I have a heavily treated room and want access to the Audyssey Flat curve as a result. I have an Integra DHC-9.9.
On AVS, there has been significant discussion about how to get access to the Audyssey Flat curve rather than the standard roll-off.
On the Onkyo/Integra lines there is also a Re-Eq button, that applies to most (perhaps all) modes, including Dolby (DD EX, DPLIIx, TrueHD) and DTS (Neo:6, DTS HD MA, etc).
In the THX modes, the my 9.9 shows "Re-Eq (THX)" which seems to indicate the THX Re-Eq rolloff.
The manual states the Re-Eq button "can compensate a soundtrack whose high-frequency content is too harsh, making it more suitable for home theater viewing." - the standard description for HF roll-off. I assumed this meant the Re-Eq button was a Onkyo roll-off curve for non-THX modes.
Could you please clarify
1. if the Re-Eq button activates a proprietary roll-off curve (or not) for non-THX modes
2. how the Re-Eq button interacts with the Audyssey MultEq XT curve when Audyssey is active and Re-Eq is switched On/Off
3. how specifically you can get the Audyssey flat curve on the Onkyo line (DHC-9.9 to be precise)? Is a THX mode with THX Re-Eq disabled the only way, or can you get to it in standard DD & DTS modes?
