CP-1 Digital Audio Environment Processor
If your main interest is music, you will most likely begin with two high-
quality main speakers (Configuration 1). Here the Panorama program
alone will add substantial enhancement in spatial impression, image size,
image depth and freedom from coloration of central sources.
The audiophile's first addition should be two side channels (Configuration
5) and, after that, two rear channels (Configuration 9). For maximum effect
with the Reverberation programs, two additional speakers can be placed in
the front corners of the room, driven from the rear amplifiers. The side
speakers, however, are the most important.
With Configuration 5, movies can be played with the Pro Logic program;
the rear-channel sound will automatically be routed to the side speakers. If
you have six speakers (Configuration 9) an additional stereo amplifier can
power both a center channel and a subwoofer.
The height of the extra speakers will depend on the furnishings in the room.
In real halls much of the reflected energy comes from above, and placing the
side and rear speakers above the listener can be very effective. They also
work well on normal speaker stands. Placing the speakers too high in a
narrow room may reduce the spaciousness, since this makes the sound
come from the ceiling instead of the side walls.
The Subwoofer Output is a monaural signal created by summing the left,
right and center outputs, then filtering out frequencies above 100 Hz at a
rate of 12 dB per octave.
Connecting a subwoofer to the CP-1 rear-panel Subwoofer Output, adds
bass energy without removing any from your main speakers. Note, how-
ever, that many of the subwoofers curently on the market have their own
crossover built in, and in some cases it cannot be adjusted or defeated. These
are generally designed to generate the deep bass for your system in order
to relieve your main speakers and amplifier from having to produce these
low frequencies. To take advantage of this, connect the CP-1 Main Outputs
to the subwoofer crossover input and connect the front main amplifier to the
high pass output from the subwoofer. Because the CP-1 has some parame-
ters specifically dedicated to low frequency processing, we recommend
inserting a crossover ( or any other signal processor) after the CP-1 in the
signal chain.
