Discreet and at the same time very effective speech protector. The design of the EO-3 MAX does not interfere with the meeting as it looks like a classic speaker. However, it effectively protects you from leaking information. It combines ultrasonic and acoustic noise – protecting up to a range of 7-50 metres. Now your conversation stays private.

  • • Ultrasonic noise effectively protects against eavesdropping, but at the same time does not interfere with the meeting, it is completely discreet.

  • • Ultrasonic noise reliably overwhelms microphones at a range of up to 7 meters, protecting you from eavesdropping and bugs.

  • • Acoustic noise generator can effectively disrupt your conversation. An attacker will not be able to make a quality recording using a stethoscope or laser eavesdropping device..

  • • The speech protector can generate your own voice as acoustic noise..

  • • You can set the intensities and modes of wiretapping.

  • • It is completely discreet and looks like a classic speaker.

A really discreet EO-3 MAX speech protector in the form of a large speaker. Thanks to this masking, no one will suspect that it is a wiretapping device and your meetings will go on completely undisturbed. The EO-3 MAX speech protector protects up to a distance of 7-50 meters, i.e. the furthest of our speech protectors. Combines ultrasonic noise that overwhelms nearby bugging microphones along with acoustic noise. This combination brings the state-of-the-art and best possible eavesdropping protection. Another advantage is that you can record your own voice into the acoustic noise, which the speech protector will then generate to drown out your conversation.


  • Digital and analogue voice recorders
  • Dictaphones in mobile phones
  • Remote laser eavesdropping through windows
  • Built-in and directional microphones

EO-3

Parameters

Functions of Ultrasound

It protects against eavesdropping through the wall with astethoscope microphone, and even prevents eavesdropping through window panes with a laser microphone. Acoustic noise provides an additional level of protection against eavesdropping based on technology other than conventional microphones. It protects, for example, against a third party who would like to eavesdrop on you from afar. Acoustic noise generates different voices, which you can also record into the speech protector. These then

Easy to Use

Our EO-3 MAX discreet jammer is easy to use. Just place it where you expect eavesdropping. Remember that the effective distance at which the jammer will protect your conversation is a maximum of 7 metres when using ultrasound, and up to 50 metres for acoustic noise. You don’t need to configure anything complicated. Simply plug the jammer into electricity and operate it with a few buttons or a remote control.

Acoustic noise

Acoustic noise protects especially against laser and stethoscope microphone. Acoustic noise thus easily protects you from eavesdropping through a window pane, through a wall, or by a third person from a distance. In contrast to ultrasonic noise, acoustic noise is audible to the normal ear. It works by overlaying your conversation by randomly generating words. You can even record your own voice nto the speech protector as an acoustic noise.

Instructions For Use

Place the EO-3 MAX discreet speech protector where you expect to eavesdrop on a potential meeting participant. Simply plug the device into electricity and then you can turn on the ultrasonic noise, as well as switch between different modes. The speech protector looks like an ordinary speaker, it is advisable to place it, for example, in the corner of the room – with a range of up to 7 meters, it will reliably protect you from information leakage through eavesdropping.

A: Silent ultrasound –suppresses high quality voice recorders

B: Device off – protection is switched off

C: Ultrasound and quiet acoustic noise is the main operating mode that allows you to act comfortably and protects you against all types of eavesdropping devices

If you need to record your own voices into the EO-3 MAX to generate acoustic noise, press and hold the volume button (also the on/off button) on the back of the speaker for 5 seconds. The LED above the button will then flash. While the LED is flashing, speak any text for at least 5 minutes. Then press the volume button again and the recording will stop, the LED will stop flashing. You are now ready for use.

Important

When using an ultrasonic generator to drown out microphones in the vicinity, certain limitations arise from the laws of physics. Some microphone designs are more susceptible to jamming than others – so the effectiveness can vary by microphone type. The maximum effective range of a generator can therefore vary by a factor of several times depending on this. In addition, the generated ultrasound bounces off surfaces and is unable to penetrate most materials to any great depth. For this reason, it is recommended to use a sufficient number of devices and then to position them appropriately in the room to best ensure privacy during meetings and appointments.

For the highest possible quality of interference, Acoustic Noise feature allows you to record your own voice and overlay it on your conversation. The recorded voice is then randomly generated, creating a sound barrier against eavesdropping by a stethoscopic microphone or laser eavesdropper. In addition, it also protects against state-of-the-art forensic voice cleaning methods.

Although the device does not guarantee 100% jamming efficiency, it is superior to competing solutions. Due to its configuration, it guarantees high effectiveness when confronted with microphones on devices such as dictaphones, eavesdroppers and seismic microphones, microphones on computers, headsets, cameras and mobile phones.
