SOUND CUTS OUT OR IS DISTORTED

Most models of LineaResponse invisible speakers contain self-resetting limit switches for protection against excessive



amplifier output. These switches respond to the heat generated from the excessive volume output and will be triggered before

output reaches levels that could damage the speaker. Sound quality may be greatly reduced as the limit is approached but

the speaker and amplifier will not be damaged. Once fully triggered, audio output will cease until the excessive volume has

been corrected and the limit switch returns to it's normal operational state (approximately 5-10 minutes).

Some speakers may contain up to three independent switches: high-frequency, low frequency, and mid-range frequency.



Depending on the frequencies in the audio being played one or more limit switch may be triggered while the remaining

frequency ranges may continue to output normally. In any case, pause the audio or reduce the volume level until the limit

switches have returned to their operational state.

SOUND IS MUFFLED

Muffled sound from an LineaResponse speaker is almost always a sign that too much material was applied to the face of

I CAN SEE THE SPEAKER

By following the instructions in this document it is possible to achieve a completely invisible installation of the



LineaResponse speaker. Experience with wall finishing techniques and skills are helpful, but with patience and a keen

eye for detail a handy homeowner can achieve satisfactory results. If a speaker is installed in a hurry or without care

it will be visible even after texture and paint have been applied. Applying additional wall finishing compound or other

materials to cover an improper installation may correct the visibility of the speaker but will likely impact sound quality.

Contact your Stealth dealer or Stealth Acoustics directly if an installation repair is necessary.

On the larger sized models of LineaResponse speakers installations in ceilings (or sometimes walls) can be adversely



affected by improperly skimming mud over the entire speaker face. Although the transition may appear smooth, the

extra weight of the material in the center of the speaker can cause it to deflect and a "pillowing" effect may be visible.

Excess material should be sanded away carefully.

In rare cases lighting conditions may generate sheer lighting down/across the installation location at a very low angle.



This can cause even very small irregularities in the finish to cast a shadow and appear to be larger than they are. Care

in planning speaker locations can help prevent this situation, as well as using a flashlight to generate sheer light during

the installation process to check and correct any problems as they might arise.
