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
– Direct listening mode is selected, or
– Speakers B is on, or
– Speakers A is off.
■ Reference Level
Audyssey Dynamic EQ Reference Level Offset
`0dB
:
It should be used when listening to movies.
`5dB:
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.
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.
■ Dynamic Volume
`Off
`Light:
Light Compression Mode becomes active.
`Medium:
Medium Compression Mode becomes active.
`Heavy:
Heavy Compression Mode becomes active. This
setting affects volume 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” setting is
set to “On”. The Dynamic Vol indicator will light (➔ page 8).
• These technologies cannot be used when:
– a pair of headphones is connected, or
– Direct listening mode is selected, or
– Speakers B is on, or
– Speakers A is off.
•When “Dynamic EQ” is set to “Off”, Dynamic Volume”
become “Off” automatically.

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 Volume works fine
by itself, but can also be used with
Audyssey Dynamic EQ. When both are on,
Audyssey Dynamic EQ adjusts the perceived bass
response, tonal balance, surround impression, and
dialog clarity whether watching movies, flipping
between television channels, or changing from stereo to
surround sound content, when Dynamic Volume adjusts
the volume.
