Audio input — individual audio groups (VGA, DVI, HDMI, composite video)

Number/signal type
HDMI inputs	3 stereo, unbalanced
All other inputs	2 stereo, unbalanced, per each (VGA, DVI, composite video) input group
Connectors
Composite video inputs	2 pairs of female RCA connectors
HDMI inputs	3 female 3.5 mm stereo mini jacks; tip (L), ring (R), sleeve (GND)
All other inputs	2 female 3.5 mm stereo mini jacks per input group; tip (L), ring (R), sleeve (GND)
