A). Rules for cable selection
TELIKOU intercom system adopts double-core shielded audio cable, one core is 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.
