Once the audio is mixed externally with any microphones or audio sources it can then be fed back into the
HS-2200 on the analogue XLR inputs. The HS-2200 can then embed this externally mixed audio on to the
Program SDI outputs.
AUDIO FOLLOW VIDEO
AUDIO FOLLOW VIDEO function is also known as audio follow video. This means that the audio source will
switch with the corresponding video input, and actually follow the T-bar function. The active audio is de-
embedded and sent to the audio output terminals for processing and/or audio levelling/ and or adding
more audio sources. The 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 will be embedded to exactly.
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.
