Rigging procedures
8.
Build another stack of two SB18 enclosures (hereafter called SB18#3 and SB18#4) by applying step 4 (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 SB18 user
documentation ). 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 7 (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).
