"FULL RANGE" mode

7.2.1

Description

In ''FULL RANGE'' mode the 8XT enclosures are used in standalone configurations within their nominal bandwidth
(65 Hz – 20 kHz), for applications not requiring low frequency extension.
7.2.2

Connecting the 8XT to the LA4 / LA4X

Each 8XT enclosure must be connected to an LA4 / LA4X 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 / LA4X
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 / LA4X.
Note: This drawing is only a cabling scheme and does not represent a valid configuration.

[8XT_FR], [8XT_FI], and [8XT_MO] presets

The [8XT_FR] ''FRONT'' preset features LF and HF shelving EQ for standalone FOH applications without subwoofers.
The [8XT_FI] ''FILL'' preset results in a ''flat'' contour in free field conditions for use in speech reinforcement, classical
music, or close proximity fill applications.
The [8XT_MO] ''MONITOR'' preset results in a ''flat'' contour in half-space loading conditions for floor monitoring, wall,
or ceiling-mounted applications.
Activate the LOAD PRESET menu from the LA4 / LA4X amplified controller front panel and then select the desired
preset. Refer to the LA4 / LA4X user manual for additional instructions. The preset is also accessible using the LA
NETWORK MANAGER software (refer to the ''LA NETWORK MANAGER'' user manual). The accessible
parameters in ''FULL RANGE'' mode are shown in the following chart:
