SURROUND EFFECT The Stereophonic setting provides extraction of five
channels of surround information from a standard 4-2-4 matrix-encoded
soundtrack (Dolby Surround, Ultra*Stereo, etc.) The drama of this effect is
dependent on the source material, and will be most noticeable with strong
stereo music soundtracks. The Decorrelate setting electronically
"scrambles" the monaural surround channel to provide added spaciousness
and envelopment.
The RE-EQUALIZER equalizes the left, center and right channel outputs to
match the overall frequency balance of the original recording. Without this
re-equalization, many films, and some television programs, will sound too
bright and become fatiguing to listen to.
The AUTO AZIMUTH/BAL (short for Auto Azimuth Error Correction/
Automatic Input Balance) parameter should be set to ON for films, OFF for
music. When it is 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 why the CP-3
an input balance control for Dolby Surround decoding.
BASS SPLIT takes the low bass from the center, where it is in many film and
music mixes, and distributes it instead to the left and right front-channel
speakers. Bass Splitting is valuable because in many video installations the
center speaker is smaller than the two main stereo speakers and is less
capable of handling the lowest frequencies. By directing the low frequencies
to the main speakers, there is less risk of damage to a small center speaker
and no loss of bass information since it will be reproduced by the main
speakers.
SUB BASS BOOST boosts or cuts the subwoofer output level. Although the
normal subwoofer level was set during the initial calibration procedure,
with some recordings you may find it desireable to increase or decrease this
deep bass level.
In THX, MAIN MUTE mutes the center output; EFFECTS MUTE mutes the
front, side and rear outputs.
