EFFECT LEVEL controls the loudness of the center, side and rear outputs.
SIDE EFFECT controls the volume level of the side speakers. Since Music
Logic is a dynamic ambience extraction mode, the effect of the side speakers
will depend on the recording. Although the default value is 0, the correct
setting will vary with each recording, your room, and your personal taste.
SIDE ROLLOFF sets the frequency above which the side channel sound is
attenuated. REAR ROLLOFF sets the frequency above which the rear
channel sound is attenuated. These controls should be high enough to give
presence and airiness to the side and rear sound, but not so high as to enable
you to localize distracting instrumental overtones or other sounds from the
sides or rear. The appropriate setting will vary with program material.
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-1 does not have or need an
input balance control for Dolby Surround decoding.
REAR DELAY Since the rear channel in Music contains extracted ambient
information, it typically does not need as much delay as the film surround
modes. This delay can be adjusted between 0-30 milliseconds. It should not
be set so high as to create a distinct echo in the rear.
The procedures for naming a new version of the program (SET PROGRAM
NAME) and storing it in one of the User registers (MEMORIZE PROGRAM)
are described on page 36.
