Introduction
This system uses Industry Spa Tactile Transducers, connected to a Bluetooth Amplifier,
producing brilliant “Hidden Sound”.
Tactile Transducers work by transferring their energy into the material they are attached to.
As the surface becomes the sound board they work better with dense materials such as
wood and plasterboard. However, we have found good results with Acrylic Baths and
Shower Walls.

Installation Guide
Affix the transducer plates to your chosen surface using either epoxy resin or screws.
Fix the transducers to the plates using the fixing bolt provided.
Plug the Red & Black connections into the rear of the amplifier.
Plug the amplifier in and power on. We recommend setting the volume to 70%.
Turn on your music device (phone, etc) and SEARCH for Bluetooth devices. You can now
PAIR to the amplifier.
The plug socket needs to be located in a dry area, i.e., an adjacent room, in the loft or
under the bath. If installing under a bath, a bath panel must be securely fixed.
Volume can be controlled via your phone.
The Amplifier should be located where it can best receive the Bluetooth signal, in a
dry and ventilated area.
If using in conjunction with our Bathroom TV, then connect a cable from the Audio jack
to the Red & White Audio connectors on the rear of the TV.
Other applications:
These waterproof transducer speakers can also be fitted behind ceilings, walls, cupboard
doors, for a truly hidden home theatre experience. No unsightly speakers visible
anywhere!
Home theatre (use in conjunction with subwoofer), museums, exhibits, displays, spas,
message therapy, ceiling tile PA, tactile therapy and many more limited only by your
creativity!
When fixing to a wall, ceiling, etc, the speaker should be screwed to the back of the
substrate, using appropriate fixing screws. As a substrate, we recommend half-inch
plywood for best results.
