APPENDIX A: MEYER SOUND WEATHER PROTECTION
The Weather Protection option from Meyer Sound is
intended to increase the useful life of Meyer Sound
loudspeakers when they are installed outdoors and exposed
to different and often harsh weather conditions. Our
Weather Protection includes a penetrating treatment to raw
wood, use of special primers, and plating on all steel parts
used (or alternatively, the use of stainless steel hardware).
Weather Protection is designed to prevent malfunctions
caused by harsh operating environments and slows the
accelerated wear and tear that occurs in outdoor
environments.
When Is Weather Protection Advisable?
Weather Protection is strongly recommended for all
permanent outdoor installations where loudspeakers are
directly exposed to the elements. This includes desert and
semi-arid climates, where protection against dust and sand
is important, and where infrequent rainstorms can
contribute to deterioration of loudspeaker components.
Weather Protection is also recommended when the
loudspeakers are sheltered from direct exposure to
precipitation but are nevertheless exposed to prolonged
high humidity, fog or mist. Examples would be installations
on covered outdoor terraces or pavilions.
Weather Protection is further advisable for portable or
touring systems when any significant outdoor use is
anticipated. Even though standard procedures may call for
using external protective measures, these are often not
implemented in time to prevent moisture intrusions that
could lead to premature performance degradation of the
loudspeaker.
Climate Variation and Owner Maintenance
The wear and tear on a loudspeaker will vary significantly
with different climatic conditions. For example, a weather-
protected loudspeaker installed in a sunlight-exposed
location on an ocean pier will experience much harsher
conditions than a loudspeaker in a similar installation that is
shaded by trees and exposed only to rainfall. The constant
exposure to direct UV radiation and salt air environment will
cause a loudspeaker to wear more quickly than one with
partial UV shielding and exposed only to freshwater
moisture.
Wear can eventually affect the performance of the
loudspeaker. It also affects aesthetics. For example, in salt
air environments, the exterior grille can quickly show signs
of oxidation, causing unsightly discoloration.
Apart from selecting suitable weather protection, the
progress of wear and tear on the loudspeaker can be
slowed by a regular schedule of inspection and cleaning.
This maintenance is particularly necessary in harsh
environments. Inspection and cleaning should include
routine removal of any visible oxidation or environmental
particulates, as these can accelerate metal corrosion or
decay of the cabinet. If installed loudspeakers are not in use
for an extended period, exterior protection or temporary
removal and storage of the loudspeakers should be
considered.
Benefits of Weather Protection
There are several benefits to selecting the Meyer Sound
Weather Protection option:
Functionality - Weather Protection prolongs the service life
of the loudspeaker by preventing premature degradation of
internal components.
Safety - Weather Protection lessens the chance of electrical
malfunctions or structural failures.
WARNING:
IT IS THE RESPONSIBILITY OF
PURCHASERS/USERS/OPERATORS TO
SELECT WEATHER PROTECTION WHEN APPRO-
PRIATE FOR THEIR USE AND TO PERIODICALLY
INSPECT THEIR LOUDSPEAKER INSTALLATIONS
FOR ANY DETERIORATION THAT MAY LEAD TO
SAFETY CONCERNS.
Aesthetics - Weather Protection slows wear and tear on the
exterior of the loudspeaker in harsh conditions. Early signs
of wear and tear on the exterior of the loudspeaker indicate
over-exposure to the elements.
Standards Compliance - Weather Protection helps in
meeting IP ratings for loudspeakers. IP ratings are an
internationally recognized standard often used in
installations involving our products. A further explanation of
IP ratings is given in the "IP Ratings Definition Chart"
Section on page 35.
