Maintenance and cleaning
Once your Evolution Series speaker is plastered into your wall or ceiling, it requires no physical
maintenance. Your wall or ceiling can be cleaned with products appropriate to the finish finally
applied to the plaster surface.
The wall or ceiling can be painted or redecorated any number of times. Extreme care should be
taken when removing wallpaper type coverings to ensure the plaster surface is not damaged. If
damage to the plaster work occurs, use repair plaster to restore the plaster surface prior to re-
decorating. Amina Technologies Ltd recommends British Gypsum Easi-fill® repair plaster.
Avoid pushing the wall or ceiling surface immediately in front of the speaker. Excessive
excursion, whilst unlikely to damage the speaker, will undoubtedly cause the plaster to crack
around its perimeter.
Reliability
Correctly installed and used within its specification, the Amina Evolution Series speaker is
designed to give many years of trouble-free service. The vibrational soundboard technique
used by the Evolution Series has very few moving parts. Compared to a conventional
moving coil speaker these movements are insignificant. Whilst the human touch can feel
the tiny movements, they cannot be seen by the naked eye. Such small movement of this
electromechanical structure means the long term reliability is enhanced compared to the much
larger movements of conventional loudspeakers.
Removal
In the unlikely event of a problem developing with the product, or you simply wish to remove
the item to change its location, please refer to the following guidelines:
Locate the speaker by tapping the wall or ceiling listening for a hollow sound compared to the
rest of the wall/ceiling. Then, with a sharp chisel or decorator’s scraper, carefully chip into the
plaster along the edge of the speaker to expose a small area of the panel surface. To ensure
you do not damage the panel, hold the tool at an acute angle to the wall or ceiling.
Now, holding the scraper almost parallel to the panel surface, work outwards towards the
products’ corners easing the plaster away from the panel (during this process, attempt to
remove as little plaster as possible). Do not worry if the panel surface receives marks or
indented scratches during this process (it should not, however, have holes entering through
to the unique honeycomb panel). Once the product is plastered back into its original or
new location, the new skim of plaster will cover all these imperfections and the speakers
performance will not be unduly affected.
Clear the surface plaster material from the surrounding plasterboard to expose all the joint
tape and subsequently remove it. Use a narrow chisel or flat blade screwdriver to remove the
plaster and expose the screws at each corner of the product. Using a suitable screwdriver,
remove the four screws and then ease the product from the wall or ceiling and disconnect
the speaker cable. Leave all four fixing blocks or the BackBox in place as these can be used to
support a small section of plasterboard when making good the wall/ceiling.
If the product needs repairing, please return it to your supplier or Amina Technologies Ltd
again leaving as much plaster on the panel surface as possible. Once repaired, the product
can be refixed into position following appropriate installation steps detailed earlier within the
manual.
