unbalanced (RCA) inputs for each channel, for maximum system configuration flexibility. The amp is equipped with multiple high current, high bandwidth discrete power transistors with a high slew rate, which extracts the most detail from today's high-resolution audio formats. Pair the MM8077 with MM7705 5-channel power amplifier to enjoy thrilling 11 channel surround sound with the latest multi-channel audio formats, such as DTS Neo:X. For easy control, the MM8077 features remote power on/off control compatibility with select Marantz A/V pre-amplifiers, such as AV8801.

High-Grade Components for Dynamic Surround Sound With its reference-class components, the MM8077 Power Amplifier can play back the most dynamic movie soundtracks and music with precise, pristine fidelity. The amplifier's high-capacity power supply capacitors and massive toroidal transformer enable it to track rapid sonic changes--such as sudden volume spikes and bass influxes--with greater precision than an ordinary amplifier. In addition, all output stages feature an identical topology, which ensures high-quality audio across every channel. The result is seamless, natural audio performance that remains free of distortion even when you max out the volume.
For an even more dynamic and full-bodied soundstage, you can couple the MM8077 with a 5-channel amplifier (such as the ) to experience thrilling, 11.2-channel surround sound.
Versatile Power Supply Supports Low-Impedance Speakers Rated at 150 watts per 7 channels, the MM8077 provides enough power and stability to support a wide range of speaker setups. The amplifier's power supply features a massive toroidal transformer, designed to withstand short-term bursts of current. This makes the amplifier safe for use with lower-impedance speakers, since its output stage is protected against sudden power peaks. The toroidal transformer also produces minimal electromagnetic interference, helping the amplifier operate with very low distortion.
Durable Design with Copper-Plated Chassis The MM8077 features a sleek black finish that will seamlessly blend with your home theater system and has a blue-illuminated lighting accent around the unique porthole display. Its chassis is plated with copper, which guards the amp's components against external interference.
