casts, and any other channel that uses a lossy codec. When in doubt, use
F preemphasis.

When operated pre-emphasized, the 6300's MB look-ahead limiter
should only for light protection limiting. If you use too much gain reduc-
tion in the look-ahead limiter, you will hear pumping on material with a
lot of high frequency energy. The 6300 cannot process for high loudness
on pre-emphasized radio channels. Use an Orban Optimod-FM for such
applications.

the analog output source to:
 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)
See step 10 on page 2-14.

applications.
If you are sending the analog output of the 6300 through a digital link
that uses a lossy codec like MPEG, APT-X, or Dolby, set the output F
Lossy codecs cannot handle pre-emphasized signals.
If you intend to use the analog output for headphones, set the output
F .

If you choose P
emit either the AGC+LIM signal or the MB+LIM signal monitoring [see
step (A) above].
If you emit the AGC+LIM signal, peak levels will only be controlled if you
set the AGC preemphasis to 50S or 75S in step 7 on page 2-23. This is
the only way to make the look-ahead limiter aware of the preemphasis.
If you emit the MB+LIM signal, peak levels will only be controlled if you
set the multiband preemphasis to 50S or 75S in step 8 on page 2-23.
If you are driving a pre-emphasized channel and can bypass the channel's
internal preemphasis filter, use P
channel's preemphasis filter or if you will use the analog output for
monitoring, set the output F
