Standard cables are generally constructed using a male connector at one end and a
female connector at the other end. This allows several cables to be interconnected to
create longer cable runs.
Audiocom power supplies use a 3-pin male Neutrik connector for
each channel. Audiocom wallplates use male Neutrik connectors.
Audiocom master stations, speaker stations and belt packs
also typically provide both a male and female Neutrik connector for each intercom
channel. This permits loop-through connection of several intercom stations using the
standard cables.
Use second drain wire if available, or add an extra section of wire.
