with high quality components, innovative technologies and special assembling
methodologies, which allow to function properly also when it’s plunged into saline water
or water with high chloride content.
USE
This underwater speaker allows listen to music and voice clearly.
Aquarmony helps every sports session to get more interesting and motivating, encourages and supports the
game, the animation as well as the relaxation in your swimming-pool.
It can be used for synchronized swimming, relaxing activities, prenatal swimming classes, swim lessons for kids,
and any sorts of game in swimming-pool.
It’s particularly suitable for the water relaxing activities and for all the therapies with the patient relaxed in the

INSTALLATION
About its installation, it is very simple to install Aquarmony as it is available in two versions: for the swimming
pools that are already operating and for the swimming pools under construction.
About the first version, it does not require any intervention as the underwater speaker is plunged into water by a
cable and connected to the amplifier system. It is pulled out of the water after its utilization.
Concerning the fixed installation for the swimming pools under construction, Aquarmony is set in the lamp niches.
The loudspeaker can be supplied with the assembling kit in order to make its installation very easy. Moreover,
Aquarmony is provided with the plastic rings to be set better into the niche.
Aquarmony speaker works at best if the middle
of the niche is at 40 cm from the water surface.
In any case, it’s advisable not to install the
loudspeaker at more than 60 cm under the water
level.
Aquarmony must be completely plunged into
water; It doesn’t spread music outside water.
To spread music outside water it’s necessary to
install loudspeakers appropriate to the
environment and to the specific requirements.

Aquarmony installation example in concrete pools
Put on the neoprene cable in the flexible pipe up to reach the junction box, giving attention that the cable gland
and the gasket are well embedded.
Be sure to have at least 1 m cable length wrapped in the niche in order to be able to carry the loudspeaker on the
edge of the pool.
Screw the cable gland inside the niche by using the provided gasket; screw the cable gland of the junction box
too.
Insert Aquarmony in the niche and be sure that the plastic ring is perfectly adhered to the wall.
Finally, screw tighter the plastic ring to the wall so that the loudspeaker is perfectly fixed in the niche.
The electric wire joining the junction box to the amplifier system must not be smaller than mm2 2 x 2,5 size.

Particular cases:
1) If the swimming pool is prefabricated with PVC lining or manufactered with other
soundproof materials the quantity of loudspeakers and that of the amplifiers must be
doubled
2) If the swimming pool is near the water plays or whirlpool baths it’s necessary to
increase the quantity of loudspeakers in order to make their sound louder than the
background noise
3) If the loudspeaker is mobile, that is it’s plunged into water by a cable, the values
indicated in the table above remain valid only if the loudspeakers are not deeper than
40 cm from the surface.
The electric wire joining the junction box to the amplifier system must not be smaller than mm2 2 x 2,5 size.
For an accurate system it’s obligatory to respect all the devices provided by the law: electrical insulation, max 12
V cc power supply on the pool surface.
Aquarmony loudspeakers must be connected to the amplifier system by the isolating transformers (see the
picture): AQTR1004 for the audio systems with fixed voltage, AQTR44 for 4 ohm audio systems.

AQUARMONY Specifications and owners’ manual
It’s very important that the amplifier system has an equalizer and a limiter or compressor in order to protect the
loudspeaker form excessive power.
In particular, all frequencies under 300Hz must be attenuated by at least 12 dB to reduce distortion and to prevent
the voice coil from overheating, and frequencies above 2000 Hz should be amplified by at least 10 dB.
It’s important to calibrate the limiter in order to prevent saturation of the amplifier and prevent the loudspeakers
from passing 60w RMS.
As you cannot listen to music outside water if you haven’t a limiter you cannot control the sound volume, so the
loudspeakers may be damaged.
