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.

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 pro-
gram material that is mixed at very high listening
levels and has a compressed dynamic range.

Movies are mixed in rooms calibrated for film refer-
ence. To achieve the same reference level in a home the-
ater 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 cali-
brated by Audyssey MultEQ

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 mix-
ers heard it.
Audyssey Dynamic EQ is referenced to the standard
film mix level. It makes adjustments to maintain the ref-
erence response and surround envelopment when the
volume is turned down from 0 dB. However, film refer-
ence 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 setting cannot be

selected.

Dynamic Volume

Off:

Audyssey Dynamic Volume

off.

Light:

Light Compression Mode becomes active.

Medium:

Medium Compression Mode becomes active.

Heavy:

Heavy Compression Mode becomes active. This set-
ting affects volume the most, causing all sounds to
be of equal loudness.

Note

• Even if you have selected other than “Audyssey” in “Equalizer”

setting after performing Audyssey MultEQ Room Correction
and Speaker Setup, selecting “On” in the “Dynamic EQ” will
change the “Equalizer” setting to “Audyssey” (

➔

47).

• If you would like to use Audyssey Dynamic Volume, when

using THX listening modes, set “Loudness Plus” setting to
“Off” and set “Preserve THX Settings” setting to “No” (

➔

48).

• When “Dynamic Volume” is set to effective, “Equalizer” is set

to “Audyssey” (

➔

47) and “Dynamic EQ” is set to “On”.

When “Dynamic EQ” is set to “Off”, “Dynamic Volume”
becomes “Off” automatically.

• When “Dynamic Volume” is set to effective, the Dynamic Vol

indicator will light (

➔

9).

• If Pure Audio or Direct listening mode is selected, this setting

cannot be selected.

Audyssey MultEQ then removes the distortion caused by
room acoustics by capturing room acoustical problems
over the listening area in both the frequency and time
domain. The result is clear, well-balanced sound for every-
one. Enabling Audyssey MultEQ allows you to also use
Audyssey Dynamic EQ, which maintains the proper
octave-to-octave balance at any volume level.
Before using this function, connect and position all of
your speakers.

About Audyssey Dynamic EQ
Audyssey Dynamic EQ solves the problem of deterio-
rating 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 con-
stant despite changes in volume. Dynamic EQ combines
information from incoming source levels with actual
output sound levels in the room, a prerequisite for deliv-
ering a loudness correction solution.
Audyssey Dynamic EQ works in tandem with
Audyssey MultEQ 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. When-
ever 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.
