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: You must rotate the grille

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

Reflective / Norm

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 Dist.

<2' >2'

(60cm) (60cm)

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.
