The development of directional microphones has been part of the PKI business for more than 40 years. The challenge is enormous, the demand immense. As a result of the progressive electronics development, engineers think to have reached the limit, but they are taught a lesson by new components. The result is this PKI 2950 Audio Horn Type Directional Microphone with Remote Transmission.
PKI 2950 is the result of our latest development. A commercially available laptop bag is used as camouflage for the elaborate and complex technology. The PKI 2950 Audio Horn Type Directional Microphone with Remote Transmission consists of a horn type directional microphone with downstream amplifier with an 80,000-fold amplification factor and a 7-band equalizer.
Listening-in is directly possible via a headset or wirelessly via the built-in 1W HF transmitter up to a distance of 200m. A recording possibility is given in the device itself or integrated into the HF receiver. The application of PKI 2950 is absolutely straightforward. Switch on the different devices, align the bag and execute the control function via the delivered headset, then position yourself with the camouflaged HF pocket receiver in a radius of 200m and record or monitor the desired conversation.
