Ceiling Microphone Lifter

1.) Install the mounting plate above the bottom of the finished ceiling so the ceiling bezel will be flush with the bottom surface. Use ½” nuts/bolts/washers. Attach to structural channel or other solid mounting surface. Be sure the plate is level: front-to-back and side-to-side.
2.) Remove the (2) release screws from the lower half of the Limit Switch Cone Assembly.
3.) Install the mounting plate using ½” hardware. Attach to structural channel or a solid mounting surface. Be sure the plate is level front-to-back and side-to-side.
4.) Add a plumb bob to the mounting plate at the indicator hole and hang the bob down to ceiling. This is the center point for the hole cutout location for the microphone assembly.
5.) Cut a 1.75” hole in the ceiling aligned with the plumb bob.
6.) Remove the (2) Release Screws of the lower Limit Switch Cone Assembly. Slide off over microphone cable / weight.
7.) Raise the lift to the mounting plate – insert the lugs into the key holes and slide to narrow side of key hole slot.
8.) Install the locking screws on the side and rear of the unit
9.) Place the ceiling clamp over the drilled hole and thread the microphone cable / mic / weight through the clamp and through the ceiling hole. Slide the microphone cable / mic / weight through the lower Limit Switch Cone Assembly. Now slide the lower-Limit Switch Cone Assembly up through the ceiling hole and ceiling clamp. Tighten the clamp screw to hold in place.
10.) Reinstall the (2) release screws that attach the lower Limit Switch Cone Assembly to the upper portion.
11.) Adjust the ceiling clamp to “sandwich” the ceiling material – tighten the lock down Phillips-head screw.
12.) Replace ceiling bezel – install four screws.

Ceiling Microphone

A ceiling microphone may seem like a perfect idea when it comes to designing a room that needs a microphone, such as a conference room. It may even seem like the only place to put a microphone because is won’t clutter the room, it stays out of sight, and it won’t spoil the overall design of the room itself. But experienced engineers that specialize in audio say that a microphone like this is the last thing you want to add to a room.

The reason you might ask? Well, because it is too far away from the source you want the microphone to pick up. It is also usually too close to undesired noises such as loudspeakers, air conditioning vents, or even buzzing lights. A microphone is sensitive when it comes to noise. It can pick anything up including moving air. A microphone on the ceiling is no exception to this, and cannot determine which sounds are desired and which are not. It will pick them all up.

There are alternatives to using ceiling microphones which will work much better instead. For example, a television anchor uses a microphone on their lapel. You can easily find alternatives to a ceiling mic to place in a room. You can always place a small microphone in the middle of a conference table which will not stick out or become an eye sore. You can also use sets of lapel microphone which shouldn’t bother anyone in using them. If you must use a microphone connected to the ceiling, try using one with a stand that will let it reach down to ear level so you can obtain the best sound quality possible.

Five Executive HD Systems can be linked together to support up to 40 microphones in Maximum Density Mode, albeit without two-way audio. The HD System also has a reduced power mode which allows more Executive HD Systems to be used in a given area.
