MASTER LINK
BeoLink distribution covers the ability to distribute both audio and video
signals. In the Master Link system audio and control signals are
distributed by means of one single cable, whereas the distribution of
video signals requires a coaxial cable network. Only BeoLink compatible
products can be fully integrated in a BeoLink system, but previous system
products may be integrated to a limited extent, as described in the
chapter on Compatibility setups, page 17.
