NAR Safety Grant - PA system:


From the Grant Application:

Grant Type – Range operations equipment.

Safety problem – We need a PA system that can be heard all over our field to provide rocket launch announcements, safety warnings, and crowd control. Our current PA system is not sufficient enough to provide loud enough audio announcements/warnings beyond a small distance. 

                We have a field at a Naval Auxiliary Airbase in Chesapeake, VA. For a PA system we only have a small one speaker system that is not loud enough or omnidirectional to adequately cover this field. When we have a large event we rent a PA system that is very costly and it would quickly drain all our funds if we had to rent it on a regular basis. I have been to several other Clubs and most of them do not have omnidirectional speakers. The speakers are usually facing the launch audience but you cannot hear the announcer if you are out on the field. This proposed PA system will have dual four speakers systems that will face all four directions and have a strong amplifier.  

                For this Grant we would purchase a complete outdoor PA system that would have sufficient power and be omnidirectional. The system would also have wireless microphones for other officers to make any safety alerts while out in the field. We have saved up Club funds and will receive additional donations to cover the additional amount beyond the Grant limit.

Speakers:

PA type speakers, 70V or 8 ohms

Nice stands for $30/each.

Assemblying the speaker holder plates. Plates can support two or four speakers. Stainless steel fasteners were used. Will convert the wood plates to an outdoor material in the future.

Two speaker stands, four speakers, to radiate out to a large field
