4.8.641 Positioning and Horn Rotation

The 41 can be positioned in several ways. When used as a floor monitor either of the two backs may be placed on the floor to vary the aiming angle. One provides an up-angle of 30 degrees from the floor and the other an up-angle of 45 degrees from the floor. The 41 may also be used upright as a PA loudspeaker.

The 41 is shipped from the factory oriented for floor monitor use so that, in a horizontal position, its HF coverage is 90 degrees horizontal by 40 degrees vertical. For operating it in an upright position as a PA loudspeaker, normally the horn should be rotated so its horizontal coverage pattern will be 90 degrees. (See SECTION 7.3)

4.8.7Front Grille

The front grille is powder coated, 16 gauge perforated steel, held in place with screws. This provides a secure fastening while allowing easy removal for service.

4.8.8Enclosure Finish

XLT: The XLT enclosures are finished with a dense, black carpet material held in place with an industrial strength adhesive backing.

XLTE: The XLTE enclosures are finished with a black, high durability urethane coating.
