Ac Power; Care And Maintenance; Placement - Mackie DRM212 Owner's Manual

AC Power

Be sure the DRM loudspeaker is plugged into
an outlet that is able to supply the correct voltage
specified for your model. It will continue to operate
at lower voltages, but will not reach full power. Be sure
the electrical service can supply enough amperage for
all the components connected to it.
We recommend that a stiff (robust) supply of AC
power be used because the amplifiers place high
current demands on the AC line. The more power that
is available on the line, the louder the speakers will play
and the more peak output power will be available for
a cleaner, punchier bass. A suspected problem of "poor
bass performance" is often caused by a weak AC supply
to the amplifiers.
Never remove the ground pin on the power
cord or any other component of the DRM
loudspeaker. This is very dangerous.

Care and Maintenance

Your DRM loudspeakers will provide many years
of reliable service if you follow these guidelines:
• Avoid exposing the loudspeakers to moisture.
If they are set up outdoors, be sure they are under
cover if rain is expected.
• Avoid exposure to extreme cold (below freezing
temperatures). If you must operate the loudspeakers
in a cold environment, warm up the voice coils slowly
by sending a low-level signal through them for about
15 minutes prior to high-power operation.
• Use a dry cloth to clean the cabinets. Only
do this when the power is turned off. Avoid getting
moisture into any of the openings of the cabinet,
particularly where the drivers are located.

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 loudspeaker is installed in a stable and secure
way in order to avoid any conditions that may be
dangerous for persons or structures.
DRM loudspeakers are designed to sit on the floor or
stage as the main PA or as monitors. They may also be
pole-mounted via the built-in socket on the bottom of
the cabinet. Be sure the pole is capable of supporting
the weight of the loudspeaker. The SPM400 is a great
option when using a subwoofer.
These loudspeakers may also be flown via their
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 DRM
loudspeaker 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
loudspeaker(s).
When pole-mounting loudspeakers, be sure that they
are stabilized and secured from falling over or being
accidentally pushed over. Failure to follow these
precautions may result in damage to the equipment,
personal injury, or death.
The DRM212 and DRM215 have dual angle
pole-mounts for optimal coverage. The rear one
is a straight angle while the front is angled at a 7˚
downward tilt. Additionaly, these two models may
be laid out horizontally as monitors for the band
at a 50˚ angle (as seen below).
The Running Man logo is rotatable for
when the DRM212 or DRM215 is used
as a monitor; you can also rotate it when
the DRM315 is flown horizontally!
As with any powered components, protect them from
moisture. Avoid installing the loudspeaker in places
exposed to harsh weather conditions. If you are setting
them up outdoors, make sure they are under cover if
you expect rain.
