The CP-1's Configuration routine allows a wide range of choices in speaker
and room set-ups to maintain optimal performance as your system ex-
pands. If you are starting with a conventional two-channel system, in what
order should you add additional channels? The answer depends on
whether you are primarily interested in audio or video.
The film enthusiast with only two stereo speakers should place them
relatively close on either side of the screen and use Panorama for both music
and films. Beyond this, the very first priority should be a center channel
above or below the screen for dialog (Configuration 2). An alternative is
Configuration 3, in which two front speakers and one rear are used with
either the Panorama or Pro Logic programs.
A dramatic improvement will be noticed when increasing from two or three
speakers to four. These should be arranged as in Configuration 6, but with
the front left and right speakers spread quite wide, perhaps all the way
around to the sides — making a diamond pattern with the listener in the
center. How widely you space the front channels will depend on how
deeply immersed in the sound track you want to be; the full diamond
configuration can considerably heighten the sense of emotional involve-
ment in many movies. This arrangement has the advantage of using
amplifiers and speakers in pairs.
If your center channel speaker is smaller than the left and right fronts,
increasing BASS BLEND will remove low bass from the center and increase
it in the left and right speakers. The center channel is so important that if it
is not possible to have an extra center speaker it is frequently better to plug
the center output of the CP-1 into the audio input of your video monitor and
use its built-in speaker (if it has one) than it is to run the dialog through the
main loudspeakers.
The best set-up for those who like both music and films is Configuration 10.
The addition of side speakers allows all forms of source material to be
palyed without compromise.
The button on the back of the CP-1 labeled CENTER OUT/PHANTOM
IN is very important in the operation of the Surround programs. Make
sure the button is out if you have a center speaker and in if you have none.
With the button in (Phantom Mode) the center channel is mixed in with
the two main outputs; the side outputs carry the Left and Right signals;
the center channel is turned off.
