Consider the following when choosing a mounting height:
•
The pickup pattern of the ceiling array is narrower than a shotgun microphone, so it can be placed farther from sound
sources. There is no specific barrier at which the audio degrades or gates off.
•
Like all microphones, tonality changes as the distance from the source increases.
•
The pickup area of the microphone increases slightly as it is mounted higher.
Square Mounting Options:
•
In a ceiling grid
•
With a VESA mounting device
•
On NPT pole
•
Suspend from ceiling with A900-GM
•
Suspend from ceiling with your own hardware
•
On 3/8-inch threaded rod
•
Attach to ceiling with A900-CM
•
In a hard ceiling
Round Mounting Options:
•
With a VESA mounting device
•
On NPT pole
•
Suspend from ceiling with A900-GM
•
Suspend from ceiling with your own hardware
•
On 3/8-inch threaded rod
•
Attach to ceiling with A900-CM
Installing in a Ceiling Grid
Before you begin:
•
Remove the plastic cover from the microphone.
•
If using, install the rubber pads on the corners of the microphone to prevent scratches.
•
Verify that your ceiling grid size matches your model variation.
•
If using the A910-JB junction box, install it before ceiling installation.
IMPORTANT: Do not install the 60 cm model in a 2 foot (609.6 mm) ceiling grid.
1.
Make space in the ceiling grid for the array microphone to be installed.
2.
Route the Ethernet cable above the ceiling grid and through the opening in the ceiling.
3.
Plug the Ethernet cable in to the microphone.
4.
Attach the safety tether between the building structure and one of the tie-off points on the back of the microphone using
braided metal cable or other high-strength wire (not included). This safety measure prevents the microphone from
falling in an emergency situation. Make sure there is no tension on the safety tether. Follow any local regulations.
5.
Install the microphone in the ceiling grid.
