resulting audio will return and be connected to the audio inputs for the purpose of (re)-embedding
the audio to the SDI output. The selection of the audio groups determines the SDI channel that the

AUDIO FOLLOW VIDEO function is primarily used in talk show or live news broadcasting. Voices of
different guests are directly collected by the corresponding cameras, thus, when the program
director switches between different guests, the video is switched at the same time with voice of
the guest during program broadcasting. This function is definitely an indispensable function during
live broadcasting.
AUDIO FIXED
The AUDIO FIXED method, allows a user to manually select which audio input can be matched to the
SDI video input and assigned to the audio output terminals, which is shown in the example below:
The table below illustrates that the sound of video input 1 is used for all individual video inputs.
AUDIO CROSSPOINTS
INPUT 1 (BUTTON 1) 1
INPUT 2 (BUTTON 2) 1
INPUT 3 (BUTTON 3) 1
INPUT 4 (BUTTON 4) 1
INPUT 5 (BUTTON 5) 1
INPUT 6 (BUTTON 6) 1
The
AUDIO FIXED
function is primarily used during big (concert) events and (wedding) parties. One
camera picks up the audio of the audience and/or ambience of that video input 1, which is assigned
to be sent to the audio output. The other cameras are assigned to this same audio of video input 1.
When the operator switches between the video sources, the sound of video input 1 remains on all
the time.
