Analog Broadcasting Inputs
The transmitter does not have extensive audio processing capabilities. Use an external audio processor
to ensure that the audio source material is processed properly. An audio processor will adjust the

system. Carefully control the peak levels.
For monaural applications, the audio may be processed to provide up to 140% positive peak program
modulation, with a 5 kW RF carrier at the nominal ac voltage.
Refer to the Operating section of the
