setting reference in section 6.2).

7.3.1

"FULL RANGE" mode

In ''FULL RANGE'' mode the ACTIVE 12XT enclosures are used in standalone configurations within their nominal
bandwidth, for applications not requiring low frequency extension.
7.3.1.1
The first two ACTIVE 12XT enclosures are connected to output channels 1 and 3 of the LA4 controller. An additional
ACTIVE 12XT enclosure can be connected in parallel with each of the first ones. Therefore a single LA4 amplified
controller can drive up to four ACTIVE 12XT enclosures (Figure 9).
Note: The system resources are optimized for two or four ACTIVE 12XT per LA4.

7.3.1.2
The [12XTA_FR] preset features a low and high frequency shelving equalization (FOH applications).
The [12XTA_FI] preset results in a nominally flat contour in free field conditions (speech reinforcement, classical music, or
fill distributed applications).
The [12XTA_MO] preset results in a nominally flat contour in half-space loading conditions (floor monitoring as well as
wall or ceiling-mounted applications).
