ULTRAVOX-TC/24-180
Short description
ULTRAVOX-TC/24-180 (“tube”) is a professional device for protecting conversations from recording on voice recorders, smartphones and hidden microphones, made in a “tube” form factor. The design with two-way ultrasonic interference direction provides effective suppression of recording in two directions simultaneously, significantly increasing the protection area. The device is ideal for conference tables where protection of all participants on both sides of the conversation is required.

Purpose
ULTRAVOX-TC24/180 belongs to the class of stationary devices for protecting negotiations from recording by voice recorders, smartphones and hidden microphones.
The distinctive feature of the model is its dual-direction ultrasonic interference design, which effectively suppresses recording simultaneously in two directions, significantly increasing the protection zone.
ULTRAVOX-TC24/180 supports installation both on and under a table, providing flexible integration into the interior of a meeting room. Silent operation mode and camouflaged design allow the device to be used without drawing unnecessary attention.
The device effectively counteracts unauthorized recording using:
- mobile, stationary and radio-frequency recording devices
- professional audio recording equipment
- hidden and external microphones
- mobile phones
Operating Principle
Ultrasonic Interference Generation
The device generates a complex signal in the ultrasonic range that is not perceived by the human ear.
24 ultrasonic emitters generate noise interference in two directions.
Effect on Microphones
The interference distorts the signal reaching the microphones, making voice recording unintelligible or completely impossible.
Limitations
Ultrasound does not pass through solid obstacles (walls, furniture, partitions), so for effective protection the device should be placed within the protected area.
