BS.1770 Safety Limiter: The 6300 includes a BS.1770 safety limiter function that
will prevent a BS.1770-2 loudness meter with a 10-second integration time from
indicating higher loudness than the setting of the BS.1770 T
This limiter is active in all "TV" factory presets. See BS.1770 Safety Limiter on
page 3-13 for a discussion of why we included this limiter and why we don't
think you should use it.

The OPTIMOD 6300 Digital Audio Processor

Orban's all-digital Optimod 6300 Audio Processor can help you achieve the highest
possible quality digital audio broadcast, digital television, and netcast audio process-
ing. 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
digital signal processing (DSP) chips, the processing has cleanliness, quality, and sta-
bility over time and temperature that is unmatched by analog processors.
The 6300 is Dialnorm-aware. Loudness control is excellent when measured by the
ITU BS.1770-2 standard (as specified in ATSC A/85:2011) or by the 6300's built-in CBS
Loudness Meters. When properly installed and set up, the 6300 will automatically
make a station compliant with the CALM Act.
OPTIMOD 6300 is descended from the industry-standard OPTIMOD audio processors
for radio and television. Thousands of these broadcast-specific processors are at-
tracting 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.
