"LOW-EXTENSION'' mode

7.4.1

Description

In ''LOW-EXTENSION'' mode the PASSIVE 12XTi and SB18i 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 PASSIVE 12XTi for one SB18i.
7.4.2

Connecting the 12XTi and SB18i to the LA4 / LA4X

The 12XTi and SB18i enclosures connect to the LA4 / LA4X outputs as follows: channels 1 and 3 are dedicated to one
SB18i enclosure each, and channels 2 and 4 to 12XTi enclosures. Therefore, a single LA4 / LA4X amplified controller
can drive up to two 12XTi and two SB18i enclosures (see Figure 6).
!
A maximum of one SB18i enclosure can be connected per LA4 / LA4X output channel.
CAUTION
Note: The system resources are optimized for two 12XTi and two SB18i per LA4 / LA4X.
