The AMP 20 is a remarkably powerful 12-channel amplifier. Pair with AV 20 and any of our CINEMA Series products for an elite, reference-level home theater system. AMP 20 is rated at 200 watts per channel into 8 ohms and 400 watts per channel into 4 ohms. AMP 20 is built on Marantz exclusive HDAM and redesigned Class D amplification.

• Ultimate Performance: AMP 20’s custom-developed Class D amplification and refined HDAM-SA2 technology create the most incredible theatrical experience possible in your home. It cleverly combines very high- power output and high channel count to create a master reference-level amplifier for ultimate home theater performance. Separate power supplies for line level and high-power stages ensure total signal purity from input to output.
• Sound Master Tuned: Our Marantz Sound Master meticulously tuned AMP 20 for amazing performance with careful parts selection to create outstanding sound in your home. Making sound the Marantz way is a seamless fusion of art and science, practiced by creators who balance and select components individually for their sonic qualities—they are the Sound Masters.
• Timeless Style: Excellence is heard and seen. AMP 20 is meticulously crafted with authentic materials in a modern style befitting its rich heritage and stunning performance Marantz design is timelessly elegant. AMP 20 is elegantly constructed using steel and aluminum casework while the subtle texture molded into the frontpanel is lit by the dimmable soft glow of sidelights on either side of our iconic porthole design
• Endlessly Customizable: Marantz has provided a rich assortment of connections and configuration options to make AMP 20 your ideal amplifier. While each of the 12 channels can operate independently, channel pairs can also be switched into bi-amp mode for isolating frequency bands from each other or switched into BTL mode to produce up to 400 watts per channel into 8 ohms for your highest output demands.
• Effortlessly Powerful: AMP 20 gives you 12 channels of commanding power in a single enclosure each rated at 200-watt-per- channel amplifier to perform at extraordinarily high levels with no loss in fidelity. Custom Class D amplification is highly efficient, and strategically incorporated whisper-quiet fans keep the unit running optimally even under highly dynamic conditions.
• Complete Compatibility: Gold-plated RCA and high-grade XLR connectors accept audio input from most surround processors. Custom Marantz SPKT-1+ binding posts are ergonomic and provide the best possible coupling to loudspeaker cables. Low-distortion, high-power output provides ample drive to virtually any loudspeaker configuration to maximize performance
