Digital Multipurpose Audio Processor
Informacja
Orban’s all-digital OPTIMOD 6300 Audio Processor can help
you achieve the highest possible quality digital audio
broadcast, digital television, and netcast audio processing.
Thanks to versatile signal routing, the 6300 can also serve
as a studio AGC with an all-digital signal path, and
simultaneously as a talent headphone processor.
Because all processing is performed by high-speed
mathematical calculations within Motorola DSP56367 Digital
Signal Processing chips, the processing has cleanliness,
quality, and stability over time and temperature that is
unmatched by analog processors.
OPTIMOD 6300 is descended from the industry-standard OPTIMOD
audio processors for radio and television. Thousands of
these broadcast-specific processors are attracting and
holding audiences all over the world. They have proven that
the “OPTIMOD sound” can attract and keep an audience even in
the most competitive commercial environment.
Because OPTIMOD 6300 incorporates several audio processing
innovations exclusive to Orban products, you should not
assume that it can be operated in the same way as less
sophisticated processors. If you do, you may get
disappointing results.
User-Friendly Interface
An LCD and full-time LED meters make setup, adjustment and
programming of OPTIMOD 6300 easy—you can always see the
metering while you are adjusting the processor. Navigation
is by dedicated buttons, soft buttons (whose function is
context-sensitive), and a large rotary knob. The LEDs show
all metering functions of the processing structure (2-band
or 5-band) in use.
Push one of the dedicated buttons to “Recall” a preset, to
“Modify” processing, or to access the system’s Setup controls.
Absolute Control of Peak Modulation
The 6300 precisely controls peak levels to prevent
overmodulation. The maximum level of the digital samples is
controlled to better than 2%.
While primarily oriented toward “flat” media, the 6300 can
also provide preemphasis limiting for the two standard
preemphasis curves of 50μs and 75μs. This allows it to
protect pre-emphasized microwave links, satellite uplinks
and similar channels where protection limiting or light
processing is required. It can also be used to process
analog television FM aural carriers in television ap-
plications because these are usually processed lightly
compared to FM radio.
Because its processing is configured to be most effective
with “flat media,” the 6300 cannot provide extreme loudness
for pre-emphasized radio channels. Use one of Orban’s
Optimod-FM processors for this application.
