Coverage Angles

Before mounting the loudspeaker, determine the mounting orien- tation and desired coverage angles. As supplied from the factory, the loudspeaker’s coverage angles are 90° (horizontal) x 60° (ver- tical) with the cabinet oriented vertically. The waveguide can be rotated to interchange the coverage angles.

Rotating the Waveguide to Alter HF Coverage Pattern

1- Remove the grill. Gently and evenly work the grill out of its retaining groove to avoid bending the grill.

2- Remove the eight waveguide retaining screws. A #2-size Phil- lips screwdriver is recommended.

3- Reach into the waveguide’s port and pull gently to remove the waveguide. Be careful not to damage the connections, wiring, or the gasket between the waveguide and the cabinet.

4- Rotate the horn 90° clockwise or counter clockwise and set it back in place. Make certain the wiring is not stressed or pulled loose from its connections.

5- Before reinstalling the waveguide screws, lift the assembly a small distance and make sure that the gasket is properly in place. Reposition it, if required. Set the waveguide in place and reinstall the screws. Do not overtighten.

6- Replace the grill.
