CNTR DLY SAMPLES
–127 to +127
Controls the relative time offset of the center channel. It is
recommended that you set this parameter to +0 unless the center
channel is not properly timed and the value of the error is known.
COMPRESSION
AUTO, ON, OFF
Reduces wide volume level changes and increases dialog intelligi-
bility at lower listening levels for Dolby Digital input sources.
When set to ON, full compression is applied regardless of volume
level. When set to OFF, compression is not applied. It is recom-
mended that you set this parameter to AUTO or ON for Dolby
Digital input sources that are listened to at lower volume levels,
especially for nighttime viewing to avoid disturbing others.
CTR WIDTH
MIN, 1 to 6, MAX
Adjusts the center image. When set to MIN, the center image is
heard from just the center speaker. When set to MAX, the center
image is heard from just the front left and right speakers as a
“phantom” center image. When set on the 1 to 6 scale, the cen-
ter image is heard in various combinations of the front and center
speakers.
CUSTOM
Opens the CUSTOM menu, which can be used to compare cus-
tom and factory-default versions of the selected listening mode
and to restore the factory default version of the selected listening
mode.
CUSTOM (Listening Mode) MODE ADJUST
BASS RT
5ms to 48.6s
Works with the MID RT and SIZE parameters to adjust the
amount of time required for low-frequency information to decay
below 60dB in level. The BASS RT parameter setting should
match the MID RT parameter setting for more natural effects in
smaller listening spaces.
CALIBRATION
Opens the PANORAMA listening mode CALIBRATION menu,
which can be used to calibrate the PANORAMA listening mode.
See “PANORAMA CALIBRATION” on page 5-12 for more informa-
tion.
CENTER
OFF, –30dB to +12dB
Controls the output level of the audio output connector labeled
Center.
CENTER DEPTH
0 to 18
Adjusts the amount of processing applied to the center channel,
changing the perceived distance of the center speaker. Higher
settings increase and lower settings decrease the perceived
distance of the center speaker from the listening position.
CENTER MIX
–25dB to +5dB
Indicates the relative center channel level for downmixing. It is
recommended that you set this parameter to +0dB for film
sources and –5dB for music sources.
CENTER OUTPUT LEVELS (Listening Mode) MODE ADJUST
Setting the BASS RT, MID RT and SIZE parameters to a high
value may produce undesirable or damaging audio.
