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 5-12for more information.

CENTER			OFF, -30dB to +12dB
MODE ADJUST	(Listening Mode)	OUTPUT LEVELS		CENTER

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

MODE ADJUST (Listening Mode) 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.
