"HYBRID'' mode

In the ''HYBRID'' mode the 8XT 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 two 8XT for one SB118.
7.4.1

Connecting 8XT and SB118 to LA4

The 8XT and SB118 enclosures connect to the LA4 outputs as follows: channels 1 and 3 are dedicated to both SB118
enclosures, channels 2 and 4 are dedicated to 8XT enclosures. Each 8XT enclosure can be paired in parallel with an
additional 8XT. Therefore, a single LA4 amplified controller can drive up to four 8XT and two SB118 enclosures (see
Figure 7).
!
A maximum of one SB118 enclosure can be connected per LA4 output channel 1 or 3.
CAUTION
Note: The system resources are optimized for two or four 8XT and two SB118 per LA4.
