Turned out I didn't know the 972 needed to be set to the USB input to get the last file from the memory stick.
Update done and seems to have addressed the issues, but I can't get lossless audio so can't say much.
Excerpts from our emails:
Based on suggestions and comments from you and others, Trinnov has developed a way to adjust bass level without having to run a new calibration. This does require updated the factory.hex file but does not require a new calibration. The factory.hex update is done by copying the file to a USB stick/thumb drive. The only file that can be on the stick is the factory.hex. After copying the file to the usb stick, turn on the receiver and select the USB input. After a few brief moments (3 to 5 seconds) the receiver will recognize that the file is an update. The 972's front panel display will flash UPDATE for about 1 minute. When the update is complete, the message UPDATE OK will appear on the front panel. Remove the USB stick and use the receiver normally. You do not need to reset the receiver after updating the .hex file.
Please find a zip file attached. When unzipped there are three versions of the factory.hex file. Burn one to a USB stcik, follow the directions above and load one into the R-972. The represent 3 bass levels. One is laboratory correct; one is 3 dB louder and the other is 6 dB louder. Please use the one you find most pleasing."
Do these different levels do anything other than change the sub trim level? If not, most everyone has a control on their sub that would be easier to adjust than loading a new file.
As far as the new f/w, it's good news/bad news, mostly good I guess.
The upgrade definitely made setup more robust, but not completely so.
With the mike lower than before but still higher than the listening position, it went OK but not w/o the surrounds still needing more than the standard 3 bursts.
It gave XO freq for all the main channels and sub -6 dB freq which is cool.
One of the setups reported the sub's horizontal angle as 90 deg, which was odd.
I tried a rotated soundstage setup and it worked, though not exactly as I expected.
It was pretty far off on the surrounds' angular positions, like 20 deg. I put a piece of foam on one side of each tweeter to monopolize them but it didn't help.
I don't much difference in bass, but hard to say w/o more extended listening which I didn't have time for.
The tonal balance was even more toppish than before, to the point of being "shushy", even with Cinema ReEQ on.
When I put the mike at actual listening position height, it took 3 tries before not failing on one or both of the surrounds.
But the third try was good and the angles were a lot closer on the surrounds, which makes sense when you look at the geometry.
Sounds maybe more spacious but tonal balance seems the same at first blush. I wanted to try some movies but there's no sound from lossless audio tracks.
I struggled w/no sound the first time I set things up, but I can't seem to klutz my way out of it this time.
HDMI audio is Off in System Setup
HDMI cable from Bluray player is plugged into HDMI 1.
Input settings for Video 1:
HDMI Assign HDMI 1
Video Assign Component 1
Video Mode HDMI
Audio Assign Optical 1 (I get sound for the parts of the DVD that aren't in lossless)
Audio Mode I tried both HDMI and Auto, no luck
In sound parameters I tried Dolby TrueHD both On and Auto
The HDMI light on the front panel isn't blinking.
Some general comments:
The manual sucks. Disorganized, and when you do find the topic you're looking for, it's cryptic and not very helpful.
I find it very irksome that the tone controls are not available w/Trinnov on.
I believe imaging cues are concentrated between 2 and 3 kHz, so I can't see any harm to Trinnov's space control by having some control outside that range.
Even if there were, the user should be able to make their own choice between spacial characteristics and tonal balance if that's what it comes down to.
Re bass, the trouble w/just changing the sub's level is that it doesn't raise the level of bass instruments' harmonics, so it can end up sounding thick and inarticulate.
Ideally there would be a tilt control like Lexicon's, but enabling the tone controls would help a lot.
1) Trinnov and surround modes - as far as I can tell Trinnov disables all others; correct?
2) The surround button next to the Standby switch - the display indicates that it turns Trinnov on and off; it toggles between saying "Trinnov Surrou" (no surround modes can be selected) and whatever the last selected surround mode was, and it can be changed. I was surprised today that when I turned it off that the rotated soundstage I had set up stayed rotated.
So just what is that button supposed to do?
3) Why does the front panel have two different indicators saying V.UPSCALE and Video Scaling when I set scaling to Bypass in the menus?
