EFFECT LEVEL controls the loudness of the front, side and rear outputs.
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 does not have or need 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.
SIDE SPEAKER ASSIGN determines whether the information fed to the
side outputs is derived from the front left and right, or from the rear.
Choosing the front setting will create a very wide soundstage, which can be
very exciting on some soundtracks. On others, particularly those with
panned dialog and very tight localization of sound effects, the soundstage
will be too wide. Technically, the rear setting is a closer match to the original
recording format.
In Pro Logic, MAIN MUTE mutes the center output; EFFECTS MUTE mutes
the front, side and rear outputs.
