Placement; Rigging - Mackie DRM18S Owner's Manual

Placement

WARNING: Installation should only
be done by an experienced technician.
Improper installation may result in damage
to the equipment, injury or death. Make sure that
the DRM18S is installed in a stable and secure
way in order to avoid any conditions that may be
dangerous for persons or structures.
DRM18S subwoofers are designed to sit on the floor
or stage as the main PA. A socket is provided on top
of the DRM18S for mounting DRM loudspeakers. The
SPM400 is a great pole-mount option. See the hookup
diagrams starting on page 5.
The DRM18S subwoofer may also be flown via its
integrated fly points as detailed on the following
pages. Be sure to read the PA-A2 Eyebolt Installation
Instructions, as well.
NEVER attempt to suspend a DRM18S
subwoofer by its handles.
Check to make sure that the support surface
(e.g. floor, etc.) has the necessary mechanical
characteristics to support the weight of the
subwoofer(s).
When pole-mounting loudspeakers, be sure that they
are stabilized and secured from falling over or being
accidentally pushed over. For stacked scenarios, it is
highly suggested that straps are utilized. Failure to
follow these precautions may result in damage to the
equipment, personal injury, or death.
As with any powered components, protect them from
moisture. Avoid installing a DRM18S in places exposed
to harsh weather conditions. If you are setting them up
outdoors, make sure they are under cover if you expect
rain.

WARNING: Installation should only be done
by an experienced technician. Improper
installation may result in damage to the
equipment, injury or death. Make sure that the
DRM18S is installed in a stable and secure way
in order to avoid any conditions that may be dangerous
for persons or structures.
WARNING: The cabinet is suitable for rigging
via its fly points. NEVER attempt to suspend
a DRM18S by its handles.
The fly points of the DRM18S are shown below
while examples of a flown DRM18S are displayed
on the following page.
Rigging Design Practices
Rigging a DRM18S requires determining:
1. The rigging methods and hardware that
meet static, shock, dynamic, and any other load
requirements for supporting the subwoofer
from structure.
2. The design factor and required WLL (Working
Load Limit) for this support.
We strongly recommend the following rigging
practices:
1. Documentation: Thoroughly document the design
with detailed drawings and parts lists.
2. Analysis: Have a qualified professional, such
as a licensed Professional Engineer, review and
approve the design before its implementation.
3. Installation: Have a qualified professional rigger
do the installation and inspection.
4. Safety: Use adequate safety precautions
and back-up systems.
