Listening Angle
`
Wide
:
Select if the listening angle is 40 degrees.
`
Narrow
:
Select if the listening angle is 20 degrees.
With this setting, you can optimize the Theater-
Dimensional listening mode by specifying the angle of the
front left and right speakers relative to the listening
position. Ideally, the front left and right speakers should
be equidistant from the listening position and at an angle
close to one of the two available settings.

With Audyssey Dynamic EQ, you can enjoy great sound
even when listening at low volume levels.
Audyssey Dynamic EQ solves the problem of
deteriorating sound quality as volume is decreased by
taking into account human perception and room acoustics.
It does so by selecting the correct frequency response and
surround volume levels moment-by-moment so that the
content sounds the way it was created at any volume level
— not just at reference level.
Note
• These technologies cannot be used when:
– a pair of headphones is connected, or
– either Pure Audio or Direct listening mode is selected.

Reference Level
Audyssey Dynamic EQ Reference Level Offset
`
0 dB
:
It should be used when listening to movies.
`
5 dB
:
Select this setting for content that has a very wide
dynamic range, such as classical music.
`
10 dB
:
Select this setting for jazz or other music that has a
wider dynamic range. This setting should also be
selected for TV content as that is usually mixed at
10 dB below film reference.
`
15 dB
:
Select this setting for pop/rock music or other
program material that is mixed at very high listening
levels and has a compressed dynamic range.
Movies are mixed in rooms calibrated for film reference.
To achieve the same reference level in a home theater
system each speaker level must be adjusted so that
–30 dBFS band-limited (500 Hz to 2000 Hz) pink noise
produces 75 dB sound pressure level at the listening
position. A home theater system automatically calibrated
by Audyssey 2EQ will play at reference level when the
master volume control is set to the 0 dB position. At that
level you can hear the mix as the mixers heard it.
Audyssey Dynamic EQ is referenced to the standard film
mix level. It makes adjustments to maintain the reference
response and surround envelopment when the volume is
turned down from 0 dB. However, film reference level is
not always used in music or other non-film content. The
Dynamic EQ Reference Level Offset provides three
offsets from the film level reference (5 dB, 10 dB, and
15 dB) that can be selected when the mix level of the
content is not within the standard.
Note
• If “
Dynamic EQ
” setting is set to “
Off
”, these technologies
cannot be used.
