5.3 K1BUMP-FLIGHT c se
The L-ACOUSTICS® K1BUMP-FLIGHT c se has been exclusively designed to transport the K1-BUMP flying
structure.
The K1BUMP-FLIGHT is composed of the following elements (see also Figure 5):
•One wheeled bottom tr y.
•Two comp rtments.
•One remov ble tr y.
•One lid.
In its default configuration (see Figure 5), the K1BUMP-FLI HT allows transporting 2 K1-BUMP as well as additional
accessories in the removable tray such as delta plates, adjustable slings, accessories for rigging dV-DOSC® or KARA® as
downfill arrays, and others. The footprint is equivalent to the K1-CHARIOT’s one thus facilitating truck packing.
Note: Both K1-BUMP can be hooked and lifted from the case using motors without any physical handling. The inner
cut-outs of the compartments also allow transporting cables in place of the bottom K1-BUMP.
Its modular conception makes the K1BUMP-FLI HT ready to accept 2 additional compartments. This maximum
configuration allows transporting up to 4 K1-BUMP and the total height of the flight-case will be equivalent to the
height of an array of 4 K1 or K1-SB enclosures placed on a K1-CHARIOT.

6.1.2 LA-RAK rigging
It is possible to rig up to four LA-RAK touring racks to the K1-BUMP flying structure as it is described below. Before
applying this procedure, the K1-BUMP must have been prepared as described in [6.1.1].
All along the procedure:
•Strictly follow the sequence of the successive steps.
•Systematically ensure that each BLP is fully inserted by pulling on it.
1. Take a first LA-RAK and remove the dolly board:
. Turn a spring-loaded safety and slide out the coupling bar.
b. Repeat for the second coupling bar.
Figure 8: Removing the dolly bo rd from n LA-RAK
2. Place the LA-RAK on a K1-BUMP 2-rail template.
The LA-RAK must be installed with front panel oriented towards the K1-BUMP laser slits (or rear
panel towards the REAR identification plate as shown in Figure 9).

3. Secure the LA-RAK to the K1-BUMP :
. Turn a spring-loaded safety and slide in the coupling bar along the rails until the safety has returned to
locking position (a click is heard).
b. Repeat for the second coupling bar.
Figure 9: Rigging first LA-RAK to the K1-BUMP
4.If necess ry, install a second LA-RAK onto the second 2-rail template by repeating steps 1 to 3.
The LA-RAK touring racks must be arranged so as to properly balance the K1-BUMP’s centre of
gravity. Therefore, if only two racks are used each one must be placed directly onto the K1-BUMP
(see Figure 10).

1 When the final number of LA-RAK is 1 or 3, place the front motor chain and a rubber molding
on the extern l side of the r ck st bilizer (see Figure 14). This will prevent the K1-BUMP
from tilting when it is flown.
The K1-BUMP will recover stability after four K1 and/or K1-SB enclosures have been rigged. At
this moment the front motor chain and the rubber molding must be slid b ck into the groove
of the r ck st bilizer (see Figure 13).
