Mode (V Fade/X Fade)
While working in the Audio-F-Video mode, the audio sources will also change as the video
sources are switched. We can choose how the audio changes sources, whether it be a clean
cut (immediate switch) or some sort of transitioned change (cross fade or fade out & in). To
do this we would need to set up with the following menu options.

X Fade: PGM Audio / PVW Audio cross fade

V Fade: Fade out PGM Audio then fade in PVW Audio
Gain (-60 – 24 dB): adjustment of the PGM audio volume.
Delay (0 – 340 ms): sets the PGM audio delay.
Analog Out
You are also allowed to select a source of audio of your preference and output the selected
audio via Audio OUT. Open the GUI menu and select Audio
 Analog Out  Src where you
may select a source of audio from the following list.

PGM Audio

Follow

Input 1-8
If “Follow” is selected, the audio will enter Audio follow Video mode, i.e. playback of the
PGM audio via Audio OUT
without audio output delay . If “PGM Audio” is selected, the SE-
4000 will only play the PGM audio via Audio OUT with audio output delay . You may also
select to output one audio component of the 8 inputs via Audio OUT without audio output
delay .
Gain (-60 – 24 dB): adjustment of the audio volume at the AUDIO OUT.
Delay (0 – 340 ms): sets the delay of the audio at the AUDIO OUT.
