`On:
Audyssey Dynamic EQ

becomes active.
The Dynamic EQ indicator will light.
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 selected for movie contents.
`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 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.
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”, this technology 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 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.
Audyssey Dynamic EQ works well by itself. However, if
Audyssey 2EQ
®
is on, the two technologies work in
tandem to provide well-balanced sound for every listener
at any volume level.
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.
