[12XTP_FR_100], [12XTP_FI_100], and [12XTP_MO_100] presets
•
ALWAYS use the [12XTP_
] PASSIVE presets with the 12XTi enclosure.
•
NEVER mistake the [12XTP_
] PASSIVE presets for the [12XTA_
] ACTIVE presets.
The [12XTP_FR_100] ‘‘FRONT’’ preset features a HF shelving EQ and a 100 Hz high-pass filter for FOH applications
with subwoofers.
The [12XTP_FI_100] ‘‘FILL’’
preset results in a ‘‘flat’’ contour down to 100 Hz in free field conditions for use in speech
reinforcement, classical music, or close proximity fill applications.
The [12XTP_MO_100] ‘‘MONITOR’’ preset results in a ‘‘flat’’ contour down to 100 Hz in half-space loading conditions
for floor monitoring, wall, or ceiling-mounted applications.
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 presets are also selectable using the LA NETWORK
MANAGER software (refer to the
‘‘LA NETWORK MANAGER’’ user manual
). The accessible parameters in
‘‘HIGH-PASS’’ mode are shown in the following chart:

“HYBRID’’ mode
7.4.1
Description
In ‘‘HYBRID’’ mode the 12XTi and SB118 enclosures are connected to the same LA4 amplified controller thus limiting
the number of required units. The bandwidth of the system is extended down to 32 Hz. The recommended ratio is one
12XTi for one SB118.
7.4.2
Connecting the 12XTi and SB118 to the LA4
The 12XTi and SB118 enclosures connect to the LA4 outputs as follows: channels 1 and 3 are dedicated to one SB118
enclosure each, and channels 2 and 4 to 12XTi enclosures. Therefore, a single LA4 amplified controller can drive up to
two 12XTi and two SB118 enclosures (see Figure 6).
A maximum of
one SB118 enclosure
can be connected per
LA4 output channel 1 or 3
.
Note:
The system resources are optimized for two 12XTi and two SB118 per LA4.
