Marantz AV 20

The Marantz AV 20 combines sophisticated sound architecture with comprehensive connectivity to meet the demands of the most ambitious setups. Featuring 13.4-channel processing, compatibility with all current multichannel audio formats, and a full HDMI 2.1 video section, the AV 20 stands out as a reference solution for enthusiasts seeking flawless sound quality and uncompromising versatility.

Exceptional Sound Architecture

The design of the Marantz AV 20 is based on an audiophile philosophy applied to the world of home cinema. Its copper-plated chassis significantly reduces electromagnetic interference, while its toroidal transformer delivers stable and precise power to critical components. Marantz’s signature current feedback topology ensures faithful reproduction of complex audio signals while minimizing harmonic distortion.

The exclusive monolithic HDAM SA3 modules form the analog heart of the device, providing exceptionally pure and fast voltage amplification. This approach contrasts with conventional integrated solutions and results in a more precise soundstage, better instrument separation, and a more natural reproduction of timbres.

The preamplification section supports up to 13.4 channels, enabling the implementation of sophisticated three-dimensional audio setups with multiple speaker layers and several subwoofers. Outputs are available in gold-plated RCA and balanced XLR for flexible integration with any type of amplification.

Advanced Multichannel Audio Processing

The AV 20 decodes all modern audio formats, offering full compatibility with current and future content. DTS processing includes DTS-HD, DTS:X, DTS:X Pro (up to 13 channels), DTS Virtual:X for simulating height effects, and DTS Neural:X for converting stereo sources to multichannel sound.

On the Dolby side, the device supports Dolby TrueHD, Dolby Atmos with its advanced height virtualization, and Dolby Surround for converting conventional sources into more immersive formats. Compatibility also extends to Auro 3D, Sony’s 360 Reality Audio, and the MPEG-H standard.

IMAX Enhanced certification ensures faithful reproduction of IMAX soundtracks when available on home media, preserving the original dynamics and scale.

To fine-tune the acoustic rendering according to the listening environment, the AV 20 integrates the Audyssey MultEQ XT32 system, capable of analyzing and compensating for the room’s acoustic characteristics with remarkable precision. Complementary Audyssey technologies—Dynamic EQ, Dynamic Volume, and Low Frequency Containment—respectively optimize tonal balance at low volume, level variations between programs, and bass overflow. An optional upgrade to Dirac Live, a particularly advanced calibration system, is also available.

Network Connectivity and Audio Streaming

The AV 20’s network platform is based on HEOS technology, allowing seamless integration into a multiroom audio ecosystem. WiFi, Bluetooth, and Ethernet connectivity ensure maximum flexibility for integration into any home environment. A particularly appreciated feature is Bluetooth retransmission to wireless headphones, enabling discreet nighttime listening without compromising quality.

The preamplifier supports high-resolution audio formats including FLAC and ALAC up to 192kHz/24bit, WAV, DSD up to 5.6 MHz, as well as more conventional formats like MP3, WMA, and AAC. Gapless playback is supported for FLAC, ALAC, WAV, and DSD formats, ensuring a smooth listening experience for concept albums or live recordings.

Compatibility with major streaming services is comprehensive: TuneIn, AirPlay 2, Spotify Connect, Amazon Music, TIDAL, Deezer, Napster, and Soundcloud are directly accessible. Roon Ready certification allows users of this advanced music management system to integrate the AV 20 into their audiophile ecosystem.

Video Performance and HDMI 2.1 Compatibility

The AV 20’s video section is future-proof, with seven HDMI inputs and three outputs (including one dedicated to multiroom setups), all compliant with the HDMI 2.1 standard. This allows transmission of 8K signals at 60 Hz or 4K at 120 Hz, with bandwidth up to 40 Gbps on seven inputs and two outputs in direct transmission.

Video processing includes upscaling 1080p and 4K content to 8K, as well as full support for HDR formats: standard HDR, HLG, Dolby Vision, HDR10+, and Dynamic HDR. Gamers will appreciate features such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and QFT (Quick Frame Transport), which significantly reduce latency and improve smoothness.

Comprehensive Connectivity

The AV 20’s extensive connections allow integration of virtually any analog or digital source. In addition to the seven HDMI inputs, there are two composite video inputs, one component video input, seven analog audio inputs (including one XLR), and an MM phono input for turntables.

The digital section includes two optical and two coaxial inputs, complemented by USB ports on the front (for temporary sources) and rear (for powering accessories). Multichannel preamplifier outputs are available in RCA and XLR for 15.4 channels, offering maximum flexibility for connecting external amplifiers.

Sophisticated Multiroom System

The AV 20 can manage up to three independent audio zones, allowing different sources to be played simultaneously in multiple rooms. Sources compatible with multiroom distribution include HDMI, optical, coaxial, network, USB, and analog inputs.

There are multiple control options: IP, RS232, web interface, dedicated app, and integrated HEOS system. Three DC trigger outputs allow automation of powering on additional equipment such as amplifiers or motorized screens.

Intuitive User Interface

Despite its technical complexity, the AV 20 remains accessible thanks to a refined user interface. Marantz’s signature circular OLED display is complemented by a two-line FLD screen. The HD graphical interface, available in nine languages, guides users through the various configuration options.

The automated setup assistant simplifies initial installation, while Smart Select buttons provide quick access to favorite presets. Firmware updates can be performed via the network or USB, ensuring features evolve over time.

Frequently Asked Questions

How does the Marantz AV 20 stand out from other high-end preamplifiers on the market?

The Marantz AV 20 stands out through its unique combination of analog audiophile technologies (copper chassis, HDAM SA3 modules, toroidal transformer) with the most advanced digital features. Its ability to process up to 13.4 channels, compatibility with all current three-dimensional audio formats, and full HDMI 2.1 section place it at the technological forefront, while preserving the warm and precise sound signature that has made Marantz famous.

Can I use the preamplifier with my older analog devices?

Absolutely. The AV 20 offers generous analog connectivity with seven line inputs (including one XLR) and an MM phono input for turntables. Composite and component video inputs also allow connection of older video sources. The high-quality analog circuit with HDAM SA3 modules ensures optimal processing of signals from these traditional sources.

Is the AV 20 compatible with the latest gaming consoles like PlayStation 5 or Xbox Series X?

Yes, the AV 20 is perfectly suited for next-generation consoles thanks to its HDMI 2.1 compatibility. It supports 4K signals at 120 Hz and 8K at 60 Hz, as well as gaming features such as ALLM (Auto Low Latency Mode) for automatically reduced latency, VRR (Variable Refresh Rate) to prevent screen tearing, and QFT (Quick Frame Transport) for improved responsiveness.
