■ 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 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”, 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 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”.
• These technologies cannot be used when:
– a pair of headphones is connected, or
– Direct listening mode is selected.
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 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.
