What new upmixer? I do know what upmixer means, just not sure what is "new", is it from the last FW update? Thank you.
It came with my 7705. When playing a 2 channel recording, if you press pure, you get two channel stereo. If you press music, then you get these onscreen options.
Dolby Audio-Digital surround.
DTS Neural-X
Auro 2D surround
Multi channel stereo.
Virtual.
When you engage them the speakers activated show up in the front panel of the 7705
Of those I have tried the top three. The Dolby up mixer is by far the best and very convincing and natural. It is just amazingly good. It up mixes 2 channel stereo to 7.2.4 in a very convincing manner.
DTS is fair, but seems to have some harshness to it.
Now I never included a "Voice of God speaker for the Auro 2D and I find that one very unconvincing. The Dolby-Audio-Digital is superb.
So good that in the organ I sighted in another post, where the division playing the flute part is place to my right in a convincing manner with the right front and right surround becoming in effect a stereo pair. The reed paying the melody is dead ahead. The uncanny thing about this mixer, is that not only does it have good localization 360 in the room, but also from floor to ceiling.
This was the undoing of a couple of my JW ceiling speakers. I was listening to the Organ Prom with no audience in the RAH on August 29. Jonathan Scott gave a bravura performance. He even played his organ transcription of the Organ Symphony by Saint-Sens. He played the organ solos and the orchestra parts at the same. At some periods he played all four manuals and the pedals at once, using the thumbs down technique.
Well the BBC announcer said that all the paneling in the hall was shaking and her chest was vibrating. Well you know my insanity. I had to reproduce that here, and could. You could clearly tell you were under the huge dome of the RAH, and hear its reverberation. Absolutely stunning. Anyhow the "Voice of Jupiter" damaged a couple of my vintage JW modules when Hollywood could not. That organ by the way when commissioned in 1871, was powered by two enormous steam engines.
It is a very loud instrument when called on. Jonathan Scott said it used to have a health and safety warning at the console, but organists would pinch them!
Anyhow I have replaced the JW with their latest successor from Mark Audio. They take three times the power. In the 0.25 cu.ft sealed boxes they have an f3 of 90 Hz, and extend to 25KHz, with a response smoother than most tweeters.
The performance is still on iPlayer and I think will be for another 8 months or so. I do have the audio from it on the hard drive of my DAW in any case. It is by far the best total work out of any system.
But the bottom line is, I have no idea what the Dolby engineers have done to create this astonishing effect. I can attest, that it works, and works well. It also up mixes Dolby 5.1 and 7.1 to 7.2.4 and I suppose 7.2.6. I have four ceiling speakers which I think is optimal for this room. The DTS does the same thing with DTS material.
As I have said before all the speakers need to be capable and very accurate to get optimal effect. For this to work, any old speaker for surrounds, rear backs and ceilings will not cut it.
