Be Brighter, Louder, Fuller-Legally-With
the CP-803 Composite Processor
- Market Dominance – Increase your station's
competitive loudness with no pumping or swishing.
- More Open
Sound – If you're already dominant, you
can reduce your audio compression and limiting and gain
a truly "open" sound while remaining
competitively loud.
- Fuller Sound – If your concern is fidelity, you
can virtually eliminate compression and limiting for a fuller, open sound
with no loss of loudness.
- Rejuvenate Existing Audio – If you're
thinking about upgrading or replacing a processor that's not quite
state-of-the-art, adding that CP-803 provides performance
equal to or better than new equipment-at less than 20% of
the cost.
- Add On Later – If you decide to add a new
processor later on, go ahead. The CP-803 Composite Processor
will audibly improve its performance.
Eliminates Overshoot
and Controls Peaks
The CP-803 Composite Processor improves the sound of your
FM station by eliminating peaks of over-modulation in
two important ways:
First, the CP-803 eliminates the brief electrical overshoots
that exist in all audio limiters and stereo generators-
even those described as "overshoot-compensated".
Preventing such overshoots increases modulation with essentially
no audible effect on the signal.
Second, the Processor controls the high-frequency peaks that are
present in all program material. Though not Acoustically significant,
these peaks cause over-modulation. Controlling them makes greater
average modulation possible. The audible effect is minimal, far
less than that of conventional variable-gain devices.
The CP-803 offers the best combination of quality and loudness
available. It gives you the first few dB of loudness with no audible
increase in distortion. How many additional "penalty-free" dB you
can achieve after that depends on how much you process the audio
before it reaches the Composite Processor. The less prior processing,
the more the CP-803 can do for your station's sound.
Unique Patented Design
The Modulation Sciences CP-803 is significantly different from
conventional processors. First, the CP-803 corrects the distortion
that conventional processors sometimes create. But, more importantly,
there is a basic difference in the way it operates. In fact, the
unique design of the CP-803 Composite Processor has earned it a
U.S. patent.
While conventional audio processors work with the left and right
audio, the CP-803 deals with the composite signal that comes out
of the stereo generator. This baseband signal is composed of the
L + R main channel, the 19 kHz pilot and the L-R subcarrier. By
working on this composite signal instead of the left and right
audio, many conventional audio problems are avoided.
Not A Baseband Clipper
Don't confuse the CP-803 Composite Processor with illegal baseband
clippers! The CP-803 is completely legal – primarily because
it operates differently than distortion generating baseband clippers.
These illegal clippers clip the 19 kHz pilot as well as the signal
and create a particularly ugly type of clipping distortion. The
CP-803 does not clip the pilot, so it will never produce the kind
of spectral garbage that baseband clippers do.
If your stereo generator has a baseband clipper built in, you can
benefit from adding the CP-803 to your audio chain. Because you're
not allowed to modulate the 19 kHz pilot under U.S. FCC regulations,
baseband clippers restrict you to 0.5 dB of clipping. They cannot
meet FCC standards without readjustment. The CP-803, on the other
hand, does meet FCC standards. It does not clip the pilot, so it
can clip the signal as much as 8 dB without readjustment.
In fact, thousands of stations have improved their sound by replacing
older clipper designs with the CP-803. Because conventional clippers
damage the 19 kHz pilot, they produce an ugly kind of distortion
and a dynamic loss of stereo separation. The CP-803 doesn't do
any of this, so you can retain clarity and maintain stereo separation.
Enhances Existing Processing
Decibel for decibel, the CP-803 produces less distortion than any
other kind of processor. That's because it has no variable gain
element to pump, swish or breathe. In fact, the CP-803 is unique
among processors: below 100% modulation, it's impossible to detect
whether or not it's in the audio chain.
As a result, many of out customers use it along with their other
processing to upgrade the quality of their signal. By reducing
the amount of conventional processing -and using the CP-803 to
do the rest- these stations have noticeably increased dynamic range
and brought the sparkle back to their sound.
The CP-803 does not eliminate conventional processing; it enhances
it. Some stations use it to reduce the amount of audio processing,
which results in a more "open" sound
with greater dynamic range. Other stations use the CP-803 to gain loudness with
little or no increase in distortion. In either case, the CP-803 delivers more
dynamic range, less distortion and more presence – all while
maintaining competitive loudness.
Easy To Install, Set Up and Operate
The CP-803's compact single rack-unit size makes it easy to install
even when you're pressed for space. Because it's highly RF-resistant,
you can place it just about anywhere. The CP-803 is happy in ambient
temperatures between 0 and 50 degrees C (32 and 122 degrees F).
The CP-803 should be placed between the output of your stereo generator
and the wideband input of your exciter. For stations using a composite
STL, it should be connected between the output of the STL receiver
and the wideband input of the exciter. The CP-803 uses BNC connectors
for its input and output to assure compatibility with most broadcast
equipment.
Typical set-up time for the CP-803 is 10 to 15 minutes. All you
need is normal program material and a standard modulation monitor.
Since the phase shift of the CP-803 is negligible, it won't affect
stereo separation, so there is no need to adjust your stereo generator.
Except for the annual Pilot Trim check, the complete operation
of the CP-803 can be verified without the need for special test
equipment. All that's needed is regular program material and a
modulation monitor.
The CP-803 is designed for long-term stability. MSI uses tight-tolerance
resistors and capacitors in critical circuits of the design. Some
of these components have long-term drift specifications rated in
tens of parts per million! To further assure stability, these components
are encapsulated. As a result, the drift of the CP-803 is less
than that of a typical stereo generator. Only the Pilot Trim adjustments
need to be checked – and
those, only once a year.
Maximum Performance At Low Cost
Nothing else matches the combination of low price, high performance
and reliability you get with the MSI CP-803 Composite Processor.
When you add up the benefits of up to 6 dB of additional loudness
and a cleaner, brighter, more distinctive sound at a price that's
a fraction of what other processors cost, you'll see why thousands
of CP-803s have been purchased by FM stations in all size markets
with all types of formats, worldwide.
The CP-803 is the most cost – effective investment you can
make in your station's sound. Isn't it time you took advantage
of its benefits? |
