LISTENING MODE MENU OPTION & PARAMETER DESCRIPTIONS (continued)
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.
CAUTION!
Setting the BASS RT, MID RT and SIZE parameters to a high
value may produce undesirable or damaging audio.
CALIBRATION
Opens the PANORAMA listening mode CALIBRATION menu, which
is used to calibrate the PANORAMA listening mode. Refer to page
“PANORAMA CALIBRATION” on page 5-12 for more information.
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 set-
tings 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. Set this
parameter to +0dB for film sources and -5dB for music sources.
CNTR DLY SAMPLES -127 to +127
Controls the relative time offset of the center channel. 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 intelligibility
at lower listening levels for Dolby Digital input sources. When ON, full
compression is applied regardless of volume level. When OFF, com-
pression is not applied. Set this parameter to AUTO or ON for Dolby
Digital input sources that are listened to at lower volume levels, espe-
cially 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 as a “phantom” center image from the front left and right
speakers. When set on the 1 to 6 scale, the center image is heard in
various combinations of the front and center speakers.
CUSTOM
Opens the CUSTOM menu, which is used to compare custom and fac-
tory-default versions of the selected listening mode and to restore the
factory default version of the selected listening mode.
