PREFACE
This handbook deals with Bang & Olufsen's Local Control System and AV system, paying special attention to the installation requirements applying to them. Consequently, this handbook is especially addressed to dealers and installers.
Any product, for example a stereo system, a PC, a natural gas system, etc . t h a t h a s t o b e i n c o r p o r a t e d i n t o a n e t w o r k n e e d s t o h a v e c e r t a i n requirements satisfied by the surrroundings in connection with its installation,
These requirements must ensure the optimal operation of the system after installation.
The same apllies to Bang & Olufsen's Local Control System and AV system.
Although the requirements are not many, it is essential that they be known since compliance with the basic requirements often determines whether or not the system is able to operate once the installation has been completed.
This handbook gives a brief and precise introduction to the basic roles for the product programme in 92/93 and for-future programmes. The rules must be observed in connection with the installation of a Local Control System and/or an AV system.
The handbook has been designed partially as a reference book but the entire handbook should be read in order to obtain the total overview. Only then will it serve its purpose as a reference book

READING INSTRUCTIONS
The hardware (plugs, cables, X-tra kits, etc.) used for connecting Bang & OIufsen's products into a system is always the same, no matter if it is a
Beocenter 9500 and an MX 5500 that have to be connected or if it is a
Beomaster 7000 and an MX 5500, for example.
The handbook employs various symbols to illustrate audio products, video products and speakers. Unless otherwise stated in the text, these symbols merely have to be understood as covering one of these product areas and not as the specific product which the illustration may depict.
Since the handbook is focusing particularly on the basic rules in connection with the installation of the systems, variables which are specific to particular products have been omitted to the greatest possible extent, This means that the handbook will always be relevant in connection with installation of local
Control Systems and AV systems; both with regard to products launched prior to the publication of the handbook and products that will be launched later.
The basic rules applying to the AV and Local Control Systems will always he the same.

GENERAL DESCRIPTION
What is an AV system?
What is a Local Control System?
When a Bang & Olufsen audio system and video system are interconnected, they make up an AV system.
An AV system offers a number of possibilities which are not accessible if the products are placed as independent products. For example, in an AV system the sound can be moved from the TV to the audio system speakers; a function that proves its excellence when the sound and the picture have to merge into a higher synthesis. The sound from the audio system can similarly be moved to the TV speakers. This function comes in handy if you wish to record sound from the audio system on the video tape recorder, for example.
The interconnection of the audio and video systems is furthermore a condition for distributing and operating video sources (antenna, cable, decoders and video tape) to and from other rooms in the house.
Local Control System is a common denominator for those elements which enable the distribution of sound and picture to different rooms in the house. In other words, the Local Control System enables operation and enjoyment of a centrally placed audio/video system from different rooms in the house.
Some of the basic elements included therein are:
The obligatory 7-conductor MCL cable and X-tra kits (transceivers, MCL 2A relay boxes and MCL 2AV panels).
So, with a centrally placed audio system and a Local Control System it is possible to listen to and operate e.g. a radio, CD player, tape recorder, etc. from other rooms.
If the centrally placed audio system is connected with a video system, thereby forming an AV system, a host of new possibilities are made available. This further allows the distribution of video sources to other rooms. In addition to listening to and operating the audio system from different rooms, it is also possible to watch, listen to and operate the video system from other rooms.
For example, you can listen to the TV news through the speakers in the kitchen; or you can watch and operate cable TV and the video tape recorder via the TV in the bedroom. Encoded cable TV programmes can also be watched in the local room, provided that a decoder is connected in the central room. Another possibility is to listen to the radio via the TV in the bedroom, for example.

Miscellaneous
Below you will find a description of the individual elements included in the Local Control system as well as their scope of application
X-TRA SPEAKER KIT
The X-tra speaker kit contains an MCL 2A relay box, a transceiver. a Beolink 1000 wall fixture and fittings for installation.
The X-tra speaker kit is used in those rooms where you wish to have sound via passive speakers. The Beolink 1000 wall fixture is intended as a storage place for the remote control terminal.
In addition to the content of the X-tra kit and the passive spacers, some
MCL cable and perhaps some plugs and connection boxes are required (
See the section on installation for further information, if required.)
When using the X-tra speaker kit they volume adjustment is common with that in the Central room and any other X-tra speaker kits.
