Preparing the EVU for Installation
Rotation of the High-Frequency Waveguide Sub Assembly
All high-frequency waveguide sub assemblies have their horizontal and vertical patterns molded on the front of the waveguide
for easy identification of orientation. The high-frequency waveguide sub assembly can be rotated to change the high frequency
pattern.
NOTE: The high-frequency waveguide sub assembly is installed at the factory with the 90° wave pattern oriented along
the long axis of the enclosure for all models.
To change the high-frequency waveguide sub assembly’s orientation , do the following:
Tools: #2 Phillips screwdriver
1.
Remove the eight (8) screws (A) from the top and bottom of the grille.
NOTE: The grilles on the single woofer models, EVU-1062 and EVU-1082, use six (6) screws.
2.
Remove the grille (B).
3.
Remove the eight (8) screws (C) holding the high-frequency waveguide sub assembly.
4.
Rotate the high-frequency waveguide sub assembly 90° (D) until the desired pattern (90° or 50°) marking is located
along the long axis of the enclosure.
5.
Reinstall the high-frequency waveguide sub assembly (D) with eight (8) screws (C).
6.
Reattach the grille (B) to the front of the loudspeaker (E).
