6.1 SB18 transport
The optional
L-ACOUSTICS
®
SB18PLA dolly board (see Figure 1) can be secured to the SB18 enclosure by inserting
both captive pins in the front locator studs of the subwoofer (see Figure 3) thus allowing easy transportation and
protection of the enclosure.
It is recommended to use the L-ACOUSTICS
®
SB18COV protective cover (see Figure 1) in conjunction
with the SB18PLA .
6.2 SB18 flying or stacking
The SB18 fully integrated four-point rigging system allows the following setups (see also Figure 1 and Figure 3):
•
Flying a vertical array of up to 16 SB18 using the L-ACOUSTICS
®
M-BUMP structure. The M-BAR element
can also be added depending on the configuration.
•
Stacking a vertical array of up to 8 SB18 using the L-ACOUSTICS
®
M-BUMP, M-BAR, and M-JACK
elements.
•
Stacking a vertical array of up to 8 SB18 directly on the ground (for perfectly horizontal and regular surfaces
ONLY).
•
Mounting one XT or two KIVA enclosures using the built-in 35 mm/1.4 inch pole mount socket to easily create
a compact FOH system.
Refer to the SB18 Rigging manual [3.4] to get acquainted with the SB18 system specific rigging
procedures and mechanical limits.
6.3 SB18 connection
The SB18 subwoofer can be driven and powered by both dedicated
L-ACOUSTICS
®
LA4 and LA8 amplified
controllers. The LA4 can drive up to four SB18 enclosures (one per channel) and the LA8 can drive up to eight SB18
enclosures (2 per channel in parallel). For further details please refer to the
LA4 or LA8 User manual [3.4].
The SB18 is equipped with two 4-point SpeakON
®
connectors wired in parallel allowing connection with a second
SB18 in parallel using an L-ACOUSTICS
®
SP.7 link cable.
The SB18 connects to the LA4 using the
L-ACOUSTICS
®
SP10 or SP25 cables (see Figure 2 and Figure 4), and to the
LA8 using the DOSUB-LA8 cable in conjunction with the DO.7 , DO10 , or DO25 cable (see Figure 5).
A maximum of one SB18 enclosure can be connected per LA4 output channel.
A maximum of two SB18 enclosures can be connected per LA8 output channel.
ALWAYS connect the new DOSUB-LA8 cable adaptor to the LA8 (refer to the LA8 CACOM CABLES
Technical bulletin [3.4]). NEVER use the old DOSUB one.
