ULTRAS-T. Ultrathin Ultrasonic Suppressor of Voice Recorders and Microphones
Designed for installation in hard-to-reach places under the surface of the negotiating table, in the car, etc.
ULTRAS-T is a powerful and effective device for suppressing microphones in voice recorders, mobile phones and other means of audio recording by emitting complex structured interference in the ultrasonic range, inaudible to the human ear, but acting directly on the microphone membrane with its sound pressure.
Advantages and features
Structurally, the suppressor of voice recorders and microphones ULTRAS-T is made in the form of a half circle (sector) with a thickness of only 25 mm with 24 piezo ceramic emitters located around the perimeter of the sector, which allows it to be installed under the tabletop of the conference table or in a niche under the car dashboard.
In the ULTRAS-T suppressor, ultrasonic interference extends 180 degrees.
For ease of installation, a magnetic mount is provided (optional).
The universal power supply system allows the ULTRAS-T suppressor to operate from a 220 V network, from the vehicle's on-board network or autonomously up to 3 hours from an internal battery.
In addition to manual “push-button” switching, the ULTRAS-T suppressor has a wireless remote control system using a key fob.
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, ensuring high reliability of the product and the convenience of its operation.
The suppression range depends on the type of microphone, recorder or mobile phone and its location relative to the suppressor of recorders and ULTRAS-T microphones. In practice, most voice recorders and microphones of mobile phones are effectively suppressed at a distance of up to 2 m. But there are separate models for which this distance does not exceed 0.5 meters, and microphones of some electronic devices are well suppressed at distances up to 10 m
