Device blocks any microphones, dictaphones (including professional ones) in the range of 7 meters (23 ft) and at even greater range when using the external ultrasonic speaker. For a maximal efficiency of ultrasonic interference it is advised to engage "TURBO mode". Acoustic interference volume can be adjusted (and even turned off for a completely silent operation), power can be supplied through a 220V power source or built-in battery."BugHunter DAudio bda-3 Voices" is a highly effective microphone jammerDid you hear about the powerful Russian microphone jammer "BugHunter DAudio bda-2 Voices"? There is an improved version available that provides an even more effective defense — "BugHunter DAudio bda-3 Voices"! New model retains all of the advantages of its predecessor, interference system got improved, two additional ultrasonic transducers and a jack for an external ultrasonic speaker were added."BugHunter DAudio bda-3 Voices" blocks any microphones in the range of 7 metersKey differences from the old model:New jamming system. "BugHunter DAudio bda-3 Voices" has a new ultrasonic pattern that guarantees even more reliable jamming of spying equipment in its range.Two vertical ultrasonic transducers create a "virtual wall" In addition to 5 transducers on BDA-2, the new model has two additional transducers located on the top panel of the device. Emitting interference in a vertical direction these two transducers create a "virtual wall" that protects you from any microphones or dictaphones located behind it.Device is equipped with seven ultrasonic transducers. Two are located on the top and five on the sideAbility to connect an additional ultrasonic speaker. In comparison to "BugHunter 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. Working with an additional speaker "BugHunter 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.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 (shown in the photo below).This simple adapter lets you connect two ultrasonic speakers to the jammerOther advantages of "BugHunter DAudio bda-3 Voices":Acoustic speech-like interference guarantees 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 guarantee trouble-free use of the jammer! "BugHunter 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. "BugHunter DAudio bda-3 Voices" will jam any "bug" and won't let anybody learn your secrets.UNIQUE! Incredibly high suppression power and range! "BugHunter DAudio bda-3 Voices" emits a 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.Capability to connect one or two additional ultrasonic speakers makes "BugHunter DAudio bda-3 Voices" even more effective in protecting oneself from audio espionage (Attention! Package doesn't include the additional speaker. It is sold separately)Operating principleDevice 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.Flexible volume adjustmentAcoustic speech-like interference guarantees 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 "BugHunter 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 jammer 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.Using the jammerAnybody, 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.Setting up the ultrasound speaker under the table you will make the jammer even more effectiveUse the jammer stationarily or portably"BugHunter 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.Four-level battery charge indication systemTo avoid missing the moment when the battery loses charge device has a charge indication system.

By paying a little extra, you will be able to protect your meeting room from spyware more reliably. By itself the jammer offers protection directly in front of you and additional speakers generate interference from other sides. In this case ultrasonic interference becomes denser and more effective at jamming spyware.It is better to place external speakers in a way so that ultrasonic interference would cover all possible locations of spyware.Using additional ultrasonic speakers is more economical in cost than using two or three "BugHunter DAudio bda-3 Voices" jammers and a lot more efficient than buying expensive jammers with a large number of transducers pointed in one direction. You need to consider that with every meter distance, power of ultrasonic interference decreases by 2-3 times, that's why bulky analogues with "50 unidirectional transducers" won't create the result you expect. All these are not allegations but facts verified by experiments.How to correctly place ultrasonic speakers.Depending on the size of your room and location of people you are talking to, you might require one or two additional ultrasonic speakers. We suggest only some of the possible layouts on the base of which you can determine what places work best in your case.If you have only one speaker place it under the table…Or point the side with transducers towards the other person while the jammer itself will be lying on the table in front of you.When using two speakers, usually one speaker is placed under the table and other one is placed on the wall or shelf.To connect 2 speakers to a single device, purchase this cheap splitter for 2 mini-jacks 3,5 mmSpecifications:Connection typemini-jack 3,5 mmOverall dimensions95х55х23 mm (3,7x2,1x0,9 inches)Weight (without adapter)80 gr (2.8 oz)External source of power supply12 VPower consumptionUp to 0,25 АSound pressure level (at 1 m distance from the device), dBNot less than 120Package contents:additional ultrasonic speaker for "BugHunter DAudio bda-3 Voices" microphone jammer;power adapter for 110/220V power supply;individual packaging.English User Manual...
