Electro-Voice UW30 EDS User Manual

General Product Description

The UW30 represents a departure in the design of
underwater sound sources. Its unique design, U.S. Patent
#3,670,299, utilizes the case’s structural enclosure as the
sound transducer. This development makes possible a
speaker that has no metal parts exposed to the outside,
thus eliminating rust, corrosion or other causes of short-life
expectancy. The transducer principle and its strong
construction allow the UW30 to operate at much greater
depths than any prior type of underwater loudspeaker design.
The 12.7-ounce ceramic magnet and state-of-the-art
voice-coil construction ensure full-fidelity response with the
lowest possible distortion throughout its power range.

The UW30 is equipped with a waterproof, 3 conductor 15.24
m (50-ft.) cable. The UW30-100 features a 30.48 m (100 ft.)
cable.

The UW30 underwater loudspeaker is designed for
permanent installation and completely submerged operation.
All internal components are encapsulated with a “hot-melt”
(Polyamide Copolymer) process. The outer case is
constructed of high impact ABS (Acrylonitrile butadiene
styrene) plastic. Ideal for installation in both fresh and
saltwater pools, the UW30 can even be installed in ocean
environments without adverse effect. Problems such as
corrosion and electrolysis damage inherent in all or partial
metal underwater speakers are completely eliminated by the
plastic construction of the UW30.

A single model UW30 will deliver uniform sound throughout
moderate pools, up to 30 by 30 feet. For larger pools, up to
30 by 60 feet, two speakers should be used. If a high level of
turbulence is to be overcome, such as swimming and diving
instruction classes, several speakers should be used. The
noise level in the water will not only be more effectively
overcome, but it will also allow each speaker to be operated
at a lower power level thus avoiding excessive sound
intensities in the immediate vicinity of the speakers.

Underwater speakers are required equipment for many
activities in commercial and luxury resort pools. As specified
by the American Athletic Union, underwater speakers are
required for synchronized swimming events and instructions
in Olympic pools. They are used for water ballets and similar
water shows. When underwater speakers are installed in
resort and private pools, the effect of music played
underwater is truly an enchanting experience.

Installation

Flush Mounting

For new pool construction and modification of older pools, installing
the UW30 flush with the sides of the pool makes a very neat and
unobtrusive installation. The speaker is mounted in a wet-niche
(Paragon Part #68102 or equivalent) in the same manner as an
underwater light. Figure 1 shows a typical installation. The speaker
is mounted up to 1.2 m (4 ft.) below the surface of the water and
flush with the side of the pool. (For installation in water depths lower
than recommended, please contact factory.) A marine plywood or
stainless steel mounting ring or face plate is recommended.
(Paragon Part # 6810355 stainless steel or #68103 bronze polished
chrome or equivalent). Several pool equipment manufacturers have
wet-niches available into which the UW30 may be installed. See
your local pool supplier for further information. You may contact

Fusing

For maximum protection against speaker overload, fusing the line
from the amplifier is recommended. In the event of accidental
overload, it is much easier to replace a fuse (which is above the
water) than to replace or have the speaker repaired. Installing a 25
ohm, 20 watt resistor in parallel with a 1.5 ampere, fastblowing
fuse in series with the speaker is recommended. See Figure 2.

Layout of Speaker in Pool

When underwater speakers are installed, particularly in smaller
pools where only one or two speakers are needed, they should be
located in the deep end of the pool. The above recommendation
will effectively equalize the intensity of sound throughout the pool.
For installations in large pools, such as at country clubs, municipal
facilities, etc., the speakers should be located around the periphery
of the pool. A good rule to follow for large pools is one speaker for
every 900 square feet (83.61 square meters) of pool surface at the
deep end and one speaker for every 1,200 square feet (111.48
square meters) of pool surface for the shallow end. Of course, for
high-noise conditions in the pool, the number of speakers should
be doubled for best results.
