Despite its small size, SEL-310 "Komar" is a high-power and efficient microphone jamming device due to its thought-out design, that includes high-quality directional ultrasonic transducer array that pushes a complex, tailor-made noise waveform on a frequency band that is below human hearing point, but right in the zone of common audio microphone bandwidth, applying a constant noise pressure on the microphone’s membrane.
Distinctive features: An array of 10 high-quality piezoelectric transducers, controlled by a microchip that automatically shifts the noise signal in time and frequency domains, achieving best possible jamming efficiency and rendering any actual speech signal on the microphone unintelligible. Flexible power supply: device can draw power either from the 220 V mains, from a car 12 V onboard power supply socket, or from a built-in Li-Pol battery. Easy to use control: can be turned on/off via a button switch on the device, or wirelessly with a special RF remote control. Indicator dashboard: device constantly gathers self-diagnostic and battery charge data and outputs it to an easy-to read LED indicator dashboard on the back panel of the device. Long battery life: not less than 5 hours of constant operation on full charge.
