Encrypted audio bug transmitter on telephone line. A guarantee of safety and reliability for your audio interceptions!

The ENKPL-TD transmitter is used to transmit encrypted audio information by using a landline telephone cable. The product applies the adaptive-delta modulation (ADM) method for encryption of the audio informations. When ENKPL-TD is connected on a subscriber telephone line, it does not interfere with the normal operation of the telephone set which can normally dial and ring, and does not affect the overall quality of the communication.

The data signal is generated via a compact ENKPL-TD transmitter. ENKPL-TD is designed as a small module with an external microphone and lead-out wires used for parallel connection to the landline. The operating power is supplied directly from the DC 6-60V line cable.

ENKPL-TD informations receiver is housed in a metal case. The receiver features a battery compartment with housing for four rechargeable AAA batteries (1.2 V) or four AAA alkaline cells (1.5 V). As an alternative, it can also be powered from an external power supply unit. When the external power supply is plugged in, the batteries are automatically disconnected to prevent unwanted consumption.

The receiver connection to the telephone line can be done in two ways: a) parallel to the line and b) serial connection with the second subscriber line, switched with the first via a ENKPL-BUK switcher & amplifier unit (optional). The ENKPL-BUK amplifier, also working as a switch, provides amplification and transmission of intercepted information from one telephone line to another, avoiding going through a switchboard. ENKPL-BUK (size 50 x 50 x 15 mm) is powered directly from the telephone line, or through an external power source.
