Thrust stages
Examples 6 and 7 show typical set-ups for large, thrust stage productions.
(6) WSX set-up for high power variety/orchestral production on
large thrust stage
front view
side view
Gives medium vertical & wide horizontal coverage up to 120Hz for audience on 3 sides - allowing for
ground effects.
1) Set the front & rear WSX arrays to match the main front & rear system farfield levels
around 120Hz
2) Set the front & rear W8Cs to balance the main systems + WSXs in the nearfield
3) Set the flown centre W8Cs to balance the main systems + WSXs + W8Cs in the L, R &
centre/mix position midfield areas
4) Set the apron W2s to fill the L, R & centre nearfield region
5) Set the apron WSXs to match the W2s around 120Hz
Again, left and right WSX arrays (but this time at front and rear) are augmented by
apron fills. The system set-ups may be thought of as three-sided versions of examples
3 and 5.
