Marantz AV7704 11.2 AV Pre-amplifier (2018) | Pre-Owned

For optimum fidelity and the widest dynamic range with lowest distortion, the AV7704 features advanced reference-class 32-bit AKM D/A converters on all channels. This ensures consistent high fidelity and precise channel matching across all channels for the ultimate listening experience.

Featuring exclusive Marantz HDAM (Hyper Dynamic Amplifier Module) technology found on our Reference Series components, the AV7704 incorporates multiple HDAM modules which provide superior low noise wideband performance in an all-discrete configuration, compared to conventional op amp ICs. HDAM technology provides an ultra fast slew rate for true wideband response and maximum dynamic range to deliver optimum sound quality with today’s high resolution audio formats. In addition to HDAM technology, the AV7704 also features Current Feedback instead of the typical voltage feedback configuration. A Marantz innovation introduced on our very first audiophile amplifiers more than 60 years ago, Current Feedback technology provides a wide closed-loop bandwidth and very high slew rate, delivering superior fidelity with wideband audio sources.

Equipped with the flagship Audyssey suite of features, the AV7704 features Audyssey MultEQ XT32 automatic room acoustic correction using advanced DSP algorithms. With the supplied measurement microphone, it analyzes the output of each speaker (including the subwoofers) at up to 8 measurement locations, then generates precision digital filters that optimize each channel for the bets possible sound. Audyssey Dynamic Volume smoothes out annoying jumps in volume (such as TV commercials), letting you listen at lower levels while still enjoying clear dialogue, music and sound effects, while Audyssey Dynamic EQ provides full-range clarity at any listening level. Audyssey Low Frequency Containment uses advanced psychoacoustic algorithms to deliver a full-range balance, including deep bass, but without disturbing close-by neighbours or those in other rooms, and features a multi-step adjustment. Audyssey Sub EQ HT provides individual DSP tailoring of each subwoofer in a dual subwoofer setup, allowing deeper bass with improved definition when compared to a single subwoofer configuration.

The AV7704 supports the brand-new Audyssey MultEQ Editor App. Go ‘under the hood’, view and adjust settings for detailed tuning, customize the sound more precisely to the specific problems in your room, and tailor the sound to your personal preferences.

• View the speaker detection results, to check correct installation.
• View before and after results of the Audyssey calibration, making it easy to identify room problems.
• Edit the Audyssey target curve for each channel pair to suit your tastes.
• Adjust the EQ frequency adjustment range for each channel pair.
• Switch between 2 high frequency rolloff target curves.
• Enable/Disable midrange compensation to make the vocal region brighter or smoother.
• Save and load calibration results.

The Audyssey MultEQ Editor app, for Android and iOS, is available for purchase from the Apple AppStore or Google Play Store.

A single subwoofer demands optimal placement to avoid audible peaks and dips in the low-frequency response at the main listening position. The AV7704 supports two subwoofers: used in different locations, these will even out the low-frequency response for more accurate bass anywhere in the room.

Whatever your family’s entertainment needs, the AV7704 delivers: you can enjoy 7.1-channel surround sound in the main room, and at the same time play stereo sound from another source in a different part of the house. There are versatile configuration options thanks to the 11 channel processing capability.

The AV7704 has four Smart Select buttons on the front panel and the remote control: each stores a preferred setup – input, volume and Audyssey configuration – for a particular source. Push one button and the AV7704 can be perfectly configured for anything from Blu-ray or your TV set-top box to your favourite Internet radio station.

For easy installation, the AV7704’s clear graphical on-screen display has an exclusive Setup Assistant, combining with the Quick Start guide to provide guidance and optimise critical settings for the best possible sound quality, whatever your configuration.
