High Humidity Grille
Installation Guide
Biamp offers several sizes of High Humidity Grilles (GHH) suitable for
the Desono CM ceiling loudspeakers. They are sold in 6-packs and can
be installed on the ceiling loudspeaker by substituting the high humidity
grille for the grille included with the unit. Please refer to the appropriate
Installation and Operation guide for full installation instructions.

Installation

1. Install the loudspeaker without fully tightening the dog ears -
leaving 5-8mm gap between the ceiling and loudspeaker face.
Adjust tap settings as necessary.
Note: If the unit has been previously installed, remove the grille and
lower the unit (about 5-8mm) by raising the dog ears.
2. Insert a spacer on each side between the ceiling and
loudspeaker rim. Orient them so the tab fits into the recess on the
opposing one- see circles in the spacer detail.
3. Support the loudspeaker and tighten the dog ears to clamp the
spacers against the ceiling.
