INSTALLATION
when you set up modulation with the 6300's test tone oscillator, correct
the peak modulation by turning down the AO 100% control and then
turning up D
limiter harder but will cause the loudness controller and loudness meter
to be calibrated correctly.
If the loudness in your market is different from that produced by an Op-
timod-TV using a factory preset, match this loudness to the on-air loud-
ness produced by the 6300 by editing the D
preset. This ensures that the loudness controller and loudness meter op-
erate correctly.

driving a Dolby Digital or analog television channel.

 Selecting a 32 kHz output sample rate will automatically set the highest
available audio bandwidth to 15 kHz.

will also affect the available range of test tone frequencies. When
