PCM Effects and Parameters
speakers are used for bass enhancement, the effectiveness is improved
with speakers capable of reproducing reproducing low frequencies
(LARGE). Using speakers that are not capable of producing low
frequencies (<80Hz) may cause damage to them.
BASS RT (low frequency reverberation time) depends on MID RT and
is expressed as a multiplier. BASS RT should be set to 1.0 x MID RT for
a more natural effect in smaller spaces.
CENTER LEVEL adjusts the output level from the center speaker.
EFFECT LEVEL adjusts the loudness of the side and rear speakers.
When there are no side speakers, it adjusts the amount of ambient
signal mixed into the main loudspeakers. In Panorama, this control
changes the apparent width of the front soundstage. 0 = ordinary stereo,
62 provides the widest image.
FRONT STEERING provides three basic settings which have been
developed specifically to optimize center channel signal strength for film
and music.
The FILM setting has excellent frontal image stability through the whole
room during dialog and vocals, while preserving the full width of the front
image in the spaces between dialog, and for music without vocals. The
front image during vocals is noticeably narrower than with the MUSIC
setting, but highly satisfactory nonetheless.
The MUSIC setting reproduces sound in all three front speakers when
a strongly centered, or mono signal is present. This is an excellent
choice for heavily centered pop music such as metal and sounds more
natural for broadcast material with a single announcer. OFF sets the
center channel level to 4.5dB less than the front left and right speakers,
and then leaves the level unchanged as the steering varies. This setting
is equivalent to conventional stereo with a slight center fill.
HALL SIZE allows you to select room sizes of lengths ranging from 4-
38 meters, depending on the effect selected.
INPUT BALANCE allows you to compensate for the occasional source
with audible channel imbalance. When selected, screen graphics
indicate the relative left/right position.
LIVENESS adjusts the amount of recirculation within the effect. Higher
values mimic more reflective surfaces in the simulated space and
increase the amount of time it takes the sound to decay. At very high
values, the decay is audibly less smooth than in the Church and
Cathedral Effects, which are more effective at simulating very live
spaces.
