Marantz AMP 20 - Black

Description

Reference-Grade 12-Channel Amplification for High-End Systems
The Marantz AMP 20 is a premium 12-channel reference power amplifier engineered to complement the most advanced AV preamplifiers, including the Marantz AV 20. Delivering up to 200W per channel (8 ohms) and 400W in BTL (bridged) mode, the AMP 20 provides robust, clean power across multiple speaker configurations. Designed for ultra-low distortion and effortless dynamics, it brings clarity and punch to complex multi-channel setups, immersive surround formats, and bi-amp or bridged speaker deployments.

Pure Performance Through Advanced Engineering
At the core of the AMP 20 is a precision amplifier topology optimized for both balanced and unbalanced input stages, selected via an exclusive rear-panel switch. Each of its 12 independent power amps is capable of stable high-current output and tightly controlled damping, ensuring optimal drive for demanding speaker loads. The chassis is copper-plated for enhanced shielding and thermal stability, while the internal layout is engineered to minimize signal path interference and cross-talk.

Flexible Integration for High-Channel Count Systems
Supporting bi-amp and BTL drive modes, the AMP 20 can be configured for 12-channel, 6-channel bridged, or mixed applications, making it ideal for Dolby Atmos®, DTS:X®, and other high-channel count formats. Connectivity includes balanced XLR and unbalanced RCA inputs, with robust speaker terminals designed to accommodate large-gauge wire and spade or banana connectors. RS232 control, IR flasher input, remote bus, and 12V triggers ensure seamless integration into custom installations and control systems.

Signature Marantz Craftsmanship and Design
Built to the same high standards as the Marantz AV 20, the AMP 20 features a sculpted aluminum front panel with illuminated level meters, reinforcing its premium aesthetic and utility. The front display not only signals operational status but also reflects the amplifier’s dynamic output in real time. The chassis construction is solid and resonance-free, with meticulous attention to component placement and vibration control to preserve sonic purity.

Efficient and Intelligent Power Management
Despite its substantial output capability, the AMP 20 is designed for energy-conscious operation. Power consumption is rated at 400W during operation and just 0.2W in standby mode. Auto power-off functions further support efficient energy use without sacrificing readiness or performance in demanding multi-source environments.
