The CP-803 has become
the industry standard baseband processor. It is an economical
processor that gives stations a brighter, louder and more
open sound. The CP-803 operates completely differently from
conventional processors in several important ways and also
avoids the distortion produced by baseband clippers.
The CP-803 eliminates
overshoots which exist in all stereo generators and audio
limiters. Preventing overshoots increases modulation while
preserving the integrity of the signal. It also controls
high-frequency peaks present in program material that can
cause over-modulation and thus makes greater average modulation
possible.
The CP-803's patented design deals
with the composite signal that comes from the stereo generator--the
baseband signal. This includes the L+R, L-R and 19 kHz stereo
pilot. By working with this composite signal instead of the
left and right audio other processors deal with, the CP-803
avoids many processing pitfalls.
Thirdly, unlike a distortion-generating
baseband clipper, the CP-803 does not clip the 19 kHz pilot
and will not create the "spectral garbage" or the dynamic
loss of stereo separation that baseband clippers generate.
Because the CP-803 doesn't clip the pilot, stations can increase
signal clipping for extra loudness in competitive markets
without distorting their sound. Many stations--even those
using stereo generators with baseband clippers built-in have
added the CP-803 to their processing chain and increased
clarity, maintained stereo separation and maintained the
loudness desired.
The CP-803 is easy to set up, install,
and operate. Its reliability and economy have made it a necessity
in the audio chain of FM stations in all size markets with
all types of formats, worldwide.
