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.
SRMv3 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 SPM200 is a great
option when using a subwoofer.
These loudspeakers may also be flown via their
integrated fly points as detailed on page 15. Be sure
to read the PA-A1 Eyebolt Installation Instructions,
as well.
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.
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.
SRMv3 loudspeakers are NOT designed to array
horizontally. If you feel you must put two speakers
side-by-side, you should have a good understanding
of the relationship between the splay angle (the angle
between the facing sides of the cabinets) and frequency
cancellation effects between cabinets.
When two cabinets are positioned side-by-side
such that the rear-angled faces of the enclosures
are parallel, the splay angle will be 90º. This matches
the 90˚ horizontal coverage pattern of each individual
loudspeaker; the interference between the two cabinets
will be minimized, but the total coverage of 180˚ may
be too wide for some applications. The mid and high
frequencies may also be reduced for those in the center
who are too close to the loudspeakers.
Reducing the splay angle will reduce the total
horizontal coverage, but it also creates an area both
speakers are covering. Instead of a nearfield hole,
this will cause comb-filtering effects in the frequency
response in the overlapping area. The smaller the splay
angle, the more energy will be delivered on-axis, but the
comb-filtering effects will get worse at the same time.
To reiterate, though, we strongly suggest
NOT arraying these loudspeakers horizontally.
Experimentation and experience will help you find
the right balance for your application.
