The team at Marantz took great care to ensure the AV8805’s construction resulted in the best possible result when it came to unaltered movie and music playback. They have achieved this through the implementation of a highly rigid base – included as a foundation for all of the unit’s circuit boards carrying the sensible audio signal – in order to eradicate the chance of microphonic effects through unwanted vibrations.

An oversized toroidal transformer within the Marantz AV8805 has been included in order to feed the big main capacitors and is set on an extra 5mm aluminium pedestal to achieve greater stability. All electronic components are supported by the copper plating on the main chassis. This copper plating will guarantee only the best ground connection at any point, and will improve Signal to Noise behaviour significantly. A total of seventeen single board HDAM modules have been used within this Pre-Amplifier in order to produce perfect channel separation for a reference-setting audio performance. And to finish it off, everything within the AV8805 is covered well by a heavy top lid that has been constructed using three pieces.

HDMI Connectivity and eARC Object-Based Audio Support
The HDMI section on the AV8805 ensures that this unit is ready for the future of home entertainment. Featuring all of the latest HDMI and HDCP 2.2 specifications over all eight HDMI inputs, this Pre-Amplifier will offer support for virtually any HDMI component. Experience only the best in home cinema entertainment with support included for 4K Ultra HD (UHD) 60Hz video, 4:4:4 Pure Colour sub-sampling, High Dynamic Range (HDR) and 21:9 video, 3D, and BT.2020 pass-through over every input. The unit is compatible with 4K Ultra HD Blu-Ray disc players, set top boxes and other 4K Ultra HD sources, and supports Dolby Vision, HLG (Hybrid Log Gamma), new HDR format for broadcasting, and pass-through capabilities.

The HDMI section also offers HDMI eARC Object-Based Audio Support, a function that supports the transmission of 3D audio from your TV apps with a single HDMI connection. This single HDMI connection provides the simplest setup, and ensures you can achieve the perfect audio experience through all TV integrated apps hassle-free. eARC Object-Based Audio Support will be enabled via a future firmware update.

Dolby Atmos Support
The Marantz AV8805 will offer support over Dolby Atmos surround sound technologies, allowing you to experience the breath-taking sound effects that one would expect when watching a movie at the cinema, right in the comfort of your own home. Atmos technology will completely envelop you in your movie, and really make it feel as though you are right there in the middle of the action.

The sole intention of Dolby Atmos is to make it feel as though you are truly in the middle of all the action. Providing a clarity, power, detail and depth to your home theatre that is truly astonishing, Dolby Atmos is the first home theatre system that has been based on audio objects rather channels. This means that filmmakers are able to decide where the sounds should originate from and where abouts they should move to as the scene progresses. In order to deliver the full object-based soundtrack to your home theatre, Dolby has developed new home authorizing tools and new encoding methods that will allow all the audio objects created for use within a cinema to be used within the comfort of your own home.
