Page 6: Overview
1. Overview eless distribution of audio signals via infrared radiation. It can be used in a simultaneous interpretation system for international conferences where multiple languages are used. To enable all participants o t understand the discussion, interpreters simultaneously translate the speaker’s language as required. These interpretations are distributed throughout the conference venue, and delegates select the langu age of their choice and listen to it through headphones. -

Page 17: Planning
2.3 Planning The system is based on transmission by modulated infrared radiation. Infrared radiation forms part of the electromagnetic spectrum, which is composed of visible light, radio waves and other types of radiation. It has a wavelength just above that of visible light. Like visible passes through translucent materials such as glass. -
Page 18: The Footprint Of The Radiator
2.3.3 The footprint of the radiator The cross section of the 3-deimensional radiation pattern with signal is strong enough to ensure proper reception, when the receiver is directed towards the radiator. As shown, the size and position of the footprint depends on the mounting height and angle of the radiator. Radiator mounted at 15°... -
Page 19: Position The Radiator
2.3.4 Position the radiator Since infrared radiation can reach a receiver directly and/or v this into account when considering the positioning of the radiators. Though it is best if receivers pick up direct path infrared radiation, r minimized. Radiators should be positioned high enough not to be blocked by people in the hall (see the Infrared signal blocked by a person in front of the participant Infrared signal not blocked by a person in front of the participant the participant is situated clear from obstacles and walls, so a combination of direct and diffused radiation... - Page 20 For concentrically arranged conference rooms, centrally place da , ngled radiators located high up can ting surfaces, such as a darkened path infrared radiation from radiators positioned in front.

Page 21: Cabling
2.3.5 Cabling Signal delay differences can occur due to differences in the cable length from the transmitter to each radiator. In order to minimize the risk of black spots, use equal cable length from transmitter to radiator if possible (see t Radiators with equal cable length When radiators are loop-through connected, the cabling between each radiator and the transmitter should ifferences in cable signal delays can be... -
Page 22: Set The Delay Switches
2.3.6 Set the delay switches As described in section footprints and black spots, differences in the delays of the signals picked up by the receiver from two or more radiators can cause black spots as a result of the multi path effect. To compensate the signal delay differences, the delay of each radiator can be increased. -
