Insignia NS-HTIB51A 5.1 Channel Home Theater System
www.insigniaproducts.com
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
plays 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.
Note
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 in tandem with
Audyssey 2EQ 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.
Adjusting the Theater-Dimensional setting (Listening
Angle submenu)
This setting lets you 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.
Naming inputs (Name Edit menu)
You can enter a preset name for each individual
input selector for easy identification. When entered,
the preset name appears on the display.
Before selecting a name, press the input selector to
select the input source to name.
Submenu Configuration
Audyssey
Off–No Audyssey 2EQ equalizing is applied.
On–Dynamic EQ and Dynamic Volume become
available. The Audyssey indicator lights.
Dynamic EQ
Off (default)–Audyssey Dynamic EQ off.
On–Audyssey Dynamic EQ on. The Dynamic EQ
indicator lights.
Reference Level
0 dB (default)–Use 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.
Dynamic Volume
Off (default)–Audyssey 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 the most, causing all
sounds to be of equal loudness.
Notes
• The setting is stored individually for each input
selector. If you make Dynamic Volume™ active,
Audyssey and Dynamic EQ settings are set to
On. The Dynamic Vol indicator lights.
