VERSION 1.1
7.2
"FULL RANGE" mode
7.2.1
Description
In ''FULL RANGE'' mode the 12XTi enclosures are used in standalone configurations within their nominal bandwidth
(55 Hz – 20 kHz) for applications not requiring low frequency extension.
7.2.2
Connecting the 12XTi to the LA4 / LA4X
Each 12XTi enclosure must be connected to an LA4 / LA4X output channel ranging from channel 1 through 4.
Therefore, a single LA4 / LA4X amplified controller can drive up to four 12XTi enclosures (see Figure 4).
Note: The system resources are optimized for four 12XTi per LA4 / LA4X.

[12XTP_FR], [12XTP_FI], and [12XTP_MO] presets
!
•
ALWAYS use the [12XTP_
•
NEVER mistake the [12XTP_
CAUTION
The [12XTP_FR] ''FRONT'' preset features LF and HF shelving EQ for standalone FOH applications without
subwoofers.
The [12XTP_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 [12XTP_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 presets are also selectable 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:
