Sophisticated Engineering
With 11.2 channel pre-outs on both conventional RCA sockets and balanced XLRs, the AV7705 is designed to work alongside high-quality external power amplifiers like the Marantz MM8077, MM7055 and MM7025. Not only is it a superb AV processor, the AV7705 is an extraordinary analogue preamplifier with an HDAM circuit board. Using Marantz-proprietary HDAMs, the preamp section of the AV7705 provides optimal channel separation, minimum crosstalk and enhanced signal to noise ratio for precise detail resolution and stereo imaging, while the ELNA capacitators of the analogue section ensure exceptional power and dynamic ability.
Supports Latest Object-based Audio Formats
Immerse yourself in multi-dimensional audio with Dolby Atmos, DTS:X, Auro-3D and DTS Virtual:X. Set up a Dolby Atmos surround sound speaker system up to 7.1.4 using Dolby Atmos elevation speakers or dedicated overhead speakers for the ultimate home theatre experience. DTS:X™ immersive audio places sound where it would occur naturally in space, creating a lifelike, multi-dimensional audio experience in the home. The improved immersion and heightened realism draw you into the world of your favourite movies. The included DTS Neural:X™ gives your movies, games and music a realism unmatched by traditional 5.1 surround sound. Auro-3D® elevates the home theatre experience with three-dimensional sound for music, games, broadcast and films with enhancing your existing audio-visual collection, thanks to Auro-matic up-mixing engine. DTS Virtual:X provides immersive audio without height channels, creating virtual height effects in a 5.1, 7.1 or 2.1 speaker arrangement.

    I like how Marantz literally built the Fuse board first, and then layered everything else around and over it. Makes it nice and easy to check if your fuses are blown., seems like just a few hours of work and only a handful of screws that will never get put back

    Hi.. I am a big fan of your teardown videos and enjoy them a lot. I also like the fact that you are tearing down gear that is accessible and not something niche only for the super rich. Looking at the fact that you own(ed) an AV7705, I am tempted to ask what is your opinion of the device and its sound quality? I ask because it got terrible review on audiosciencereview . Do you notice any flaws in day to day usage? Thanks

    First of all thank you for such a great response! Personally I'm very happy that I have decided to buy AV7705 instead of SR7013, it opened me whole lot of opportunities. Sound wise, when I swapped my SR7500 to AV7705 I heard significant difference. Sound was great. Even when I have updated to AV8805A the difference wasn't so noticeable. And I did not experienced any issues with my unit. I believe it's a great product for its price range.

    Thanks for you comment. Unfortunately I don't have I plan to make a video about Marantz SR7015 at this moment. These are my personal Marantz components, no one is providing me with them. So I'm a bit limited from this perspective. However, teardown video of Marantz MM8807 7 channel amplifier is almost ready, and hopefully I will upload it in about a week. Also I'm hoping to make a video about Marantz AV8806 as soon as (and if...) it comes out.

    I know preamp XLR output is 4 volts max. If you run it thru XLR to RCA converter, does the voltage drop to around 2 Volts? In other words, XLR output is capable to play music louder than RCA. Am I correct?
