Audio transmission without loop

Clear communication is an important success factor for security agents. This is why audio transmission systems for mobile surveillance, for example in covert applications, are now at a high-tech level.
Phonak Communications is now making a contribution to this with Roger Covert.
For the first time, the system enables loop-free operation, which offers the wearer more flexibility. 

Thanks to the latest microphone technology, messages can be heard even in noisy environments or in whisper mode. With its ergonomically designed, virtually invisible earphones,12 hour battery life and a range of configuration options, Roger Covert offers security experts a highly adaptable system.
Phonak CEO Evert Dijkstra: "The system does not need any induction loops, so that security forces can have a wider choice of clothing, move more freely and so are less restricted in difficult situations. Combined with a highly sensitive microphone and excellent audio transmission, we have developed the most powerful, flexible and secure system on the market today.
It is based on Phonak's "Roger" technology with AES 128-bit encryption. The technology uses a combination of state-of-the-art audio processing technology, adaptive, "frequency hopping" and other features for high quality audio performance and speech intelligibility.
The miniature components used for this purpose enable the use of extremely discrete audio receivers.
