Marantz AMP 20 - 12-channel power amplifier for home theater and high-end audio

The Marantz AMP 20 is built for home theaters where both movies and music must be reproduced with control, dynamics, and ease. It delivers 200 watts per channel and drives even demanding speakers without losing composure or balance. At the same time, it follows Marantz’s well-known sound philosophy, where power and musicality go hand in hand.

The AMP 20 suits systems where you want to bring many channels together in one solution—without compromising on sound quality.

Power for large home theaters

The AMP 20 keeps even large home theater systems under control. The 12 channels provide plenty of flexibility, and the high power ensures that movies, music, and gaming are all reproduced with ease.

If you need even more power for the front speakers, you can bridge the channels and get up to 400 watts per channel.

Marantz sound with a focus on musicality

Marantz developed the AMP 20 with a focus on both power and musicality. The HDAM-SA2 circuits work faster and more quietly than traditional solutions and help preserve detail and dynamics in the signal.

The result is reproduction with more air, better separation, and a more natural balance across the entire frequency range.

Stable construction with low noise

The cabinet uses copper plating, internal bracing, and vibration damping to keep noise down around the electronics. The separate toroidal transformer also contributes to a more stable power supply.

This creates a darker background and helps the music stand out more clearly in the room.

Flexible integration into your system

The AMP 20 supports both balanced XLR and RCA connections, making it easy to integrate into different home theater setups. It pairs naturally with the Marantz AV 20, but also fits into other high-end systems.

Bi-amping and trigger connectivity also provide extra flexibility in larger installations.

Design with classic Marantz identity

The front combines aluminum, discreet lighting, and the characteristic VU meter, which gives the AMP 20 a distinct Marantz look. The construction feels solid and well-executed, both visually and mechanically.

This makes the AMP 20 a power amplifier that fits naturally into dedicated home theaters and serious hi-fi systems.
