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)

applications. However, if you are using a TVAxxx preset (see Table 3-3 on
page 3-31) and driving an analog TV transmitter (i.e., one transmitting an
FM analog aural carrier using 50s or 75s preemphasis), it is best to de-
feat the transmitter's built-in preemphasis and to allow the 6300 to pro-
duce the preemphasis instead. By minimizing the number of preemphasis
and deemphasis stages in the transmission path, this minimizes peak
overshoot and controls peak modulation more tightly.
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 8 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 9 on page 2-23.
