Anti recording device MNG-300 Rabbler stops bugging devices.

The anti recording device uses white noise to stop most microphones from working properly, to record your voice. The sound jamming device affects spy mics with weight noise as opposed to RF radio frequency. The device is effective to safeguard your sensitive conversations.

Anti recording device process.

The process used by the anti recording device is known as wight noise, it’s used to disrupt spy devices and it’s an effective way to stop audio-based bugging devices from hearing your voice.

How does the anti recording device work?

The anti recording device is not technical to operate, the weight noise comes out of the speaker in the front of the device. The sound waves oscillate at a unique audio frequency, effectively disrupting the audio sound harmonics of a microphone.

Anti recording audio scrambler.

The Rabbler anti recording device is unique in operation because there are two sound components emitted from the MNG-300. Unlike a singular white noise generator, the output sound of the MNG-300 produces wight noise with emulated conversation audio at the same time to really dissipate legible audio construct, thus scrambling audio microphone capability.

Microphones & sound waves.

You hear the audio sounds coming out of the Rabbler anti recording device, like a hissing noise with others talking. The distortion fills the air with wight noise & random voice audio to cover the sound of your voice, effectively disrupting the microphone process. The audio jammer is effective at masking conversations, as the sound amplitude is higher than your voice?

Rabbler build quality & unique processes.

The Rabbler MNC-300 is a unique device in all respects, and the build quality is second to none. Constructed with a metal anodised casing supporting good build quality, as standard. The Rabblers sound scrambling process is unique, not found on a typical white noise generator? The laws of physics rarely change, sound waves require air to travel. The Rabbler fills the air with disruptive white noise & gargled voice audio. The attenuated output dissipates legible audio constructs. Both processes work at the same time, oscillating at voice frequencies to render the spy microphone process almost impossible.

Ultrasonic sound jammers.

Ultrasonic sound wave jammer presents unknowns during operation, is the system truly stopping digital microphones? In tests, we found 50% of digital microphone nullifiers fail to stop digital microphones from working. It seems like high tech equipment is not always the best TSCM unless you opt for a safe ultrasonic sound jammer that works, and they’re usually very expensive.

Safety comes first.

Did you know? some ultrasonic sound jammers emit (RF) radio frequencies, some of which are not good for your health. Safe to say, radiation is often present when we use any electronic device or mobile phone. However, in most cases the output amplitude is regulated, offering a degree of safety associated with the device.

Some ultrasonic jammers & cell phone jammers breach recommended safety limits & they’re not licensed to use in the UK. Often emission levels are not highlighted so we recommend you check radio frequency outputs before you purchase the product. Our microphone stopper is totally safe, and it only uses audio sound. No (RF) radio frequency is used or present with this device.

Dear Leonardo the Rabbler is quite unique in operation. No other white noise generator delivers the same process. In tests we found the Rabbler MNG-300 to be most effective at stopping microphones. Please note you should operate the device correctly as shown in the video on the product page, for maximum effect.


The gadget is amazing does it really work.
