GEO TANGENT ARRAY RIGGING SYSTEM P.23
After having positioned the top enclosure, insert the pins
into the front and rear attachment points and lock them
with R clips (see picture). The bumper’s rear mounting
point should be connect to the hole marked “LIFT” on the
GEO Angle Adjustment Plate. NOTE: The top GEO
enclosure is always parallel to the bumper.
Assembling a vertical GEO tangent array
Place the top GEO cabinet (attached to the bumper) face
down on a horizontal surface (a narrow length of carpet
will help protect the grills). Align the top holes of the next
GEO cabinet’s front attachment bar with the bottom
holes of the first GEO cabinet’s front attachment bar and
insert the pins to connect both sides at the front (see
below). Repeat this operation until the entire array is
connected at the fronts of the enclosures.
Setting the angles between adjacent
GEO enclosures
To set the angles between enclosures to the
values specified for this array by NS-1, begin by
lifting the array until only the bottom enclosure
remains on the ground. This will make it easier to
align the angle-setting bars with the proper holes
in the angle-setting plates (see Figure 5).
Align the angle-setting bars with the proper holes
in the angle-setting plates. For all GEO
enclosures except the S830, insert pins through
the hole in the angle-setting plate and the oblong
slot at the end of the angle-setting bar (see Figure
6).
NOTE: GEO S830’s are always “tight-packed” with the adjacent enclosure so that the wavefronts will be
tangent and will combine coherently without interference. The angle of a GEO S830 at the bottom of a curved
vertical array and just below a GEO S850 will therefore be 17.5°. The angle between any two GEO S830’s will
always be 30°.
Continue lifting the array so that the fronts of all the enclosures are accessible, then lock all the attachment
pins in place with R-clips. While the array is being raised to the operating height specified by NS-1, the
enclosures will fall into the proper angular alignment with each other.

CAUTION: The GEO Bumper is designed to safely fly a maximum of 24 GEO loudspeakers. Before
raising the array to its operating height, be sure to check that all attachment pins are in place, secured
by R-clips or another locking mechanism and that both sides angles settings are strictly identical.
