IMPORTANT INFORMATION SHOULD
YOU CHOOSE TO PAINT YOUR GRILLES
Because of its ultra-thin profile, the Vanishing
Series Sheer-Grille
™
requires a specific painting
procedure to ensure smooth, even coverage.
Important Note: Do not remove the grille
scrim before painting.
Paint Recommendation
We highly recommend you use a can of spray
paint matched to the ceiling color you want
the Sheer-Grilles to blend with.
Important Note: Never use a brush or
roller to paint the grilles, as this will clog
the perforated holes.
To paint the Sheer-Grille
1. Elevate the Sheer-Grille off of a flat surface.
This will ensure even coverage of the grille
frame and make it easier to pick up.
Mounting Idea: A single spray can cap
will raise the grille high enough.
2. Hold the spray paint about 12" from
the grille and at a 45° angle.
3. Apply one light, thin coat, moving evenly
side to side over the grille, then work your
way around the perimeter of the grille
to ensure you cover the grille frame.
4. After each application of paint, wait
approximately 1 minute, rotate the
grille 90°, and apply the next thin coat.
Important Note:Youmustrotatethegrille
90°. Use your hands to define the next 90°
rotation and always rotate the grille in the
same direction of travel.
5. Three light, even applications should cover
the grille and frame adequately. Remember
to work your way around the grille frame
to cover it evenly and completely.
ROOM ENVIRONMENT CONTROLS
Room Switch
If your listening room is very reflective, with
smooth sheetrock walls, hardwood floors and
non-cushioned furniture, the sound will be
overly “bright” and unnatural.
Engaging the Room Switch (Reflective) compen-
sates for the effect of reflectivity in a “hard room”
by attenuating only the portion of the tweeter
response that can cause harshness resulting
in listener fatigue. This flattens room response
without hindering higher frequency response,
for warmer, more realistic sound and more
accurate imaging.
If your listening room is not highly reflective,
that is it has curtains, carpeting, and cushioned
furniture, leave the Room Switch in its Normal
setting (Norm).
Wall Distance Switch (LS models only)
In-ceiling loudspeakers excel when placed
more than 2' (60cm) from side walls. If position
limitations demand that in-ceiling loudspeakers
be installed closer than 2' (60cm) from side walls,
the proximity of the surface can result in a response
“bump” between 50Hz and 200Hz. This can cause
in-ceiling speakers to sound “boomy.” The
“Wall Distance” switch flattens response
and eliminates “boominess” without sacrificing
deep bass response, for more lifelike sound.
