"LOW-EXTENSION'' mode

7.4.1

Description

In ''LOW-EXTENSION' mode the 8XT and SB18 enclosures are connected to the same LA4 / LA4X amplified
controller thus limiting the number of required units.
The bandwidth of the system is extended down to 32 Hz.
The recommended ratio is two 8XT for one SB18.
7.4.2

Connecting the 8XT and SB18 to the LA4 / LA4X

The 8XT and SB18 enclosures connect to the LA4 / LA4X outputs as follows: maximum two 8XT in parallel or 1 SB18
per output channel. Therefore, a single LA4 / LA4X amplified controller can drive up to four 8XT and two SB18
enclosures (see Figure 7).
!
This mode requires a custom preset.
Refer to the LA4 or LA4X user manual and to the LA NETWORK MANAGER tutorial for
additional instructions.
IMPORTANT
Note: The system resources are optimized for two or four 8XT and two SB18 per LA4 / LA4X.
