FILM EQ equalizes the left, center and right channel outputs to match the
overall frequency balance of the original recording. Without this equaliza-
tion, many films, and some television programs, will sound too bright and
become fatiguing to listen to.
The AUTO AZIMUTH/BAL parameter should be set to ON for films, OFF
for music. When it is on, special digital circuits continually monitor the
dialog and adjust both the relative level and time offset of the two channels
to keep the dialog properly centered. This automatic feature is why the CP-
1 does not have or need a front-panel 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-channels
and the subwoofer. This is valuable because in many video installations the
center speaker is smaller than the two main stereo speakers and is, therefore,
less capable of handling the lowest frequencies. Refer to the graph on page
31.
REAR DELAY in Pro Logic is adjustable. Generally, the correct delay is
about 20 milliseconds but the setting depends on speaker set-up and source
material. In general, the delay should not be so great that the rear sound
becomes identifiable as a distinct source.
The SIDE SPEAKERS control turns the side speaker output on or off,
widening or reducing the apparent stereo spread.
The CALIBRATE mode in Stereo Logic and Pro Logic is for setting up and
checking the levels of the channels in multi-speaker systems. Its use is
covered in the section on Balancing Additional Channels on page 12.
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.
