All-round ultrasonic jammer SEL-360

SEL-360 is a high-power and efficient microphone jamming device due to it's 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.

Ultrasonic transducers in the SEL-360 suppressor are installed in a circular array, providing reliable jamming in all directions around the device, which makes it a perfect choice for securing meeting tables and desks.

Features:

• An array of 48 high-quality piezo-ceramic transducers, installed in a circular shape inside a drum-like unit, 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 220V mains or from a built-in Li-Pol battery, with capacity enough for 3 hours of continuous operation.
• 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 bottom panel of the device.
