Marantz AMP 20

The Marantz AMP 20 is a true powerhouse for those who want to take their home theater to the next level. This 12-channel power amplifier delivers 200 watts per channel at 8 ohms, offering a combination of raw power, finesse, and that classic Marantz feel that makes everything just sound right—whether it’s an intense action movie or a concert recording.

With patented HDAM-SA2 circuits, custom-developed Class D amplification, and Sound Master tuning, you get exceptional dynamics, low distortion, and a warm, engaging sound character that pairs perfectly with the Marantz AV 20 or other processors in the series. Everything is made in Shirakawa, Japan, featuring a copper-plated chassis, solid metal front, and the iconic porthole with VU meters that display power in real time.

Want ultimate control and headroom? The AMP 20 handles large Atmos and DTS:X setups without breaking a sweat. You get twelve channels in a single chassis, ready for bi-amping, bridging, or driving demanding speakers with plenty of margin.

Why the Marantz AMP 20 stands out:

• 200 W per channel at 8 Ω provides ample headroom even at high volumes and difficult loads.
• Flexible configuration with bridgeable mode for up to 6 x 400 W, perfect for powerful LCR speakers. Or bi-amp up to six speakers for better separation between bass and treble.
• HDAM-SA2 combined with Class D delivers fast transient response and musicality you can hear immediately.
• Clean connections with 12 inputs where you can choose between balanced XLR or RCA per channel, plus premium SPKT-1+ speaker terminals that handle banana plugs and thick cables with ease.
• Seamless integration via the amp control cable that connects with the AV 20 (and is compatible with AV 30, AV 10, and others) so power and lighting are controlled together.

The AMP 20 is built to create that unforgettable cinema experience. Whether you need many channels, the twelve channels offer freedom without compromising sound quality. The copper-plated chassis and carefully selected components contribute to a clean, spatial, and dynamic reproduction where every detail—from explosions to whispers—comes through with life and precision.

Design-wise, it follows Marantz tradition: elegant, discreet, and exclusive. The classic porthole with level meters, metal front, and subtle side lighting make it look just as good in a dedicated home theater as in a stylish living room.
