Typical Ceiling Installation Arrangements:
Recommended ceiling installation arrangements for the EasyMic Ceiling MicPOD and ceiling speakers are
depicted in the above diagrams. Installation guidelines for ceiling applications include:
 Maintain a minimum ceiling microphone to ceiling speaker distance separation of 4’ (1.22m) for
optimum performance.
 Avoid placing ceiling microphone arrays next to HVAC systems, lighting ballasts, projectors and
any other devices that are noise generating sources. Remember that large amplitude noise
sources will be amplified by the microphones.
 Avoid hanging microphone heads in direct path of HVAC blowers within the room. Excessive air
flow over the microphone elements will reduce intelligibility of the audio.
The EasyMic Ceiling MicPOD was designed to allow the installer to adjust the hanging height of the microphone
element from the ceiling. A 36” drop cable is tethered to microphone array head and a strain relief clamp has
been incorporated into the interface module. This allows the hanging length of the ceiling array to be variable
with excess cable being secured with the strain relief clamp. For optimum performance, the microphone array
should be as close to the participants as possible. However, a minimum hanging height of 12” away from the
ceiling should be maintained.
