Notices
• When installing the product, a hole must be cut into the ceiling tile so the ceiling mount can be fixed in place. Remove the ceiling tile first if possible.
• To mount the threaded bushing in a ceiling tile without the isolators:
20.5 mm (0.81") diameter hole is required and the ceiling tile can be up to 22 mm (0.87") thick.
• To mount the threaded bushing with the isolators:
23.5 mm (0.93") hole is required and the ceiling tile can be up to 25 mm (0.98") thick. Place the isolators on either side of the hole to achieve mechanical isolation from the
mounting surface.
Installation
1. Remove the backplate of the ceiling mount and place it against the back of the ceiling tile, allowing the threaded bushing to pass through.
2. Once in place, thread the retaining nut onto the threaded bushing, securing the ceiling mount to the ceiling tile.
3. Connect the microphone cable to the terminal connector on the ceiling mount by pressing down the orange tabs on the terminal strip.
4. Once all connections are made, fix the remaining cable to the inside of the ceiling mount using the cable tie.
5. Adjust the cable to desired microphone height by either feeding or pulling the cable through the ceiling mount.
6. Once the microphone is in the desired position, gently turn the locking grommet clockwise to secure. (Do not over tighten and pull the cable strongly).
7. Coil the excess cable into the ceiling mount and replace the backplate.

Coverage examples
• For 360° coverage, create four hypercardioid (normal) virtual polar patterns at the 0°, 90°, 180°, 270°
positions. This setting is ideal for providing omnidirectional coverage of four people around a round
table (see Figure. A).
• For 300° coverage, create three cardioid (wide) virtual polar patterns at the 0°, 90°, 180° positions.
This setting is ideal for covering three people at the end of a rectangular table (see Figure. B).
• For installation of two or more units, we recommend that you install them at a distance of at least
1.7 m (5.6') (for hypercardioid (normal)) so that the coverage ranges of the microphones do not
overlap (see Figure. C).
