Audio Function
5.1 Overview
The HS-2850 has a simple, cost effective,
audio switcher
built in. This allows the HS-2850 to
take audio from several sources either XLR analogue, SDI and/or HDMI inputs. This audio
can be embedded onto the HDMI and SDI outputs and/or fed to the analogue XLR audio
output connections.
You may de-embed audio from selected SDI or HDMI inputs and then connect this audio
from the XLR outputs of the switcher to a separate external Audio Mixer, such as the
Datavideo AM-100. Other audio sources such as microphones and background music can
then be added at the AM-100.
Once the audio has been mixed externally in the AM-100 with any microphones or music
sources it can then be fed back into the HS-2850 on the analogue XLR inputs. The HS-2850
can then embed this externally mixed audio on to the Program SDI and HDMI outputs.
