    Attaching Microphones to 3/8 in. Threaded Rod

    To get started, you will need:

    • A900-PM-3/8IN kit
    • 3/8 in. diameter threaded rod and hardware to attach to ceiling*
    • Ethernet cable*

    *Not included

    1. Install the threaded rod on the ceiling according to manufacturer's instructions. Route the Ethernet cable down the side of the threaded rod.
    2. Thread the jam nut onto the threaded rod.

    4. Partially thread the thumb screws into the microphone.

    5. Lift the microphone and align the thumb screws with the holes in the VESA bracket. Tighten the thumb screws to secure the microphone to the VESA bracket.

      Important: Before tightening, make sure that the thumb screws are properly seated in the VESA bracket.

      When installing on short poles, it's easiest to check alignment from the side with the enclosed keyholes.

    6. Rotate the microphone to your preferred position. Tighten the VESA bracket's set screw with the Allen key to lock the position.

      Turn the VESA bracket to change the position of the MXA901. Then use an Allen key and set screw to lock the position of the VESA bracket.

    7. Connect the Ethernet cable to the microphone. Secure the Ethernet cable to the threaded rod with the cable ties.
