Rigging procedures
b) Lift up one side of the M-BUMP, place the M-BAR beneath it with M-JACK on the ground, and lower the M-BUMP
so as to insert both M-BAR studs into the M-BUMP slits.
c) Secure by inserting both preceding T-BLP.
4.
Adjust the stacking platform in horizontal position by setting the heights of the 4 M-JACK as follows:
a) Unscrew the locking nut on each M-JACK (16 mm hex key).
b) Place an inclinometer device onto the platform in the direction parallel to the M-BAR and rotate the 4 M-JACK
knobs to adjust the platform in the horizontal position.
The inclinometer can be mounted to the integrated laser plate (see
(p.187)).
In case of high resistance the user can also screw the base nut (14 mm hex key) in place of a knob.
c) Put an inclinometer device in the direction perpendicular to the M-BAR and verify that the platform is also
horizontal in this direction.
The handheld inclinometer included in the
TECH TOOLCASE
can be used in this step.
d) Lock each M-JACK height by rmly screwing in the locking nut (16 mm hex key).
5.
Link a rst SB18 (hereafter called SB18#1) to the M-BUMP as follows:
a) Place SB18#1 at the rigging location and remove the dolly board.
b) Turn the SB18#1 logo upwards. Orient the front grill towards the audience or backwards.
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.
c) Place SB18#1 on the M-BUMP by aligning the four rigging points.
d) Link the four rigging arms of SB18#1 to the M-BUMP as follows: disconnect a T-BLP from SB18#1, rotate the
rigging arm down, re-connect the T-BLP to the M-BUMP rigging point and the rigging arm ; repeat this procedure
until all 4 arms are secured.
