Working With A Fixed Or Single Audio Source; Switching Between Different Embedded Audio Sources - Datavideo SE-2800 Instruction Manual

DIGITAL VIDEO SWITCHER

Working with a fixed or single audio source

Example 1:
We have two mono mics (channels 1 & 2) connected
to a HD camera. These embedded audio channels
are then output from this camera, HD-SDI, to the SE-
2800 switcher. If we want to only hear these two audio
channels regardless of the video channel used then we
would set up the switcher in the following way.
Press the ENTER key in the MENU area of the SE-
2800 keyboard to display the on screen menu on the
HDMI 1 output.
Change the Audio Association settings in the menu
system to show a value of 1 for each video input
channel. Press the ENTER key to store the audio
values chosen for each video input.

Switching between different embedded audio sources

Example 2:
We have two mono mics each connected to a different
HD camera. The embedded audio is then output from
each camera, HD-SDI, to the SE-2800 switcher. If we
want to hear the audio from each camera as the video
channels are switched, audio follows video, then we
would set up in the following way.
Press the ENTER key in the MENU area of the SE-
2800 keyboard to display the on screen menu on the
HDMI 1 output.
Change the Audio Association settings in the menu
system to show a value of 1 for each video input
channel that is associated with audio input 1. Then
change to a value of 2 each video input channel that is
associated with audio input 2. Press the ENTER key to
store the audio values chosen for each video input.
Change the SDI Embedded Audio setting in the
switcher's menu system to show a value of Group 1
and Pair 1. Press the ENTER key to store the audio
values chosen for each video input.

When switching between the video sources the audio
sources will also change. We can choose how the
audio will change 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 type = A/B cross fade
V type = Fade out A then fade in B
