Horizontal “Spacing” of Screen Channel Systems
For a 3-channel (L,C,R) system, L + R speaker channels should be placed
equidistant from center of screen image area, so that they are just inside the
screen area when screen is masked for the widest format (typically 2.35:1).
Acoustically
transparent side
masking should be
used to prevent
blocking of HF
when side masking
for a “flat” picture
is moved in
format.
