Product Description
Upgraded version of “DAudio BDA-3 Voices” microphone suppressor equipped with
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 in 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 the operating positions: either ultrasound or ultrasound + white noise. After that, you can control the device by turning the interference signal on and off at your own discretion.
Key differences from the old model:
The 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. Compared tBDADAudio bda-2 Voices,” which supported only acoustic speakers to amplify the acoustic interference, the new model keeps the connection of ultrasonic speakers via a mini-jack cable. When operated with an additional speaker, “DAudio bda-3 Voices” efficiently suppresses even hidden microphones located outside the range of seven primary transducers. For maximum efficiency, another 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)
Necessary: 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 potent 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 of your safety! Upgraded hardware. Ultramodern elements base gives you the highest possible power of microphone suppression. Besides, high-quality hardware increases the device’s reliability and extends its operating time. We can assure trouble-free use of the suppAudi! “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 due to 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 (Soroka, Gnom, E-disc, etc.), directional microphones, cellular telephones, 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 potent ultrasonic and acoustic signals (up to 120 dB). It can jam microphones at a distance of up to 7 m (23ft). Most analogs, especially Chinese production, are at least 2-3 times weaker, even by the declared characteristics. Emission power is so high that our specialists recommend keeping 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 generator that emits a slightly different frequency ultrasound. 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 a human can hear overlapping signals. 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.
Connect speakers to cover larger rooms and/or suppress directional microphones. You can output acoustic interference to external speakers via an audio jack located on the front side panel of the device. It will let you protect even huge rooms from eavesdropping. Besides, the external speaker makes directional microphones useless.
Operating principle
The device generates an ultrasonic signal through 7 transducers. Frequency is determined by a micro-controller and variates according to a specially developed algorithm. Ultrasonic signal affects spyware’s recording paths, resulting in them fixating only indiscriminate noise in which conversation can’t be distinguished.
Besides, the 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 maybe a nuisance in a conversation. Our developers took this into account and developed “DAudio bda-3 Voices” to adjust the volume of BDA acoustic interference. You can constantly change the book so that the device won’t muffle your speech and you can speak comfortably. If the 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, the suppressor will be working entirely 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 the 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 minor inconvenience.
Anybody, even a non-professional, can use the jammer. All you need to do is point the transducers toward 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 additional ultrasonic speakers.
“DAudio bda-3 Voices” can be powered by a power supply or 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, the jammer will always be with you, ready to protect you from spying. And you can charge it and use it 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 average; flashes once per second — device works but battery needs charging; flashes 2 times per second — intense battery discharge, the device doesn’t work; not lit — battery is completely discharged.
