Super Digital Directional Microphone

PKI 2935Print

Outdoor audio monitoring has always been a predominant topic for PKI (refer to the PKI 2975 investigation kit for outdoor use) With this new PKI design, we outperform conventional directional microphones. The PKI 2935 is the most sophisticated directional microphone of its type anywhere in the world. We camouflaged the entire technology in a laptop bag because it is permeable to acoustic noise. More than 100 microphones record the received acoustic signal and digitally process it to the directional characteristics. Low-noise amplifiers and filters do their best to obtain an interference-free, low-noise signal. The effect is stunning. In case of interest, we are readily prepared to send you a demo recording. The received signals are simultaneously recorded for further processing. In addition, direct wireless listening is possible with the delivered laptop. PKI develops practice-oriented devices for professional applications. The result is all that counts and this is absolutely true here. The PKI 2935 opens up a new field of remote acoustic monitoring. It helps to make conversations audible over long distances even under the most difficult conditions. The alignment of the PKI 2935 takes only a few seconds. This way, the user immediately obtains exploitable information even in critical situations.
