used for transmitting audio signal, another core is used for transmitting DC power
or control signal, and the shielded layer is used as common line for audio and
power supply. To decrease resistance of common line and crosstalk interference,
the cable with larger cross section area should be used. When it is used in fixed
way, the cross section area of single line should be at least 1.5mm

, when it is
used in mobile mode, the cross section area of single line should be at least
0.75mm

. When the cable is longer, the cross section area of cable should be
larger. If the cable has more than 2 cores, it is recommended to use the additional
core as common line.

The standard TELIKOU intercom cable is connected with a pair of 3-pin XLR
connectors, one male and one female. If longer cable is required, you can connect
several cables together with head-end method.
