SDP-40HD Mode Adjust
5-35
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 SDP-40HD 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 sides 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, place the surround speakers to the left and right of the primary
listening position. Available in all Logic 7 modes.
ACADEMY FILTER ON, OFF
Restores the proper tonal balance of older mono film sources that have
much narrower frequency responses than more recent mono film
sources. Available in MONO LOGIC and 5.1 MONO LOGIC modes.
AUTO AZIMUTH ON, OFF
Maximizes matrix steering accuracy. When set to ON, the SDP-40HD
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. Set this parameter to ON for film and
broadcast sources and to OFF for music sources. Available in L7 FILM
and L7 TV modes.
BASS CONTENT BINAURAL, MONO, STEREO
Adjusts the bass content of binaural, mono and stereo recordings.
When set to BINAURAL, low frequency compensation is activated.
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. Available in PANORAMA mode.
BASS ENHANCE ON, OFF
Enhances stereo bass, which results in low frequency reproduction
that is less localized 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. For best results, use front, side or rear
speakers that are capable of reproducing frequencies of 40Hz or
lower. Available in all Logic 7 modes.
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. In smaller listening spaces, the BASS RT parameter setting
should match the MID RT parameter setting for more natural effects.
Available in CHURCH and CATHEDRAL modes.
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
“PANORAMA” on page 5-12 for more information. Available in
PANORAMA mode.
