MC-12

MODE ADJUST

BASS ENHANCE ON, OFF

Selecting the ON setting enhances stereo bass, which results in low-frequency reproduction that is less localizable and more realistic in the listening space. The effectiveness of the BASS ENHANCE parameter varies depending on room acoustics and the ability of the surround speakers to reproduce low frequencies. It is recommended to use front, side, or rear speakers that are capable of reproducing frequencies of 40Hz or lower.

Note:

When the BASS ENHANCE parameter is set to ON, most listening spaces have a 2 to 3dB reduction in low-frequency energy. Set the AUDIO CONTROLS menu BASS parameter to compensate for this reduction.

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. The full parameter range might not be available depending on the MID RT and SIZE parameter settings.

CAUTION Setting the BASS RT, MID RT, or SIZE parameters to a high value may produce undesirable or damaging audio.

CALIBRATION

Opens the PANORAMA CALIBRATION menu, which can be used to calibrate the PANORAMA listening mode. Refer to page 5-12 for more information.

CENTER OFF, -30 to +12dB

Controls the output level of the Main Zone 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 primary listening position.

CENTER MIX -25 to +5dB

Indicates the relative center channel level for downmixing. It is recommended to 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. It is recommended to 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 sources. When ON is selected, full compression is applied regardless of volume level. When OFF is selected, compression is not applied. It is recommended to set this parameter to AUTO or ON for Dolby Digital sources that are listened to at lower volume levels, especially for nighttime viewing to avoid disturbing others.
