"HIGH-PASS" mode

In the ''HIGH-PASS'' mode the ACTIVE 12XT enclosures are 100 Hz high-pass filtered to allow for coupling with the
dedicated complimentary SB118 subwoofers. The bandwidth of the system is extended down to 32 Hz. The
recommended ratio is one ACTIVE 12XT for one SB118.
7.3.2.1
The first two ACTIVE 12XT enclosures are connected to output channels 1 and 3 of the LA4 controller. An additional
ACTIVE 12XT enclosure can be connected in parallel with each of the first ones. Therefore a single LA4 amplified
controller can drive up to four ACTIVE 12XT enclosures (Figure 10).
Note: The system resources are optimized for two or four ACTIVE 12XT per LA4.
