MODE ADJUST
MC-4
5-29
BASS CONTENT BINAURL, MONO, STEREO
Adjusts the bass content of binaural, mono and stereo recordings.
When set to BINAURL, the MC-4 activates low-frequency
compensation. Select this setting for true binaural sources
recorded with dummy head microphones. Select the MONO
setting for sources recorded with mono bass. Select the STEREO
setting for sources recorded with stereo bass.
BASS ENHANCE ON, OFF
Enhances stereo bass, which results in low-frequency reproduc-
tion 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 that
you 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 2dB to 3dB reduction
in low-frequency energy. It is recommended that you
use the AUDIO CONTROLS menu BASS parameter
to compensate for this reduction.
LISTENING MODE MENU OPTION & PARAMETER
DESCRIPTIONS
5 SPKR ENHANCE
ON, OFF
Simulates 7-channel playback in 5-channel speaker configurations.
When set to ON, the MC-4 provides an increased sense of
spaciousness and envelopment through the surround speakers.
This enhancement is most noticeable when the surround speakers
are positioned to the side of the primary listening position or
when the primary listening position is located against the rear
wall. The effectiveness of this parameter varies within the listening
space. For best results, it is recommended that you position the
surround speakers to the left and right sides of the primary
listening position.
ACADEMY FILTER ON, OFF
When set to ON, restores the proper tonal balance of older mono
film sources that have much narrower frequency responses than
more recent mono film sources.
AUTO AZIMUTH ON, OFF
Maximizes matrix steering accuracy. When set to ON, the MC-4
continually monitors the 2-channel input signal and automatically
adjusts the relative level and time offset of the input channels to
ensure that signals are sent to the appropriate channels with
maximum separation. When set to OFF, the accuracy of the
selected listening mode varies among sources. It is recommended
that you set this parameter to ON for film and broadcast sources
and to OFF for music sources.
When set to ON, the BASS ENHANCE parameter might
damage speakers that are not capable of producing low
frequencies below 80Hz.
