Walk around the auditorium, and make an overall
judgment of the surround level compared to the
screen level. Because of the “diffuse” nature of
the surround sound, it will commonly require a
slight increase in surround level to get it to match
the screen level. The tonal balance and acoustic
level should subjectively match.
Rotate the fader knob to set the surround level
trim desired. The range is –3 dB to +6 dB. This
example shows the level trim set to set to +1.2 dB.
