Key features of "BugHunter DAudio BDA-2 Ultrasonic":
1) Absolutely silent operation. The device can be used discreetly because it emits ultrasound inaudibly for people. Ultrasonic interference is efficient for suppressing almost all types of eavesdropping devices.

2) Unique suppression system. The device generates ultrasonic interference which is designed to suppress even the newest waterproof smartphones with noise cancellation. The interference is spread not only in front of the transducers, but also sidewise, which allows to suppress microphones and smartphones located at an angle from the device.

Operating principle
The device emits ultrasound through 5 built-in transducers. The ultrasonic frequency changes in accordance with a specially developed algorithm for maximum suppression. These unique ultrasonic waves affect the recordings of eavesdropping devices (voice recorders, microphones of cell phones, etc.), so that they record only indistinct noise, making it impossible to distinguish any details of the conversation.

Option to connect additional ultrasonic speakers. External speakers can be connected to the device to create speech-like interference for extra protection. Therefore, eavesdropping devices record only unintelligible mumbling which is impossible to understand. Speech-like interference is generated randomly, so you can not filter it even with the help of special equipment.

This complex protection ensures the highest possible level of confidentiality. At the same time, the device operates silently as ultrasonic signals are not perceived by the human ear and the volume of the speech-like interference can be easily adjusted.

Competitive advantages of microphone and dictaphone suppressor "BugHunter DAudio BDA-2 Ultrasonic":
1) Guaranteed protection. The device suppresses most of the spy devices with microphones.
The device is designed for portable and hidden use. It is able to suppress all types of microphones (smartphones, professional voice recorders like Soroka, Gnom, Edic, etc.) located in the device’s action range.

2) High suppression power and action range.
The device’s transducers emit powerful ultrasonic waves (not less than 120 dB) which suppress microphones at a distance of up to 7 m (23 ft).
Do not bring the transducers close to your hearing organs in order to avoid injury

3) Transducers are located on the side of the suppressor.
The jammer generates both directed waves of ultrasound and a scattered wave that spreads to the sides of transducers. It means that ultrasonic interference will affect smartphones or voice recorders at a larger range enhancing the effectiveness.

4) Option to connect external acoustic speakers to protect larger rooms.
Speech-like interference can be added by connecting external speakers (such as a computer speaker system) via the jack located on the front panel of the device. Speech-like interference is capable of suppressing directed laser microphones and provides a wider operation range, so it can be used even in large premises.

6) Portable and stationary use.
Microphone, dictaphone suppressor "BugHunter DAudio BDA-2 Ultrasonic" operates from two power sources: 110/220 V electrical mains and a built-in battery with capacity of 2500 mAh. The operation time on a single charge is about 2-3 hours.

How to use
The device is simple to use and requires no pre-setting. Point the transducers to a place of possible eavesdropping devices and turn it on by pressing the button located on the front panel of the device. "BugHunter DAudio BDA-2 Ultrasonic" starts operating immediately, protecting you from any eavesdropping.

Keep in mind that using several jammers and directing them to eavesdropping devices from different sides is more efficient. For instance, ultrasonic interference of one device cannot be enough to suppress recording on waterproof smartphones (iPhone 8+, Samsung Galaxy S10, etc.). In this case, using two or more devices at the same time is the best solution.

For maximum protection you can use two or more suppressors
Before using the suppressor we recommend to:
1. Check the battery level if the device is operating portably.
2. Test the device before using. You can use the voice recorder on your cell phone for the test. Turn the jammer on, point the transducers at the cell phone, talk from the other side of the device making sure that the jammer is always between the talking person and the recording device. Then listen to the record. If you hear unintelligible noise on the recording, the device operates properly.
