Marantz AV7704 11.2 Channel Full 4K Ultra HD A/V Pre-Amplifier with HEOS Overview

For most movie fans or music mavens, today’s feature-packed receivers (such as Marantz’ own exceptional SR7012 and superlative SR6012) offer more than enough power and flexibility. But those who demand the ultimate fidelity from their home theater systems, whether watching Star Wars or auditioning a string quartet, often opt for separates – pairing a digital preamp/control unit with audiophile amps ideally matched to speakers. Marantz’ AV7704 11.2 Channel 4K Ultra HD A/V preamp marries the company’s storied craftsmanship with leading-edge technological prowess. It handles all A/V sources from treasured vinyl to streaming media with equal care, and can serve as the foundation of the finest home systems.

11.2 channels, for sound everywhere

The AV7704’s 11.2-channel capability (the .2s stand for subwoofers) can be configured for one elaborate single-room surround system, or up to three separate zones anywhere in the house. Each channel connects to its amplifier via gold-plated RCA jacks or semi-pro balanced XLR connectors for low noise.

Surround formats: Above and beyond

Dolby Atmos and DTS:X put up to 7 channels around you – front, side and back – and add up to 4 channels overhead for truly soaring effects; the latest systems’ object-based encoding places every sound precisely in the listening space. Auro 3D creates a three-layer “cocoon” – surround, height and overhead – for what claims to be the most immersive experience.

HDAM circuitry for cleaner sound

Instead of pulling integrated circuits off the shelf, Marantz engineers craft their pre-amp circuits in-house using precise, discrete components, in a configuration the company calls Hyper Dynamic Amplifier Modules.  You get wider soundstage, deeper dynamic range, and more detailed music and soundtrack reproduction.

Audyssey: The Platinum difference

Different rooms, dimensions, speakers, sonic signatures – even different sofas. The AV7704 adjusts to every listening environment with the extensive Audyssey suite of digital correction systems: With MultiEQ XT32 and the included microphone, you sample measurements at up to 8 locations around the room and the system optimizes each channel for frequency response, time domain and reflection differences. Dynamic Volume and EQ corrects in real time for wide variations so you can listen at lower levels with clarity. Low Frequency Containment delivers full, deep bass without shaking the neighbors awake. And Sub EQ HT adjusts each of two subwoofers separately for better-defined bass lines.

Digital music: Hi-res ready

Today’s tracks aren’t limited to CD’s 16 bit, 44.1 kHz sampling rate. The AV7704’s digital decoders handle high quality, high resolution files up to 24 bit/192kHz and DSD 2.8 MHz and 5.6 MHz, with the full range of formats (and acronyms including MP3, ALAC, FLAC, WAV and SACD) through both the front-panel USB port and via wireless network streaming.

HDMI galore, for endless video vistas

With 8 HDMI inputs and 3 HDMI outputs, the AV7704 can handle the most complex video systems. All offer pass-through support for the latest protocols and formats, including HDMI 2.0 with HDCP 2.2, 4:4:4 Pure Color, widescreen 21:9 ratio, BT.2020, and of course 4K Ultra HD with High Dynamic Range (HDR), and even the latest Dolby Vision, just starting to roll out to the market. And the AV7704 is future-proofed thanks to upgradable firmware. It even offers built-in tools for those who prefer professional video calibration.

One versatile entertainer

How do you fit such a flexible performer into your personal lifestyle? Actually, with ease: Pipe your music into the AV7704 and all around the house through a variety of wireless systems, including built-in dual-band WiFi, Bluetooth and Apple AirPlay. With the AV7704’s built-in menu-driven Setup Assistant, full-featured remote and downloadable Marantz 2016 AVR app for Android and iOS, configuration and control of every feature of this complete system is simplified. 4 Smart Select buttons store your favorite sources, Internet radio stations and preferred settings. And even voice control – via the ubiquitous, friendly Amazon Alexa – will be available soon, via download and firmware update.

HEOS for room-to-room quality

HEOS, a simple, app-based streaming system available in various equipment across the Marantz and Denon lines, sends separate sources all around the house. Create your own playlists, and control everything from your smart phone or tablet. Stream your favorite music seamlessly from your own home network, or plug into the celestial jukebox with services including Pandora, Spotify, Tune-In Radio, Amazon, Tidal, SiriusXM, iHeart Radio, Napster and Deezer.

Bonus: It’s a Marantz

From the time Saul Marantz engineered his first amplifiers in the early ‘50s, the brand has been synonymous with high-end hi-fi, crafting enduring classics. The AV7704 carries on that tradition with unparalleled flexibility and sonic excellence. Marantz’ motto is “Because Music Matters,” and nowhere is that care in sound reproduction –from soundtracks to sonatas – more evident than in the this unit.

Pairs perfectly with…

Suitably top-notch power amplifiers (such as Marantz’ own MM8077 7-channel unit) and equally high quality speakers (among our recommendations is the Klipsch RP-250 7.2 channel reference system), to anchor the finest home theaters and most musical systems available.
