The 108P or 112P can be used with a loudspeaker stand (L-ACOUSTICS recommends the K&M
21435 or equivalent). The footprint (base diameter) must be at least 1300 mm and withstand a
maximum centric load of 350 N (35 kg) or higher. Tripod stand legs must be completely opened and
the height must not exceed 2020 mm when used with the 108P and 1420 mm when used with the
112P.
Always ensure that the ETR112XT or ETR15P rotating arm is securely fastened by verifying that the
spring-loaded locking pin at the pivot point is correctly seated before adjusting the tilt angle of the
112P or SB15P.
When using ETR8-2, ETR112XT or ETR15P in the vertical orientation, always install the U-bracket
with the fixed arm on the bottom and the pivoting arm on top.
Maximum one 112P can be rigged per XTLIFTBAR.
L-ACOUSTICS recommends the use of safety steels at all times.
Attachment to concrete has not been investigated during the CSA approval.
