Fig.14. Live applications
To obtain a clear and free-distortion reproduction, it is advisable to place the mid-high
units on top of the low units keeping between them an approximate height of two
meters. If such height cannot be achieved nor maintained, it is advisable to use the
classical tripod for each mid-high cabinet and leave the low units on the floor.
3.4. Asymmetrical and rotatable horns
The P-10A / P-12A / P-15A / P-15SMA models incorporate an asymmetrical
dispersion horn which will optimise coverage either in horizontal or vertical position.
To rotate the horn, unscrewed the frontal grille, and then, unscrewed the four fixing
screws of the horn. Rotate it 90 degrees taking care of the wires. Screw the horn
again and finally place the frontal grille in its right position.
Fig.15. 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
distances the horn should be used with its "wide" dispersion (100º). For long
distances the horn should be used with its "narrow" dispersion (50º).
We suggest to pay attention to the following examples.
