The Stealth SM2040DX

Portable Audio Jammer and Speech Protection System

The Stealth SM2040DX is the most advanced portable audio jammer and speech protection system which protects you against third person listening, eavesdropping, and recording devices. The Stealth SM2040DXcreates sound barrier interference which masks your speech and conversation to be extremely difficult or impossible to extract the original content from the noise.

When it is used in the correct manner, The Stealth SM2040DX will protect you from;

• Third person listening
• Voice recorders(tape and digital)
• Microphones, wireless microphones
• Stethoscopes, laser listening device
• GSM/Bluetooth/Wi-Fi transmitters, etc.

Main Functions

1. Sound Masking (Audio Jamming)

The 2 channel chaotic noise (Distortion + Reverberation) in a random sequence secures your privacy and information from recent hi-tech speech extraction software.

• Main Speakers: 500 mW x 2(Top & Bottom) – adjustable output level

The built-in 2 speakers create sound barrier interference against listening and recording nearby its location. – Indoor interference

• Sub-Transducer: 500 mW x 2 – adjustable output level

These 2 special transducers (TRN600S) can be installed on window, wall, partition, ceiling and hard floor toemit the chaotic noise with random vibration depending on the output of noise to protect your speech and conversation from eavesdropping and third party listening. – Outdoor interference

• External Output

The Stealth SM2040DX provides a 3.5 mm standard external output jack for an external speaker (Omni-Speaker) or amplifier for extra sound barrier, if necessary.

1. 4 Channel Communication Ports

The Stealth SM2040DX has 4 built-in channel communication ports to provide high quality secured communication for protecting speech between up to 4 people.

• Each communication port can be controlled its output level to optimize for each user
• The users between its communication ports won’t be disturbed by the interference of chaotic noise.

Features

• Protects against all known methods of listening and recording devices - All types of radio microphones, stethoscopes, voice recorders, passive resonators and wired microphones, etc.
• Voice Activated output for efficient and comfortable usage – The output audio interference level is beinggenerated simultaneously with the input human’s speech. The volume of this interference is higher than a person’s voice; therefore neither a listening device nor a recorder is able to pick it up.
• Compact Portable Design – it can be easily carried and prepared for instant usage.
• Easy to use – No professional installation and skills are required
• Provides a much higher level of protection than any white-noise generator in the market.
• It can be used in any situation. – Office, Home, Meeting Room, Car, Hotel
• The transducers and external output give additional protections against any recording and eavesdropping activities – Triple protection
• Each noise output and communication channel can be adjusted individually for best result.
• Absolutely harmless – no microwave reflections or ultrahigh sound noise.
