Alexa Music Playback through Marantz / Denon Heos

Arising from a query on reddit, I revisited something I'd set up quite some time ago and forgotten all about: using Alexa to play music on my HT system. It works;

As can be seen, the processor is on CD input to start. When I ask it to play music, it switches to the HEOS input and plays. If the processor had been in standby, it would have been woken and switched to the correct input.

Also, only the music content plays through the speakers,, the Alexa responses come from the echo device itself.

Forcing HDR / Dolby Vision when not supported

 I came across VideoProcessor.org through a thread on AVSForums. From their own description, this sounded like something that might be of use for me to see how far I could push HDR on my venerable JVC X500 projector;

VideoProcessor turns a computer into a 4k HDR capable live video processor by connecting a video capture card to a renderer and taking care of details such as conversion, timing and HDR metadata.

This allows advanced renderers to do things like 3D LUT, HDR tone mapping, scaling, deinterlacing and much more which can significantly improve image quality on most displays and beamers.

It turned into quite the adventure, and when I finally got it working, I thought I'd write up the settings for posterity....

Streamer, with benefits

I've spent a while refining my a/v setup and finally got around to building a decent home for all the kit. It now all rests on a DIY pull-out and swivel rack that allows for access as needed. However, one of the problems with any rack is the proliferation of devices and cables. 

In the spirit of consolidation that underpins this blog,  I thought there must be a way of tidying all that up. So I started with a svelte computer case and starting adding stuff in until I was happy. 

Worth a Watch: DCX MMXVI

I don't really do content reviews on this blog, but this weekend I rewatched the live concert Blu-Ray included with The Dixie Chicks DXC MMXVI Live CD set and it blew me away all over again, so I thought I'd share!

I wouldn't call myself a Dixie Chicks fan per se, (or 'The Chicks' as they are now known). I have one of their CDs and know a few of the songs, but I don't know very much about them, their names, background etc. However, being a fan of live music videos, I picked up this set a few years on the basis that it included the concert blu ray, and was I pleasantly surprised.

Maybe the best gadget I've ever bought?

 

Fairly insidiously, Amazon has taken over my house.  I now have various iterations of FireTVs connected to each TV, and almost every room has an echo device.

I'm not complaining really, these are great pieces of technology, and voice control is a lot more useful that I would have envisaged a few years ago. 

And the FireTV is excellent - easy to use and supports everything I use on a regular basis; Netflix, Kodi, Spotify, Emby Amazon Video and more. However, there's one thing that' been bugging me -  it's lack of true bit-streaming of extended sound formats. I use Kodi quite a bit for my media library, and there are many titles in there with fancy surround formats that just don't make it out to my AV system unscathed.

This is only an issue in my Home Cinema which has a full 7.1.4 system that can make best use of such soundtracks (everywhere else is plain old stereo).

I've been reading about the nVidia Shield for a while and finally bought one to see if it could replace the FireTV in this room. Here's how I got on with it...

Marantz / Denon IP Control in Node-Red

I'm enjoying my recently acquired Marantz AV8805 processor which is now the heart of my Home Cinema. My previous trusty SR7010 receiver is still working hard as a power amp, driving surround and height channels.

One of the challenges of running in this kind of configuration is that both units respond to the same remote control signals. I have switched off remote receiving on the SR7010 as I just want it to behave as a power amp. However, as the 7010 has no trigger inputs (alas, only outputs), the problem remains of how to power up the SR7010, and power it down, in tandem with the AV8805.

Here's the end result;

Here's how this was done in Node-Red....

Total Harmony

It was getting quite ridiculous. This is the set of remotes I had built up to control my HT. From right to left; Receiver, NowTV box, PVR, FireTV, BluRay, Projector, Squeezebox, DAC.

It's little wonder no-one else in the family used the system!

In the past, I'd used various Logitech Harmony remotes but all had outlived their usefulness and have been retired. A few months ago, I'd picked up a Harmony Companion set on Amazon warehouse for a steal, but hadn't got around to configuring it all until now.

Marantz SR7010 receiver as 9 channel power amp

I've had my SR7010 for a couple of years now and it runs my 7.1.4 Atmos setup great. It's got tons of features and 9 in-built amps that are rated at 125W (two channels driven).

However, I'm starting to think about succession planning and something like an Anthem AVM60 processor would be nice or maybe the forthcoming Marantz 8805 or Emotiva RMC-1 which support more channels.

In any case, it's likely going to be a processor solution rather than an AVR. Which got me thinking about amps. There's plenty of amps in the SR7010 which, in combination with 3x higher-spec units for front l/r/c speakers, would be perfect for surrounds and heights.

The questions is - can you use the SR7010 as a power amp and access all 9 amplifiers. A quick test reveals YES, and here's how.

The first million is the hardest

So, after 4 years, 72 posts and 88,069 page views, this blog is about to pay dividends. I'm about to click over to €70 in Adsense earnings. This is the earning threshold at which they send on the cash so I'm about to get my first payment. Yay! Wonder what I'll blow it on?

I obviously don't maintain this blog for the riches and fame!

However, I'm keenly aware that I have hardly been maintaining it at all of late. This is largely due to the fact that MediaServer8 has been so stable and reliable recently. unRAID and all the plugins and dockers I use to run whole house storage and a/v have been ticking along quite nicely, thank you very much so I haven't had very much to write about on that front.

However, there are a few projects in progress and on the horizon that  are related and might be interesting. I've set up a secondary a/v system in our family room in anticipation of a pending Xbox One S acquisition and have installed a new A/V receiver there. I'm also updating the main home theatre with ceiling speakers to enable DTS-X and Atmos height channels. I'll also be replacing my X10 lighting control system with Z-Wave in the near future. Plus, unRaid 6.2 is out!

A lot of these projects are not directly related to home server, storage, NAS and virtualisation which have been the main topics of this blog for the past 4 years. However, they will all one way or the other tie into some back-end systems so I'm going to expand the subject matter beyond just MediaServer and start documenting wider a/v projects and the like.

Here's to the next €70!!!

Making Movies

I recently came across a review of the MOTU 1248 AVB external audio interface on yabb.jriver.com and figured it's the ultimate in flexibility for my needs - it would drive my home theatre sound system AND whole house audio system AND anything else I threw at it.

The only problem was the price - at over €1,600, it's somewhat pricey. (This blog has brought in the sum total of €50 over 2 years to give an indication of when I could afford it!).

However, it does have a baby brother, the Ultralite AVB which at under €900 would be a little more palatable. It would give 8x outs for the home theatre and can be expanded. Still out of range though, so I turned to eBay and found a Motu 848 MkII for a lot less that will work as in interim solution and will work as the ADAT expansion unit if I ever get the UltraLite.

I first tried the unit with a KVM Windows 8 VM in unRaid but found a lot of pops and clicks, particularly with higher resolution audio files. Additionally, when I introduced the longer FireWire cable I needed, it just wouldn't work at all. So with a tinge of sadness, I've retired one of my VMs and migrated it back to a physical HTPC that will run the home theatre.

So with that decision made, I set about re-configuring the HT A/V set-up. The biggest task was to physically move everything behind the screen. The photo above shows my current 110" 16:9 screen in position, but I can swing it up to reveal...
