Audio inputs 1-3 and 5-8 — These 5-pole captive screw connectors support analog,
balanced or unbalanced, stereo audio as three line level inputs (1-3) and four line level
analog stereo inputs (5-8).
Audio from the HDMI inputs 5-8 can be de-embeded from the HDMI source. This
allows the user to choose to select audio either from the HDMI inputs or the analog
audio from these four captive screw inputs. Once an audio source is selected, the
unselected source is disabled. The default selection is audio from the HDMI inputs.
Connect audio sources to these 5-pole, captive screw connectors. Wire the connector
for line level analog stereo as shown below.
