Warm, rich, and spacious sound. Elegant to behold. Marantz 50 series strikes a perfect balance between timeless and modern.
Features
The Marantz amplifier is designed to deliver high-fidelity audio with precision and musicality. Its dual-channel configuration, combined with a current feedback topology, ensures clean and dynamic sound reproduction. The Marantz Musical Phono EQ and proprietary HDAM SA3/SA2 circuits enhance detail and clarity across all audio sources. A toroidal power transformer, high-grade audio components, and custom-designed parts provide stable and pure power, while a symmetric PCB layout and aluminum extrusion heat sinks contribute to thermal efficiency. Users can adjust balance, bass, treble, and loudness to tailor the sound, supported by a linear drive power supply, linear volume control, and solid heat sinks. The unit also features a low-noise OLED display for clear monitoring, source direct and power amp direct functions for unaltered audio playback, and a robust triple bottom plate for structural stability.
For connectivity, the amplifier offers multiple audio inputs, including phono MM support, and versatile output options like pre-out, main-in, and power amp direct in. Gold-plated speaker terminals and support for dual speaker sets ensure reliable signal transmission. Performance-wise, it delivers 70 W per channel at 8 Ω and 100 W at 4 Ω, with a wide frequency response up to 100 kHz and minimal distortion. High signal-to-noise ratios across inputs ensure a clean listening experience, while adjustable treble and bass allow for personalised tonal shaping.
Aesthetically and functionally, the amplifier is built with a metal front panel and available in black or silver-gold finishes. Energy-efficient operation includes auto power-off and a standby consumption of only 0.3 W. The system is easy to integrate into existing setups via its detachable power cable, system remote functionality, and ergonomic dimensions, weighing 14.2 kg.
