Super Directional Microphone

Product number: PKI 2930

Would you like to „hear the grass grow“? With this PKI 2930 super directional microphone you will almost be able to do so! The built-in electret directional microphone captures acoustic signals from up to 100m distance, which are amplified up to max. 10.000 times by its powerful low-noise amplifier and can be heard via head- or earphones. Due to the integrated high- and lowpass filters you can even listen to conversations at a distance of 50m, as they allow especially voice frequencies to pass through and eliminate undesirable noises. It is incredible, that this is possible, particularly in this inconspicuous and small design. Conversations can be listened to directly or recorded on our digital miniature recorder, i.e. both units work fully automatically without your presence. If required you can listen to all conversations at any time later on!
