OPERATION

7.1

System configuration

The choice of a system configuration should be the result of an electro-acoustic study conducted by an expert (System
Engineer or Audio Consultant). However, this will not be discussed here as sound-design aspects are beyond the scope
of this manual. This study can rely on the simulations modeled in SOUNDVISION software, yielding electro-acoustic
predictions which take into account the enclosures' manufacturer data and particular situational usage, as well as the
projected environment.
Several operation modes are for building all the common configurations (L/R, L/C/R, distributed), and each mode is
associated with a set of factory presets. Other non-conforming configurations do not correspond to any preset.
The 8XT enclosures can be used as a standalone system in the "FULL RANGE'' mode or in combination with
subwoofers in the "HIGH-PASS'' and "HYBRID'' modes.
For each mode a distinction is drawn between ''FRONT'', ''FILL'', and ''MONITOR'' presets as they respectively
match front-of-house, distributed, and half-space loading applications.
!
The LA4 output channel assignment varies with the preset selected by the user.
Always check that each 8XT enclosure is connected to the correct output channel before operating.
CAUTION
Note: The latest version of the preset library can be supplied by an L-ACOUSTICS
also downloadable on the L-ACOUSTICS
7.2

"FULL RANGE" mode

In ''FULL RANGE'' mode the 8XT enclosures are used in standalone configurations within their nominal bandwidth, for
applications not requiring low frequency extension.
7.2.1

Connecting 8XT to LA4

Each 8XT enclosure must be connected to an LA4 output channel ranging from channel 1 through 4. An additional 8XT
enclosure can be connected in parallel with each of the first ones. Therefore a single LA4 amplified controller can drive
up to eight 8XT enclosures (see Figure 5).
Note: The system resources are optimized for four or eight 8XT per LA4.
