I redid my measurements of a 16kHz test signal, this time with my Onkyo TX-NR3007 and placing the SPL meter close to tweeter of my front right speaker.
The previous time I had it placed at the first measurement position done with Audyssey.
So the 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 Re-Eq can be 'On' or 'Off'.
d) modes that use the Audyssey Reference Curve and 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 'Re-Eq: On', category c), are:
- DTS Neo 6
- Dolby Prologic IIx Movie
- Dolby Digital EX
- Dolby Digital
- Neural Surround
This picture shows my test readings with a SPL meter and a 16Khz Dolby Digital test tone.
The Stereo value was measured with an analog signal. I calculated the value relatively
to Dolby Prologic IIx Movie which I also enabled with the analog signal as well
as the 16khz signal.
Please note that the listening mode categories are just me guessing based
on the measured SPL readings.
