11.2 channels envelop you

The AV7705’s 11.2-channel capability can be configured for one elaborate single-room surround system, or up to three separate zones anywhere in the house. Each channel connects to your companion amplifier via gold-plated RCA jacks or professional balanced XLR connectors for the lowest noise floor.

Superior surround all around

Object-oriented surround formats Dolby Atmos and DTS:X precisely place effects all around you – front, side and back – plus add overhead channels for truly soaring effects; Auro-3D creates a three-layer “cocoon” – surround, height and overhead – for what claims to be the most immersive experience, whether with games, music, movies or broadcast TV. And Virtual:X, as the name implies, creates a convincing height effect from any standard surround system.

HDAM circuitry for cleaner sound

Instead of pulling integrated circuits off the shelf, Marantz engineers craft circuitry 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.

Solid Platinum sound

Different dimensions, furnishings, speakers, sonic signatures – the AV7705 digitally adapts to where and how you listen, with the Audyssey Platinum software suite.  With MultiEQ XT32 and the included microphone, you simply sample measurements around the room to optimizes each channel for frequency response, time domain and reflection differences. Dynamic Volume and EQ corrects in real time for volume variations so you can listen at lower levels with clarity. Low Frequency Containment delivers full, deep bass without shaking the neighbors awake. Sub EQ HT tweaks each of two subwoofers separately for better-defined bass lines. And the Audyssey MultEQ Editor app (available at additional cost for iOS and Android) lets you micro-manage the settings for more personalized customization.

High-def HDMI hookups to spare

With 8 HDMI inputs and 3 outputs, the AV7705 is ready for the most complex video setups. All offer pass-through support for the highest quality enhancements, 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 Dolby Vision for today’s movies, and Hybrid Log Gamma for future broadcasts. Upscaling circuitry lifts both standard definition and 1080i high-def sources to near-4K quality.

Endlessly, wirelessly versatile

With dual-band Wi-Fi, audio-quality Bluetooth and Apple’s AirPlay 2 all standard equipment, the AV7705 is ready to stream whatever you’ve got, from whatever devices or home-server setup you have. And you get Denon/Marantz’s marvelous multi-room HEOS system built in, for app-based control of HEOS speakers in every room of the house and easy access to the full slate of celestial jukeboxes, including Spotify, Tidal, Pandora, Amazon Music, Tune-In, Deezer, iHeart Radio, SiriusXM and Rhapsody.  

Hi-res ready

Today’s music tracks aren’t limited to the 16 bit, 44.1 kHz sampling rate designated for CDs in the mid-1980s. The AV7705 handles the latest high-resolution audio files, including ALAC, FLAC and WAV, up to 24 bit/192kHz, and DSD up to 5.6 MHz, along with the full range of remaining formats (including MP3 and AAC) through both the front-panel USB port and wireless streaming.

The IMAX seal of approval

The AV7705 is the first premium pre-amp to be certified under the new IMAX Enhanced program, which sets stringent standards for image and sonic performance, as well as improving the movie mastering process, to better and more consistently recreate the theatrical experience in your own living room.

Talk to me, baby

You have many ways to harness all this power and all these features. Of course, you get the usual remote control. Or you can download the Marantz 2016 AVR app for iOS and Android (yes, a couple years old but still completely relevant) for pad or phone control. Or just ask Alexa or one of her voice-control cohorts: The AV7705 supports Amazon’s intelligent assistant, plus a growing library of commands through competitors Apple Siri, Google Assistant and the whole-house custom automation system

Great Unit works well
It was an update for my our system. It replaced an old processor (10+ years). And runs well and is great value for the money. Only complaint I have is about the auto sensing for HDMI. Had to turn that off. It kept trying to switch to another input then switch back. (I think the Issue was caused by a unit on another HDMI input). And I really like the HEOS and blue tooth audio..
And just can't give 5 stars to anything -- and 4.5 isn't possible

How many watts per channel on this Ave?
A shopper on Jul 8, 2019
  None, this is a preamp/processor which requires separate power amplifiers to operate.
