OPTIMOD 6300 DIGITAL
 AGC (stereo enhancement, equalization, and AGC without peak limiting)
 AGC+LIM (stereo enhancement, equalization, AGC, and look-ahead peak
limiting)
 MULTIBAND (stereo enhancement, equalization, AGC, and 2-Band or 5-
Band compression without peak limiting)
 MB+LIM (stereo enhancement, equalization, AGC, 2-Band or 5-Band com-
pression, and look-ahead peak limiting)
If you set E
case, choosing:
AGC causes the input signal to be passed to the analog output with no
dynamics processing (just stereo enhancement and equalization).
AGC+LIM results in stereo enhancement, equalization, and look-ahead
limiting.
MULTIBAND results in stereo enhancement, equalization, and 2-Band or
5-Band compression without AGC.
MB+LIM results in stereo enhancement, equalization, and 2-Band or 5-
Band compression with look-ahead limiting but without AGC.
CAUTION: If the outputs are configured for no peak limiting, they are
usually unsuited for driving a transmitter. An exception is an STL having
16 bits of dynamic range or more. In this case, it is often practical to drive
it with the AGC alone, allowing additional headroom for the overshoots
that the 6300's peak limiter would have otherwise removed.
If you use the low-delay output to drive your studio monitor speakers as
well as talent headphones (which may be necessary if your facility has
only one monitor input for both), then we recommend connecting a loss-
of-carrier alarm to one of the 6300's GPI inputs. Program this input to
mute the monitor output in the event that carrier is lost. This simulates
normal "off air" monitor functionality and immediately alerts the staff if
the transmitter goes off the air unexpectedly.
You can program any GPI input for Monitor Mute functionality. See
Remote Control Interface Programming on page 2-45 for instructions on
how to program a GPI input.
11. Set the digital output #1 source.
A) Press the N
EXT
B) [Skip this step if you will not be using digital output #1.]
Turn the knob to choose one of the following:
 AGC (stereo enhancement, equalization, and AGC without peak limiting)
 AGC+LIM (stereo enhancement, equalization, AGC, and look-ahead peak
limiting)
 MULTIBAND (stereo enhancement, equalization, AGC, and 2-Band or 5-
Band compression without peak limiting)
