Connecting the PASSIVE 12XT to the LA4 / LA4X

Each PASSIVE 12XT 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 PASSIVE 12XT enclosures (see Figure 6).
Note: The system resources are optimized for four PASSIVE 12XT per LA4 / LA4X.

[12XTP_FR], [12XTP_FI], and [12XTP_MO] presets

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
