General aiming and placement guidelines
Loudspeakers should be pointed at the people and away from reflective room surfaces. Since
people are excellent absorbers of sound and room surfaces are often not, this practice
ensures not only that the audience will perceive the high frequencies necessary for good voice
and musical clarity, but also that acoustic reflections do not excessively degrade intelligibility.
Loudspeakers for sound reinforcement are usually located above a stage or platform and
aimed down and out into the audience. This minimizes the difference between the longest
throws to the rear of a venue and the shortest throws to the front rows, promoting uniform
coverage. Note that a typical portable loudspeaker on a short, 6-foot stand cannot duplicate
such uniformity since the distant seats are so much farther away than the front rows. The
direct sound from a loudspeaker drops 6 dB every time the distance from it doubles,
according to the formula:
Level loss (dB) = 20log
10
(closest distance/farthest distance).
Preparing the EVC loudspeakers for installation
Unpacking and inspection
Carefully open the packaging and take out the loudspeaker. Inspect the loudspeaker's
enclosure for any damage that might have happened during transportation. Each loudspeaker
is examined and tested in detail before leaving the manufacturing site. Please inform the
transport company immediately if the loudspeaker shows any damage. Being the addressee,
you are the only person who can claim damages in transit. Keep the cardboard box and all
packaging materials for inspection by the transport company.
Keeping the cardboard box including all packing materials is also recommended, even if the
loudspeaker shows no external damage.
When shipping the loudspeaker, make sure to always use its original box and packaging
materials. By packing the loudspeaker exactly as it was packed by the manufacturer, you will
guarantee optimum protection from transport damage.
Scope of delivery
Keep the original invoice that states the purchase/delivery date in a safe place.
Recommended pre-installation procedures
For any sound system, certain checks made at the installer’s place of business can prevent
expensive on-site delays. EV recommends that you take the following steps:
1.
Unpack all loudspeakers in the shop.
2. Check for proper model numbers.
3. Check the overall condition of the loudspeakers.
4. Check for continuity at the loudspeaker inputs.
