Safety First
When setting up, installing and using Electro-Voice
®
Sx
A
speaker systems, there are a
number of precautions that you should follow:
·
When Electro-Voice
®
Sx
A
speakers are used for portable applications in which they will be
stacked directly on the floor or mounted on a tripod stand, make sure that the floor or
stage is solid and secure.
·
Electro-Voice
®
Sx
A
speaker systems include 1 3/8-inch stand mounts to allow mounting on
tripod stands.
Make sure to:
·
Check the specifications of the speaker stand to be certain it is capable of supporting the
weight of the speaker.
·
Check that the speaker stand is placed on a flat, stable surface and be sure to fully extend
the legs of the stand. Do not try to make the stand “taller” and compromise its structural
integrity.
·
Route cables and position the stand so that performers, production crew and audience
members will not trip over the stand or cables and pull the speaker system over. Secure
cables with wire ties or tape whenever possible.
·
Do not attempt to suspend more than one speaker on a stand designed for a single
speaker.
·
Unless you are confident that you can safely handle lifting the weight of the speaker onto
the stand, ask another person to help you place it.
·
After the system is in operation for a few minutes, the heat sink will become warm to the
touch and can become quite hot after extended high-level operation. Avoid touching the
heat sink fins to prevent burns. When installing the system, use care to ensure that there
is at least two inches of space behind the heatsink to allow free circulation of air.
·
If you intended to hang or fly the
Sx
A
two-way systems, please do so safely with the correct
hardware and accessories.
WARNING:
Suspending any object is potentially dangerous and should only be
attempted by individuals who have a thorough knowledge of the techniques and
regulations of rigging objects overhead. Electro-Voice
®
strongly recommends that
Sx
A
speakers be suspended taking into account all current national, federal, state and local
regulations. It is the responsibility of the installer to ensure that
Sx
A
speakers are safely
installed in accordance with all such regulations. If
Sx
A
speakers are suspended, Electro-Voice
®
strongly recommends that the system be inspected at least once a year. If any sign of weakness
or damage is detected, remedial action should be taken immediately
. Please consult our
manual entitled
Suspending System 200 Loudspeakers
, and the SK1 data sheet, which details
the various hardware kits that are available to safely suspend
Sx
A
speakers and how each kit
should be used. There are also data sheets for each EV hanging hardware part that should
also be consulted prior to suspending speakers.
·
Electro-Voice
®
does not recommend use of
Sx
A
speakers outdoors or in high
moisture environments. Avoid exposing
Sx
A
speakers to direct moisture and or
high humidity that can cause corrosion of electrical contacts and problems with
loudspeaker cones and surrounds.
·
Electro-Voice
®
Sx
A
loudspeakers are easily capable of generating sound pressure
levels sufficient to cause permanent hearing damage to anyone within normal
coverage distance. Caution should be taken to avoid prolonged exposure to sound
pressure levels exceeding 90 dB.
