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-8 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 to 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-8
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
to set this parameter to ON for film and broadcast sources and to
OFF for music sources.
BASS CONTENT
BINAURL, MONO, STEREO
Adjusts the bass content of binaural, mono, and stereo recordings.
When set to BINAURL, the MC-8 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 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. It is recommended to use the
AUDIO CONTROLS menu BASS parameter to com-
pensate for this reduction.
When set to ON, the BASS ENHANCE parameter might
damage speakers that are not capable of producing low
frequencies below 80Hz.
