AUDIO CONTROL

16.2 AUDIO OUTPUTS

This section contains all the working parameters for the Falcon XT analog output and digital output.

16.2.1

Analog Output

OUTPUT LEVEL:

the analogue output level of the Falcon XT. The values

settable range from -6.0 dBu to +20.0 dBu in 0.1dBu-steps

ANALOG DE-EMPHASIS:

the ability to filter the analog output to remove

the emphasis effect. It is also possible to adjust the group delay within the
range of 0 to +3 mS (Group Delay Adjust) if the transmitter experiences
emphasis decoding problems.

ANALOG OUTPUT IMPEDANCE:

this option lets you select the output

impedance for the Falcon XT. The values allowed

are 600Ω or 10kΩ.

ANALOG OUTPUT SOURCE SELECTION:

with this Falcon XT function you can decide which signal to place at the

Falcon XT analog output. Audio signals can be routed with the following options: Input (actually a bypass) - Signal
processed - Generator. The generator allows you to set the audio generated by the internal signal generator at the
output. To set the parameters, see "Signal Processor".

16.2.2

Digital Output

OUTPUT LEVEL:

the analogue output level of the Falcon XT. The values

can be set from -25.0 dBFs to + 0 dBFs.

DIGITAL DE-EMPHASIS:

the ability to filter the digital audio output to

remove the emphasis effect. It is also possible to adjust the group delay
within the range of 0 to +3 mS (Group Delay Adjust) if the transmitter
experiences emphasis decoding problems.

DIGITAL OUTPUT RATE:

the sampling frequency of the digital output

signal. The values can be set at: 32 kHz, 44.1 kHz, 48kHz, 64kHz, 88.2
kHz, 96 kHz and

INP.SYNC

, which sets the frequency value depending

on the sampling frequency of the input signal. Everything is done
automatically.

DIGITAL OUTPUT RESOLUTION:

this control sets the resolution of the digital output signal.

DIGITAL OUTPUT SOURCE SELECTION:

with this Falcon XT function you can decide which signal to place at the

Falcon XT analog output. Audio signals can be routed with the following options: Input (actually a bypass) - Signal
processed - Generator. The generator allows you to set the audio generated by the internal signal generator at the
output. To set the parameters, see "Signal Processor".
