VT X A12 | User Manual

11.6 - EXAMPLE USING LACP

This example is for a 12-cabinet VTX A12 array. The standard A12 preset is used with the Array Size Compensation

ﬁlter set to –3dB to oﬀset LF buildup and achieve a ﬂatter frequency response. As seen from the illustration below,

Array Size Compensation is globally applied to all array circuits. The bottom circuit includes some HF attenuation using

HF Throw Distance Compensation (Filter 3) to correct for proximity diﬀerences. Using some simple adjustments to the

LACP ﬁlters will get an A12 system to a very good staring point. Any further required adjustments will be dependent

upon the room and speciﬁc application.

TIP: The LACP parameters used in LAC to predict an array can be easily applied to an actual array in Perfor-

mance Manager. For information on how to import LACP parameters in Performance Manager, please refer

to the Performance Manager documentation.
