It's a professional bug for the transmission of mono audio signal in digital mode.
The kit includes a bug housed in a small metal box, equipped with an external antenna, microphone and power supply. To use the system, simply insert the batteries into the power supply.
The kit bug encrypted digital uses an algorithm to 16 bits for the analog-digital conversion, compression and transmission of audio data intercepted. This ensures high signal quality and noise reduction, also thanks to the crystal controlled radio channel.
For optimum performance is recommended to add a receiver to the transmitter for radio control.
The receiver is equipped with a channel selector, volume control, level indicator signal and battery, connection for external antenna jacks for headphones and recorder.
