Rigging procedures
8.
Build another stack of two SB18 enclosures (hereafter called SB18#3 and SB18#4) by applying step
(p.70).
Orient all SB18 composing the array towards the audience to obtain an omnidirectional acoustic pattern
or turn one SB18 out of four from front to rear to obtain a cardioid acoustic pattern (refer to the
). As an example, the following gures show a cardioid SB18 array.
9.
Attach SB18#3 to SB18#2 as follows (see also the gure below):
a) Lower the array onto SB18#3 while aligning the four rigging points between SB18#2 and SB18#3.
b) Attach the four rigging arms of SB18#3 to SB18#2 as follows: disconnect a T-BLP from SB18#3, rotate the
rigging arm up, re-connect the T-BLP to the SB18#2 rigging point and the rigging arm ; repeat this procedure
until all 4 arms are secured.
10.
If the array is intended to be an SB18 standalone array, apply the following last procedure (see also the gure
above):
a) Repeat steps
(p.71) to 9 until all SB18 composing the array are rigged.
b) Raise the array to the desired height.
c) Secure the M-BUMP to the main rigging structure using two safety slings (not provided).
