Principle

The Asymmetrical Dispersion Constant Directivity horn is an important feature of the PS Series. This concept was previously
only available for highly specialized applications; in the general purpose PS it is fully exploited thanks to a practical design that
makes user configuration of the horn practical and quick.
The proper configurations of the horn for two common applications are shown below. All 4 positions of the horn are possible
and can be useful for specialized applications such as complex arrays, systems designed with CAD software and stage
monitoring.
The specific dispersion of the PS8, PS10R2 & PS15R2 horn can be seen on the figure in the "front of house" configuration
section:
•
As seen on the side view, vertical coverage is narrower above horn axis (+25°) than below (-30°).
•
As seen on the front view, horizontal coverage is narrower above horn axis (50° Horizontal for +25° Vertical) and wider
below (100° Horizontal for -30° Vertical). Between these two extremes horizontal coverage varies according to a
specific law; on axis (0° Vertical) coverage is 75° Horizontal.

Change of configuration

Access to the horn for configuration and checking is easily made by removing the front grille (4 TORX screws to be removed
top and bottom of the cabinets). To modify horn orientation, remove the four Allen 4 metric or TORX TX25 screws that hold the
horn in place A sticker on the wide dispersion side of the horn shows the correct orientation for wedge monitoring and front of
house applications: you simply position the indication on the desired side. The arrow indicates the wide dispersion.
