Design Note:

Sound masking speakers are typically mounted above the

finished ceiling in the plenum space. In most installations, the sound masking

speakers are installed with the bottom of the enclosure roughly 1' above the

finished ceiling with the speaker aiming upward so the masking noise bounces

off of the slab or deck above. When the plenum space is taller than 6', the

designer may decide that the sound masking speakers should be installed at 6'

or more above the finished ceiling aiming downward. In some instances,

plenum spaces crowded with many obstructions may require that the speakers

be mounted sideways aiming between the obstructions. For other applications,

the designer may choose to rest the masking speakers directly on the lay-in tile

ceiling grid. The exact mounting position of the masking speakers dramatically

affects the dispersion of the sound masking noise. This installation sheet has

been written under the assumption that a qualified consultant or designer has

pre-determined the speaker spacing and mounting orientation that will result in

the desired sound masking noise coverage.

As shipped from the factory, the masking speaker hangers are configured

for aiming the speaker upward. Unfold the speaker hangers as shown.

For models SM810A-BR, SM820A-BR, and SM410A-BR skip to step.6

To install the masking speakers aiming sideways or aiming down, it is

necessary to remove the hangers. To remove and reinstall the hangers, always

rotate the hanger to the 45 degree position as shown. Note: If placing the

speakers under a computer floor or on a shelf, remove and discard the hangers.

To install the speaker aiming sideways, remove the hangers by rotating

them to the 45 degree position. Relocate the hangers to the 45 degree position

in the new location and reinsert the hangers as shown.

To install the speaker aiming downward, remove the hangers by rotating

them to the 45 degree position. Relocate the hangers to the 45 degree position

in the new location and reinsert the hangers as shown.
