MSK – Microphone Suppression Kit – Muti-Directional Ultra Sonic Suppressor – Microphone Defeater
Multi Directional Microphone Suppression Kit, Protect Confidential discussions using Covert or Overt Microphone blocking technology.
- Prevent unauthorized audio recordings in meeting rooms and offices.
- Built to Protect confidential discussions from unauthorized recording devices.
- 2 Ultrasonic Speakers for multi directional protection.
- Two technologies onboard, ultra-sonic emission (silent) & White Noise Acoustic Interference
- Protect Discussion areas by strategically deploying MISK towards threats.
- Can be used Covertly or Overtly
- Remote Control Operation
The Microphone Suppression Kit (MSK) is able to neutralize microphones, hidden voice recorders, and audio transmitters, protecting discussions from unauthorized recording devices.
MSK uses silent ultrasonic waves and can overpower all of the microphones within its action range.
This device covers up to 10-11 feet of area, areas such as offices or meeting rooms, with the use of the main unit plus the additional ultrasonic mini speaker (supplied).
The small form factor of the primary suppressor means users can easily transport the device and use it in the field thanks to the integrated rechargeable battery which can perform for up to 5 hours, protecting an area of about 8 feet when using the primary suppressor on its own.
The Microphone Suppression Kit generates a virtual barrier between the subject and the potential eavesdropping threat, ensuring that confidential communications cannot be secretly recorded.
In addition to the ultrasonic transducers, the central unit has a loudspeaker with separate volume to generate, if necessary and if desired, an audible audio noise similar to white noise.
(Please note that using this additional White Noise feature is not recommended for covert requirements.)
Using the MSK
The device must be positioned with the transducers facing the possible position of the interception devices (environmental recorders, hidden microphones, audio bug transmitters, etc.). For example, towards new guests, which represent non-neutralizable threats where audio recorders on cell phones, tablets, or other devices may be secreted into a confidential meeting.
The primary device must be positioned directly towards the target at a distance of less than 8 feet away.
In most cases, a meeting between 2 parties will be much closer than 8ft.
The optimal maximum distance between the transducers and the interceptor microphone is 10 feet, with the additional mini ultrasonic speaker being used towards the threat from a different angle, creating a stronger virtual wall of ultra-sonic suppression.
