ULTRAS-M. Dictaphone suppression system in the bag
Small-sized suppressor for recording dictaphones and microphones (including mobile phones) for individual use when talking outdoors, in the car or indoors. Can be easily placed in the car, on the table or installed in a specially prepared briefcase (handbag)
Despite its small size, ULTRAS-M is the most powerful and most effective in its class device for suppressing microphones in voice recorders, mobile phones and other audio recording means due to the directional radiation of complex structured interference in the ultrasonic band, inaudible to the human ear, but acting directly with its sound pressure on the microphone membrane.
Benefits and Features
In the ULTRAS-M suppressor, ten independent digital ultrasonic oscillation generators under the control of a microprocessor generate a complex noise-distributed time-varying frequency noise signal, which with the help of piezoceramic emitters creates a high-power ultrasonic barrier inaudible to the human ear, but well perceived by microphones, " suppressing ”while the useful speech signal.
The universal power supply system allows the ULTRAS-M suppressor to operate from a 220 V network, from the vehicle's on-board network, or independently from an internal battery.
In addition to manual “push-button” switching on, the ULTRAS-M suppressor has already installed a wireless control system using a radio remote control.
The microprocessor control system, automatic continuous self-diagnosis of the state of the battery and the operation of each ultrasonic channel maintain a constant highest level of ultrasonic interference power throughout the entire battery life (more than 5 hours), ensuring high reliability of the product and ease of use.

The suppression range depends on the type of microphone, voice recorder or mobile phone and its location relative to the ULTRAS-M.
In practice, most voice recorders and microphones of mobile phones are effectively suppressed at a distance of up to 2 meters. But there are separate models for which this distance does not exceed 0.5 m, and the microphones of some electronic devices are well suppressed at distances up to 10 m.
