AUDIO CONTROL
16.1 AUDIO INPUTS
This section contains all the working parameters for the Falcon XT analog and digital inputs. In addition to these controls,
you can set parameters such as pre-emphasis and the main audio input (Input Setup).
16.1.1
Analog Input
The balanced analog audio sensitivity ranges from -10dBu to +10 dBu, with 0.1dBu-
steps. The section on Input Mode features the operating modes for the audio
processor inputting stage: the functional operating (or nominal operating) conditions
are either Stereo or Mono L + R, while the Mono L and Mono R functions are
considered to be the test or configuration mode.
In the input stage, a HPF (high pass filter) is available with two cutting modes: 5 Hz
or 30Hz. Generally speaking, for transmitters dating back to prior to the introduction
of DDS (therefore in all the transmitters still based on PLL digital frequency
synthesis), it is advisable to set the HPF at 30Hz, as in some cases subsonic
frequencies, or frequencies below this value, could influence the behaviour of the
transmitter exciter.
