4.MOUNTING AND PLACEMENT
4.1.Asymmetrical and rotatable horn
The SM-12D8 incorporates an asymmetrical dispersion horn which will optimise
coverage depending on the needs of the installation.
To rotate the horn, unscrewed the frontal grille, and then, unscrewed the four fixing
screws of the horn. Rotate it 180 degrees taking care of the wires. Screw the horn
again and finally place the frontal grille in its right position.
Fig.6. Rotatable horn
Good coverage of audiences often is a conflicting combination of:
*wide coverage for the closest audience (short throw)
*narrow coverage for distant areas (long throw)
The asymmetrical dispersion horn coverage varies from "short throw" to "long throw"
along the vertical axis (keeping a constant vertical directivity). In conclusion,
directivity feature of (50º to 100º(H), 55º(V)) can be seen as if the horn itself had "two"
horizontal directivities (audience coverage), which depend on the distance. For short
