PULSE AUDIO TRANSMISSION KIT

PULSE AUDIO TRANSMISSION KIT

This device is used to transmit audio intelligence via radio channel. The audio data is accumulated in the transmitter's internal RAM, and as soon as a certain threshold is reached, it is sent via RF via rapid packet transmission.

The transmitter has a metal case and has connections for external power supply, antennas (data channel and RC signal receiver), and external microphone. The receiver unit provides the reverse procedure: data packet reception - error correction - packet merging - digital-to-analog conversion.

Via the remote controller, you can adjust output power and mode selection (conversion sampling rate, packet transmission parameters and intervals). The receiver unit is equipped with sockets for earphones, line out and recorder control sockets, as well as low battery indicator.

ADVANTAGES OF USING

  • Quick data transmission makes transmitter almost impossible to detect for bug sweeping devices;
  • Signal is impossible to decode;
  • High audio quality;
  • Low power consumption.
