DIGITAL LINE CARRIER BUG

BUG TRANSMITTER WITH DIGITAL CODIFICATION

This system is designed for room monitoring and digitally encrypted transmission of the audio intelligence on subcarrier frequencies via AC 220 V, 50 Hz Mains.
The digital channel encryption keeps the transmitted data safe from interception. Analog-digital conversion is based on the adaptive-delta modulation (ADM) method. The transmitter comes as an unpacked module, with cables for connection to an external microphone and AC 220 V mains.

This kind of transmitter uses three different subcarrier values. Up to three transmitters with different subcarrier values can operate at the same time in a location.The transmitter can be connected in parallel to 220 V mains, in any point and with any polarity. The receiver is a separate module, housed in a metal case with cables for mains connection, earphones, optional recorder and external power supply.

On the receiver front panel you can find the knobs for tuning and volume control, and the on-off switch. The transmitter features a built-in delta modulation decoder. Thanks to the subcarrier high value, receiver and transmitter can be placed on two alternative phases of the mains, thus significantly reducing any interference in the audio channel.
