HDMI eARC Object-Based Audio Support

eARC (Enhanced Audio Return Channel) supports the transmission of 3D audio from your display's apps over a single HDMI cable for a simple setup.

IMAX Enhanced Technology

IMAX Enhanced certification designates that the AV7705 meets certain audio and video performance criteria set by a committee of IMAX and DTS engineers and A/V technical specialists. These criteria include image, sound, scale, and content quality. Onboard IMAX calibrated modes are set and approved by Hollywood colorists to help provide enhanced picture and sound for HDR UHD content.

Hi-Res Audio

Enjoy the fidelity of high resolution audio with the ability to decode up to 24-bit/192 kHz ALAC, FLAC, and WAV lossless files, as well as DSD 2.8 MHz and 5.6 MHz tracks (the audiophile format of SACD). Play hi-res music, MP3s, and other popular file types via the front-panel USB port and network sources.

32-Bit D/A Conversion on All Channels

For augmented fidelity and dynamic range with low distortion, the AV7705 features 32-bit AKM D/A converters on all channels, helping to ensure high fidelity and precise channel matching across all channels.

Marantz HDAM (Hyper Dynamic Amplifier Module) and Current Feedback Topology

The AV7705 features multiple HDAM modules, which are engineered to provide a fast slew rate, wideband performance, and enhanced dynamic range for optimum sound quality. Current Feedback technology, rather than the typical voltage feedback configuration, helps provide a wide, closed-loop bandwidth and steep slew rate to further augment fidelity with wideband audio sources.

Phono EQ Stage with HDAM

The HDAM is designed to outperform op-amp solutions with its higher speed, helping to keep the audio signal clean and tuned for enhanced sound performance.

Dual Subwoofer Outputs

The AV7705 features two subwoofer outputs to help smooth out low frequencies and enhance bass dispersion, mitigating peaks and audible dips.

Designed for Easy Setup

Once you connect your display to the AV7705 via HDMI, the Marantz Setup Assistant appears on the screen to guide you through the setup, helping you establish settings to help achieve the best sound quality for your configuration.
