Marantz AMP 30 Slim 6-Channel Class D Power Amplifier

Marantz AMP 30 Power Amplifier

The Marantz AMP 30 is a remarkably powerful, slimline 6-channel home theater power amplifier designed to bring effortless dynamics, clarity, and control to immersive speaker systems. With high-efficiency, low-distortion Class D amplification and Marantz-exclusive HDAM technology, AMP 30 delivers the brand’s signature rich, warm presentation while providing the current and headroom modern surround formats demand. Rated at 200 watts per channel into 8Ω (and 400 watts per channel into 4Ω), it’s built to drive dedicated theaters with confidence—whether you’re powering a full surround bed, height channels, or demanding speakers that benefit from extra authority.

System building is where AMP 30 shines: pair it with the Marantz AV 30 or compatible Marantz AV receivers/separates for a cohesive, premium theater stack, then expand as your system grows by adding more AMP 30, AMP 20, or AMP 10 amplifiers. Flexible output modes—including Bi-Amp and BTL—let you tailor channel power for your layout, while balanced XLR inputs help reduce noise in high-performance installations. Finished with timeless Marantz design cues—like the iconic porthole analog level meter and soft side lighting—AMP 30 looks as refined as it sounds. The Marantz AMP 30 is part of ListenUp's Marantz AV Separates Collection.
