7.3.2.2 [12XTA_FR_100], [12XTA_FI_100], and [12XTA_MO_100] presets
The [12XTA_FR_100] preset features a high frequency shelving equalization (FOH applications). The preset also
includes a 100 Hz high-pass filter.
The [12XTA_FI_100] preset results in a nominally flat contour in free field conditions (speech reinforcement, classical
music, or fill distributed applications). The preset also includes a 100 Hz high-pass filter.
The [12XTA_MO_100] preset results in a nominally flat contour in half-space loading conditions (floor monitoring as well
as wall or ceiling-mounted applications). The preset also includes a 100 Hz high-pass filter.
Activate the LOAD PRESET menu from the LA4 amplified controller front panel and then select the desired preset.
Refer to the ‘‘LA4 - User Manual’’ for additional instructions. The preset is also accessible using the LA NETWORK
MANAGER software (refer to ‘‘LA NETWORK MANAGER - User Manual’’). Accessible controls in ‘‘HIGH-PASS’’
mode for ACTIVE 12XT are shown in the following chart:
