Wide:

Select if the listening angle is 40 degrees.

`

Narrow:

Select if the listening angle is 20 degrees.

With this setting, you can optimize the Theater-
Dimensional listening mode by specifying the angle of the 
front left and right speakers relative to the listening 
position. Ideally, the front left and right speakers should 
be equidistant from the listening position and at an angle 
close to one of the two available settings.

• When “Audyssey Quick Start” has been used for measurement, 

the “Audyssey” cannot be selected.

• Audyssey equalizing does not work for DSD sources.
• 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, or
– the USB input selector is selected.

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.

• 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, or
– the USB input selector is selected.

`

0 dB:

It should be used when listening to movies.

`

5 dB:

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. 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. 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.

• If  “Dynamic EQ” setting is set to “Off”, these technologies 

cannot be used.
