CATHEDRAL
The CATHEDRAL mode is similar to the CHURCH listening mode. It
uses a reverb algorithm to emphasize the rich, smooth, reverberant
decay characteristic of large listening spaces with long reverber-
ation time relative to their size, such as cathedrals.
The CATHEDRAL mode is a superior room simulation listening
mode because it uses a proprietary reverb algorithm that is relied
upon by a majority of recording engineers to add ambience to
recordings.
* BASS RT, MID RT, and SIZE parameter settings are interdependent, meaning that the
full parameter range might not be available depending on the other parameter settings.
See page 5-35 for detailed parameter descriptions.
PANORAMA
The PANORAMA mode is designed for playback of stereo and
matrix encoded sources. PANORAMA uses proprietary Lexicon
algorithms to move the stereo image outward from the front
speakers, producing a wider stereo field with greater depth.
Sound quality depends on proper location of the listening position
and front speakers. When the front speakers are positioned close to
either side of the display device, the effect is produced over a wider
area than when the front speakers are positioned at a large angle
from the display device.
See page 5-35 for detailed parameter descriptions.
