I'm very curious about the new firmware! Anyone brave enough to try?
I have a question about Re-EQ as well, hoping you guys know how it works (my underline below).
First post, bottom:
High frequency roll-off with THX Re-EQ and/or Audyssey
The Audyssey target frequency curve is flat in the bass with a slight roll-off in the high frequencies.
The roll-off is not based on the type of content. It takes several factors into account including: (i) the difference in listening conditions that exist in the mixing environment and the home; (ii) the changes in speaker directivity that occur at higher frequencies, which affect the balance of direct and reverberant sound. Both of the above apply to movie and most properly produced TV content.
Caveat: If you use the Audyssey Reference Curve and THX Re-EQ then you will have double the roll off in the high frequencies.
There is no way to manually select Audyssey Reference Curve or Audyssey Flat except by using a THX listening mode.
Listening modes are either:
a) modes that use the Audyssey Flat Curve and THX Re-Eq can be 'On' or 'Off'.
b) modes that use the Audyssey Flat Curve and THX Re-Eq can not be applied.
c) modes that use the Audyssey Reference Curve and THX Re-Eq can be 'On' or 'Off'.
d) modes that use the Audyssey Reference Curve and THX Re-Eq can not be applied.
Basically, anything with 'THX' is either a) or b):
Anything with 'THX' combined with 'Cinema' or 'EX' fell into a).
Anything with 'THX' combined with 'Music' or 'Games' fell into b).
The listening modes were you can end up with double high frequency roll off from Audyssey Reference curve
combined with 'THX Re-Eq: On', category c), were:
- DTS Neo 6
- Dolby Prologic IIx Movie
- Dolby Digital EX
- Neural THX 7.1
- Dolby Digital
I sure wouldn't like ending up with double high roll off while playing DD content in TXX cinema mode. After some searching I found this: (first post "Official" Audyssey thread, about in the middle)
2. Re-Equalization technologies affect the target curve selection.
a. One component of THX is called Re-EQ, which applies a high frequency shelf cut filter. When listening in THX mode with Re-EQ on, it is recommended to use the Audyssey Flat target curve.
[cut some text here]
3. The selection of Audyssey target curves is performed manually in some products (e.g. Denon, NAD, Marantz) and automatically in others (e.g., Onkyo).
a. For products with manual selection follow the guidelines above.
b. For products with automatic selection, the following rules apply:
i. The Audyssey or Audyssey Reference target curve is selected after calibration.
ii. The Audyssey Flat target curve is selected automatically when you switch to a THX listening mode.
Does the target curve really change to flat automatically when Re-EQ is enabled? I can't confirm it in a the audio/Audyssey menu because the DD stream stops a s soon as I enter the menu. One solution would be to turn RE-EQ off permanently and always use Audysseys roll off in the reference target curve -- problem is I can't. Re-Eq is always enabled next time I power on the receiver and enter a THX mode. Also, I can't change the target curve to flat manually (in setup/audio/Audyssey) - it is grayed out in reference mode.
Thanks for any input regarding this.
Oh, and the firmware is a *really* slow download! Getting 4 KB/Sec
