AV1 Mode Adjust
5-29
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 AV1 provides an increased sense of spacious-
ness 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 effec-
tiveness 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 AV1 con-
tinually 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 maxi-
mum separation. When set to OFF, the accuracy of the selected lis-
tening 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.
BASS CONTENT BINAURL, MONO, STEREO
Adjusts the bass content of binaural, mono and stereo recordings.
When set to BINAURL, the AV1 activates low-frequency compensa-
tion. 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 repro-
duce 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.
CAUTION!
When set to ON, the BASS ENHANCE parameter might damage
speakers that are not capable of producing low frequencies
below 80Hz.
