7. D-RANGE (Adjusting the dynamic
range)
Choices: MAX/STD (Standard)/MIN
Preset position: MAX
Note
• This adjustment is only effective when Dolby Digital is being
decoded.
“Dynamic range” is the difference between the maximum
level and the minimum level of sounds. Sounds on a movie
originally designed for movie theaters feature a very wide
dynamic range. Dolby Digital technology can modify the
original sound track into a home audio format with this
wide dynamic range unchanged. Powerful sounds of
extremely wide dynamic range are not always suitable for
home use. Depending on the condition of your listening
environment, it may not be possible to increase the sound
output to a level as high as that in a movie theater. However,
at the normal level suitable for listening in your room, the
low-level parts of source sound often cannot be heard well
because they will be lost among noise in your environment.
Dolby Digital technology has also made it possible to
reduce an original sound track’s dynamic range for a home
audio format by “compressing” the sound data.
MAX
In this position, a source encoded with Dolby Digital is
reproduced in the original sound track’s wide dynamic
range to provide you with powerful sounds just like those in
a movie theater. Selecting this position will be even better if
you can listen to a source at a high output level in a room
specially soundproofed for audio/video enjoyment.
STD (Standard)
In this position, a source encoded with Dolby Digital is
reproduced in the “compressed” dynamic range of the
source that is suitable for low-level listening.
MIN
In this position, the dynamic range is more reduced than in
the STD position. Selecting this position will be effective
when you must listen to a source at a low level.
Note
• It may happen that sound is output faintly or not output normally
depending on the source. In that case, select the MAX or STD
position.
5. MAIN LVL
Choices: NORM (Normal)/–10 dB
Preset position: NORM (Normal)
NORM (Normal)
Normally select this position.
–10 dB
Select this position if the sound output from the main
speakers is too loud and cannot be balanced with the sound
output from the center and rear speakers. In this position,
the sound output from the main speakers is attenuated.
Notes
• The setting of “CENTER SP”, “REAR SP”, “MAIN SP” and
“BASS OUT” have no effect on a source connected to the
EXTERNAL DECODER INPUT terminals on the rear of this
unit.
• Once you have adjusted appropriately for “CENTER SP”, “REAR
SP”, “MAIN SP”, “BASS OUT” and “MAIN LVL”, you do not
have to change any settings unless your speaker system is
modified.
6. D.D. LFE (Adjusting the output
level of the LFE channel for Dolby
Digital)
Control range: –20 dB to 0 dB (in 1 dB steps)
Preset value: 0 dB
Note
• This adjustment is only effective when Dolby Digital is being
decoded and the selected source encoded with Dolby Digital
contains LFE signals.
This adjusts the output level of the LFE channel. If the LFE
signals are mixed with signals of other channels and they
are directed to the same speakers, the ratio of the LFE signal
level to the level of the other signals can be adjusted.
