Audyssey Dynamic EQ ® becomes active.
The Dynamic EQ indicator lights.
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.

Reference Level
Audyssey Dynamic EQ Reference Level Offset
`
0dB:
This should be used when listening to movies.
`
5dB:
Select this setting for content that has a very wide
dynamic range, such as classical music.
`
10dB:
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.
`
15dB:
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 MultEQ
® XT32
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. Audyssey 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.

Dynamic Volume
`
Off
`
Light:
Activates Light Compression Mode.
`
Medium:
Activates Medium Compression Mode.
`
Heavy:
Activates Heavy Compression Mode. This setting
affects volume the most. It quiets the loud parts,
such as explosions, and boosts the quiet parts so they
can be heard.
Note
• If you want to use Audyssey Dynamic EQ or
Audyssey Dynamic Volume ® with THX listening modes, set
the “Loudness Plus” setting to “Off” and set “Preserve THX
Settings” to “No” (
➔ page 55
).
• If you make Dynamic Volume active, “Dynamic EQ” is set to
“On”. The Dynamic Vol indicator will light.
• When “Dynamic EQ” is set to “Off”, “Dynamic Volume” is
automatically switched to “Off”.
About Audyssey Dynamic EQ ®
Audyssey Dynamic EQ solves the problem of
deteriorating sound quality as volume is decreased by
taking into account human perception and room
acoustics. Dynamic EQ selects the correct frequency
response and surround levels moment-by-moment at
any user-selected volume setting. The result is bass
response, tonal balance and surround impression that
remain constant despite changes in volume. Dynamic
EQ combines information from incoming source levels
with actual output sound levels in the room, a
prerequisite for delivering a loudness correction
solution.
About Audyssey Dynamic Volume ®
Audyssey Dynamic Volume solves the problem of large
variations in volume level between television programs,
commercials, and between the soft and loud passages of
movies. Dynamic Volume looks at the preferred volume
setting by the user and then monitors how the volume of
program material is being perceived by listeners in real
time to decide whether an adjustment is needed.
Whenever necessary, Dynamic Volume makes the
necessary rapid or gradual adjustments to maintain the
desired playback volume level while optimizing the
dynamic range. Audyssey Dynamic EQ is integrated
into Dynamic Volume so that as the playback volume is
adjusted automatically, the perceived bass response,
tonal balance, surround impression and dialog clarity
remain the same whether watching movies, flipping
between television channels or changing from stereo to
surround sound content.
