10.11 Language Distribution Equipment

10.11.1 Introduction

Distribution of interpreted languages to delegates can be handled using two different methods of language distribution - Wired and Wireless.

1. Wired

The distribution of interpreted languages through language channels can be handled using the standard DCN system cabling. Delegates with contribution units fitted with channel selection facilities can listen to the language channel of their choice. Stand-alone channel selector units type LBB 3524/

xxand LBB 3526/10 are available for use in both portable and fixed installations. In fixed installations the channel selector units can be installed in to table-tops or armrests.

Integrus digital infra red system

An infra-red system comprises an infra-red transmitter, several radiators and infra-red receivers carried by delegates. A well balanced installation should be based on sufficient direct radiation intensity for the area to be covered. Each situation demands its own solution to maintain a high enough signal-to-noise ratio in order to ensure good clear reception within the conference area. Optimally positioned radiators will both minimize installation and running costs.

For further detailed information on installing an Integrus digital infra red system, particularly on positioning radiators and operating the system, refer to the Infra-red Language Distribution Systems Installation and Operating Instructions manual, Code No. 3122 475 2201x.

2. Wireless

For those delegates with no access to a channel selector, an infra-red wireless distribution system can be used. Using this system infra-red signals carrying language channels are transmitted from wall or ceiling mounted radiators, and received by delegates using personal infra-red receiver units.

The infra-red language distribution system comprises of an IR transmitter, a Multi-channel Audio Interface Unit LBB 3423, one or more radiators and personal IR receivers with channel selectors for selection of the required language channel.
