AUTO AZIMUTH is short for auto azimuth error correction/automatic
input balance. Auto Azimuth should be set to ON for films, and OFF for
music. When ON, special patented algorithms continually monitor the
input signal and adjust both the relative level and time offset of the two
channels to keep the dialog properly centered and special effects properly
localized. This automatic feature is the reason the unit does not need an
input balance control for Dolby Surround decoding.
DIALOG ENHANCE boosts dialog in the center channel. By targeting
specific frequencies, it boosts only dialog, without raising the entire center
channel level (which would alter the output balance achieved during
calibration).
FRONT STEERING provides four basic settings which have been devel-
oped specifically to optimize center channel signal strength for film and
music. The MUSIC setting is designed for classical and popular music. It
preserves nearly the full width of the front image, even in complex material
with a high vocal level. At the same time, it reproduces film with plausible
separation between the center speaker and the front speakers during dialog.
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.
1/2 is similar to the MUSIC setting under most conditions, but will repro-
duce 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.
