Description

Overview

The Marantz AMP 20 is a remarkably powerful 12-channel reference power amplifier, crafted in Shirakawa, Japan, and designed to pair seamlessly with the AV 20 preamplifier for an elite home theater system. Built on Marantz's exclusive HDAM-SA2 circuitry and high-efficiency custom Class D switching amplification, it delivers 200 watts per channel with exceptional control and clarity across complex multichannel speaker systems, making it the ideal partner for large-scale custom installations.

Key Features (with "why it matters")

  • 12 channels of 200 W amplification (8Ω)
    Provides ample, evenly matched power for even the most demanding multi-channel Atmos/DTS:X speaker layouts.
  • Exclusive HDAM-SA2 & custom Class D switching amps
    Combines Marantz's signature musicality with the efficiency and thermal control of Class D design.
  • Bi-Amp and BTL (Bridged) Drive modes
    Lets you reconfigure channels for higher power in fewer zones or bi-amp demanding speakers for better control.
  • Balanced (XLR) and unbalanced (RCA) inputs, selectable
    Balanced connections reduce noise over long cable runs in custom installations.
  • Front-panel level meters
    Provides a visual reference of real-time output across channels — a hallmark reference-amplifier touch.
  • Copper-plated chassis
    Reduces electromagnetic interference for a cleaner signal path and improved channel separation.

  4. After Sales Support - The only issue with Hi-Fi equipment is that you will not find local service centers in every city. Most of the brands have their service centers only in the metro cities and hence it becomes difficult for the customers who are living far away places to claim warranty. At AV Kart, we solve this problem by arranging pikcup and drop facility from the nearest service center with the help of our logistic partners.
