PARABOLIC MICROPHONE FOR INVESTIGATIVE USE
The parabolic microphone involves a highly reflective parabolic dish, an omnidirectional microphone, a preamplifier and a headphones for real time listening, in addition you can connect to it a voice recorder to record intercepted conversations.
Sound waves picked up by the parabolic microphone properly oriented, hit your dish and are conveyed into the rear center where the audio is concentrated and directed into the omnidirectional microphone. In this way, the audio signals received, are amplified compared with the result that you would have with a normal directional microphone. This element not only amplifies sounds, but "select" signals, eliminating unwanted noises, coming from other directions. So the parabolic dish isolates the sound carried by perpendicular waves to the direction getting professional results.
Our Eagle parabolic mic is designed specifically for investigative and tactic operations, it intercepts eviromental conversations from as little as 3 feet or as much as 500 feet, but it lends itself to be used in television, film and sports. The audio quality depending on weather conditions, but the hight quality electronic system, ensures perfect results.absolutely flawless.
Eagle parabolic mic has hand held or tripod mounted, it has two comfortable grips on either side of the dish making it easy to hand hold and aim. The bottom of the unit has a mounting plate with 1/4" threads for mating to a tripod for fixed or aimed shots.
Audio can be picked up from as little as 3 feet or as much as 500 feet depending on wind and weather conditions.
