VSB Earphone Inductors and Accessories

The VSB System uses a novel, specialised audio signal modulation method which has been specifically developed to provide optimum performance in conjunction with the advanced digital signal processing implemented in the VSB Digital Wireless Receiver.  The patent-pending method used in the VSB transmitter/receiver combination delivers drastically reduced levels of audible interference and noise when used in areas of high AC magnetic field strength, such as in motor vehicles, on trains, and in sites with significant levels of electronic and electrical technology.  As a result, the system achieves outstanding speech quality across the whole spectrum of covert applications where standard inductive devices are inoperable.

The modulation scheme uses only carrier frequencies within the audio band, is highly tolerant to frequency drift, transmit coil response and mismatch of operational frequencies between transmitter and receiver. The receiver is programmed to decode only audio signals modulated onto the carrier frequency thus making it immune from inductively-coupled noise sources.   The system provides consistent performance over temperature and battery discharge level, while permitting compact construction.  No matching or pairing between transmitter and receiver is required.  The transmitter is entirely based on robust low-frequency electronics and is categorically not a radio frequency device.

 

A range of compatible coupling coils are available for neck, chest and shoulder locations as well as a car interface that will support both regular analogue and digital inductive devices and the VSB system simultaneously.
