Surround Mode Descriptions
Each of the available Surround modes is described below. The table
included with each description indicates the corresponding Surround
mode parameters, their factory default settings, and all the possible
parameter settings. Surround modes that have no adjustable parameters
are indicated as such in the description.
For explanations of the individual Surround mode parameters, refer to the
“Surround Mode Parameter Descriptions” section found later in this
chapter.
Logic 7
The Logic 7 mode is an advanced mode that extracts the maximum sound
information from either surround-encoded programs or conventional
stereo material. These surround modes can derive up to 7.1-channels of
surround sound from a 2-channel or 5-channel input source. The Logic 7
mode provides full-frequency stereo surround channels that realistically
increase the perceived width, length, and sense of envelopment of the
listening space.
The Logic 7 mode also has additional bass-enhancement capability that
circulates low frequencies in the 40Hz to 120Hz range to the front and
surround speakers. This creates a soundstage that is broader and wider
than when the subwoofers are the sole source of bass energy. This
additional bass enhancement feature can be turned On or Off.
L7 Film (Logic 7 Film)
This Surround mode is designed for enhanced playback of 2-channel
stereo, multi-channel, or matrix-encoded film sources. Use this mode
with any source that contains Dolby Surround, DTS:Neo6, or similar
matrix-encoding to experience increased center channel intelligibility
and more accurate placement of sounds.
