Panorama
The location of the front speakers and the listening position are crucial to
Panorama’s effectiveness and for best results your system and the CP-1
together should be set up and calibrated according to the procedure on page
10. The strength of the Panorama effect drops off as you move away from
the prime listening position, especially to the sides. Video systems with the
main loudspeakers spaced closely on either side of a TV screen will produce
a diminished effect over a somewhat wider area than set-ups with a large
included angle between the speakers. Note
* 0 in BINAURAL, or if no rear speakers specified
Program
Parameters
Panorama extracts the natural ambience from recorded music and moves it
outward from the speakers, producing greater width and depth of image
and a feeling of enhanced spaciousness. The program adds no additional
sound but expands the existing stereo image. Panorama also works with
Dolby Stereo movies, bringing the surround track outward into the room.
Panorama works with just two loudspeakers. If side speakers present,
Panorama disables them and substitutes its own simulation. The front
speakers are driven entirely from the CP-1’s digital circuits. Panorama will
also send a stereo difference signal (left channel minus right or vice-versa)
to the rear loudspeakers if you have them. NORMAL (1) will provide
enough expansion for most music, while WIDE (2) has a more pronounced
effect on the image. BINAURAL (3) has special low-frequency compensa-
tion and is meant specifically for true binaural recordings made with a
dummy head.
Panorama NORMAL is designed to work with recordings whose bass
energy is evenly distributed across the stereo image. Panorama WIDE is
designed for recordings with centered bass (almost all pop and rock). The
only other difference between these two programs is their initial EFFECT
LEVEL. If you need more bass from Panorama NORMAL, switch to WIDE
and reduce the EFFECT LEVEL. Conversely, if Panorama WIDE is too bass-
heavy, switch to NORMAL and increase the EFFECT LEVEL.
