Array Size Compensation (ASC) Overlays
Three ASC overlays are available, and it is recommended that ALL enclosures in the array have ASC selected.
The 6 dB low-frequency shelving characteristic osets LF/MF array coupling.
Note: Single MV212 / MV212 XV do not normally require ASC overlay.
ASC OVERLAY DESCRIPTION OVERLAY
ASC 2 to 4: 2 to 4 elements
ASC 5 to 8: 5 to 8 elements
ASC +8: more than 8 elements
DISTANCE EQ COMPENSATION OVERLAY
All speakers are aected by air loss over distance, this set of
overlays is in increments of 3 m and ensures a balanced high
frequency response over distance. Peaking or Bell lters are
used to keep headroom in the high frequency band rather
than high shelf lters which unnecessarily use up headroom
for frequency which will not travel over far distances.
Rules of AirEQ:
DO NOT INSERT MORE THAN 1 FILTER AT THE SAME TIME.
FOR INTERMEDIATE DISTANCES, USE THE CLOSEST OVERLAY
AVAILABLE
AirEQ overlays are available at:
9 m, 12 m, 15 m, 18 m, 21 m, 24 m, 27 m, 50 m, and + 50 m
Here we have some examples of how the useful frequency
and gain changes over distance:
AirEQ 12 m
AirEQ 15 m
AirEQ 18 m
AirEQ 21 m
Two elements per amplifier DSP module block
AirEQ9 m – For elements within an array aimed at 9 m
distance
AirEQ24 m – For elements within an array aimed at 24 m

AirEQ50 m – For elements within an array aimed at 50m
