Beosystem 5500

The Beosystem 5500 1s easy and very convenient to use - you can in fact
operate the whole system without leaving your chair.
The Master Control Panel 5500 is the key to the system and it communi-
cates with the brain of the system, the Beomaster 5500. Together they form
the basis of the system. The other units in the system, the Beocord 5500, the
Beogram 5500 and the Beogram CD 5500, are modules with which you can
extend your Beosystem 5500.
The Beomaster 5500 1s a so-called Beolink product, which means that it can
be used as a master in a Bang & Olufsen Beolink system. In a Beolink
system video and audio products are interconnected and they can be
operated using only one remote control unit — the Beolink 1000. For further
information about setting up and operating the Beolink system, please refer
to the special Beolink manuals.
