The remote control for BDA-3 has an action range of 10 m (33 ft). You can switch the ultrasonic interference on and off while sitting in your chair. This comfortable way you can inconspicuously protect yourself from eavesdropping (if you engage only ultrasonic mode).

The remote control is capable of controlling the whole BDA-3 suppression system:

microphone and dictaphone suppressor BDA-3;additional ultrasonic speakers (up to 4 pieces can be used simultaneously);acoustic speakers for white noise amplification.

You need to switch the suppressor to “standby” mode by moving a rotary knob to one of operating positions: either ultrasound or ultrasound + white noise. After that you can control your the device by turning interference signal on and off at your own discretion.

Key differences from the old model:

BDA-3BDA-3

Device is equipped with seven ultrasonic transducers. Two are located on the top and five on the side

Ability to connect an additional ultrasonic speaker. In comparison to “DAudio bda-2 Voices” that supported only acoustic speakers to amplify the acoustic interference, the new model supports connection of ultrasonic speakers via mini-jack cable. When operated with an additional speaker “DAudio bda-3 Voices” efficiently suppresses even hidden microphones, which are located outside the range of seven main transducers. For maximum efficiency additional speaker can be placed on the side of the speaking person (so that transducers are pointed at him from different directions) or under the table.

Other advantages of “DAudio bda-3 Voices”:

Example of combined usage of a jammer with two speakers (one speaker is located on the wall and the other one is under the table)

Important: Ultrasonic speaker is not supplied with the jammer and is sold separately. If needed, you can attach two speakers via a regular splitter for a 3,5 mm jack.

Acoustic speech-like interference ensures 100% confidentiality. In addition to ultrasound, the new model has a powerful speech-like interference that generates randomly and makes eavesdropping completely impossible. You can’t filter out such interference even on the modern equipment, so no matter what adversaries do they will only record meaningless noise instead of your conversation. You can be 100% sure in your safety!Upgraded hardware. Ultramodern elements base gives you the highest possible power of microphone suppression. Besides, high quality hardware increases reliability of device and extends its operating time. We can assure trouble-free use of the suppressor! “DAudio bda-3 Voices” will protect you for a long time without breaking which is not the case for many other devices.100% PROTECTION — not a single spyware with a microphone will be able to “eavesdrop” on your conversation. This reliable protection is possible as a result of using two efficient technologies at the same time: ultrasonic signal + speech-like interference. Any equipment becomes equally useless: laser, wired and wireless microphones, professional dictaphones (such as Soroka, Gnom, E-dic etc.), directional microphones, cellular telephones and etc. “DAudio bda-3 Voices” will jam any “bug” and won’t let anybody learn your secrets.UNIQUE! Incredibly high suppression power and range! “DAudio bda-3 Voices” emits very powerful ultrasonic and acoustic signals (up to 120 dB). It can jam microphones at a distance up to 7 m (23ft). Most analogues, especially of Chinese production, are at least 2-3 times weaker even going by the declared characteristics. Emission power is so high that our specialists recommend to keep transducers away from hearing organs to avoid injury.NEW! TURBO mode for even more effective suppression when you need absolute confidentiality. TURBO mode activates a special generator which emits ultrasound of a slightly different frequency. Interaction of ultrasonic signals of different frequencies creates frequency beats which raise suppression efficiency without raising emission power. It is a unique development of our specialists! You will not find a similar function in other devices. If you need maximum possible protection against spyware, use acoustic interference together with the TURBO mode and do not worry about anything.

Note: The only inconvenience in using TURBO mode is that overlapping signals can be heard by a human. That means that when you are not using acoustic interference but TURBO mode is on, you will not be able to use the jammer absolutely secretly. But it will not prevent you from talking, you do not have to strain your voice to speak louder.

Ability to connect speakers to cover larger rooms and/or suppress directional microphones. You can output acoustic interference to external speakers via audio jack located on the front side panel of the device. It will let you protect even very large rooms from eavesdropping. Besides, external speaker makes directional microphones useless.

Operating principle

BDA-3 with speakerBDA-3 with speaker

Device generates ultrasonic signal through 7 transducers. Frequency is determined by a micro-controller and variates according to a specially developed algorithm. Ultrasonic signal affects recording paths of spyware which results in them fixating only indiscriminate noise in which conversation can’t be distinguished.

Besides, powerful speaker creates acoustic speech-like interference which destroys the meaning of the conversation: because of it spyware fixates only indiscriminate muttering, restoring the conversation becomes physically impossible. Acoustic interference is generated randomly so it can’t be filtered out even on special equipment.

Acoustic speech-like interference ensures the confidentiality of the conversation but has one flaw — unlike ultrasound it can be heard and my be a nuisance in a conversation. Our developers took this into account and developed “DAudio bda-3 Voices” with an ability to adjust the volume of the acoustic interference. You can always adjust the volume so that device won’t muffle your speech and you could speak comfortably. If suppressor is a nuisance, just turn the volume down. Turning the knob to a minimum you will turn the acoustic interference off.

If acoustic interference is turned off, suppressor will be working completely silently (except TURBO mode). One will not pay attention to the working device. If you hide it under the table, for example, there will be no clear evidence that suppressor is working.

But without the acoustic interference reliability of protection becomes lower. If you want to be 100% certain that ALL devices with microphones are suppressed, you will have to tolerate small inconvenience.

Anybody, even a non-professional can use the jammer. All you need to do is point the transducers in a direction of an expected location of recording devices and turn it on. You can adjust the volume level of the acoustic signal if needed. Notice that you can make your protection more reliable by using an additional ultrasonic speakers.

“DAudio bda-3 Voices” can be powered by power supply or by a built-in battery. Its charge will last for a few hours which is a good number for a device of this power. Wherever you go, jammer will always be with you ready to protect you from spying. And you can charge it and use stationarily when you get access to a power supply.

To avoid missing the moment when the battery loses charge device has a charge indication system. It is a green light on a front panel that has 4 modes:

constantly lit — charge is normal; flashes once per second — device works but battery needs charging; flashes 2 time per second — strong battery discharge, device doesn’t work; not lit — battery is completely discharged.

ULTRASONIC EXPOSURE + VOICE IMITATION = 100% microphone suppression
SOPHISTICATED ULTRASONIC PATTERN that is effective against newest noise-canceling and water-resistant phones. Range and effectiveness can be increased when used with one or more external ultrasonic speakers (sold separately).
CAN BE USED ABSOLUTELY SILENTLY but best results achieved when ultrasonic and white noise interferences are combined.
HIGH SUPPRESSION POWER AND ACTION RANGE. This microphone blocker emits a very powerful ultrasonic signal (not less than 120 dB) which suppresses microphones at a maximum distance of 7 m (23 ft). The distance is shortened to 2 m (7 ft) for newest iPhone models with an improved noise cancelling system.
7 ULTRASONIC TRANSDUCERS that ensure protection in front and across the device. Use it as a “virtual wall” to protect yourself from recording devices.
