INCA TXF-RC WIRELESS AUDIO TRANSMITTER 1.1 Introduction This document describes the general functions and performance of the Spectronic INCA TXF-RC transmitter. Information on items of a specific delivery is to be found in a separate document, stating TX frequencies and remote control address codes of the individual units. -
Page 4: System Concept
1.2 System Concept 1.2.1 General The INCA TXF-RC is a series of wireless audio, remote controllable, small sized VHF transmitters intended for concealed room monitoring or as body transmitters. The TX unit comes with flying leads for the battery connection and the antenna terminal has a female MMCX-connector. -
Page 5: Application Note
The scrambler has been added for greater security, and to avoid listening in by unauthorised persons. It is based on simple frequency- inversion techniques due to the very low power needed for that sort of circuit. In the scramble mode, the audio frequency response, as well as the signal to noise ratio, are somewhat minimized compared to the unscrambled mode. -
Page 6: Transmitter
The carrier frequency is OOK (on off keyed) modulated and the system provides up to 4096 different address codes. The Spectronic X-IDER remote-control transmitter is used to send the different codes for setting up the TX. -
