Laws and regulations: The suspension of large, heavy objects in public places is subject to numerous
laws and regulations at the national, federal, state, provincial, and local levels. This manual does not
address the specifics of any such applicable laws and government regulations. This manual details
procedures and practices consistent with those generally acknowledged as allowable and safe in
Europe. However, the user must assume responsibility for making sure that use of any K-array system
and its components in any particular circumstance or venue conforms to all applicable laws and
regulations in force at the time.
Personnel health and safety: During installation and setup, personnel should wear protective headgear
and footwear at all times. Under no circumstances should personnel climb on the loudspeaker
assembly.
Wind loads: In case of outdoor installation, assure that wind does not interfere with the system’s
stability, taking extra securities like chains, weights, ropes or any other certified anchoring systems.
Ground stacking: Do not ground stack a cluster on uneven ground or platform. If the system is ground
stacked on a structure, platform or stage always check that it can support the total weight of the
system. Always check the stability of the system. When stacking more than two KH5 or more than
three KH3 or more than four KH2, always secure the base to a stable surface with chains, ropes or
any other certified anchoring systems.

The K-HCBASE accessory allows the stacking of up to three KH5 units and up to four KH3 units while
the K-HCBASE2 allows the stacking of up to six KH2 units.
5.1 STACkING A kh5/kh3 CLUSTER
The following step-by-step instructions explain how to stack a cluster composed of three KH5
elements. Follow the same procedure to stack a cluster composed of KH3 units.
1. Position the base on a flat surface and position the first KH5/KH3 unit as shown in the picture
below.
• Do not ground stack a cluster on uneven ground or platform.
If the system is ground stacked on a structure, platform or
stage always check that it can support the total weight of
the system.
• Do not gound stack more than three KH5 or four KH3 units.
• Always check the stability of the system. When stacking
three KH5 or four KH3, always secure the base to a stable

5.2 STACkING A kh2 CLUSTER
These step-by-step instructions explain how to stack a cluster composed KH2 units. Please note that
you will need the K-HCBASE2 accessory to stack the cluster. The K-HCBASE2 is very similar to the
K-HCBASE but features holes with a different diameter to insert smaller pins.
1. Position the base on a flat surface and position the first KH2 unit as shown in the picture below.
• Do not ground stack a cluster on uneven ground or platform.
If the system is ground stacked on a structure, platform or
stage always check that it can support the total weight of
the system.
• Do not gound stack more than 6 KH2.
• Always check the stability of the system. When stacking
more than four KH2, always secure the base to a stable
surface with chains, ropes or any other certified anchoring
systems.
