About the Marantz AMP20
The AMP20 is a 12-channel power amplifier built as the natural amplifier partner for the Marantz AV20 preamp/processor, giving a large dedicated theater the channel count to drive a full Dolby Atmos speaker layout from one chassis. It pairs Marantz's exclusive HDAM-SA2 circuit design with custom-developed Class D amplification across all 12 channels, engineered to combine the brand's signature warm, dynamic sound with the high channel count a big system needs.
Each of the 12 channels delivers 200 watts into 8 ohms, rising to 400 watts into 4 ohms, with 0.05% THD and a minimum rated impedance of 4 ohms. Channels can be bridged for 400 watts per channel where fewer, more powerful channels are needed. The classic circular porthole level meter and premium build carry Marantz's design language through from the AV20 preamp/processor it's designed to pair with.
Twelve inputs feed the 12 channels one-to-one, with binding post speaker connectors on every output and a removable IEC 3-prong power cord for easy cable management and replacement.
