INFRA-RED TECHNOLOGY

The SZI 1029 is a high power infra-red radiator. In a cordless infra-red

 

sound transmission system it transforms the electrical signal delivered

 

by an infra-red modulator or by an audio source into invisible infra-red

 

light and radiates this IR light into a room. In contrast to radio

 

transmission infra-red transmission is limited to the room, thus other

 

systems can be operated in neighbouring rooms without interference.

 

￿ The high-power radiator SZI 1029 is switched on by the IR carrier

 

signal that is produced by the modulator. Commercially available

 

50 coaxial cables with BNC connectors are used for feeding

 

sig nals from the modulator to the SZI 1029 radiator.

 

The infra-red radiator diodes in the high power radiator respond to the

 

received signals and radiate modulated infra-red light. Depending on

 

the model the radiator delivers a radiating power of 5 or 10 W

 

(see AVAILABLE MODELS).

WIDEBAND

Infra-red wideband transmission systems are chiefly used for transmitting

 

audio signals in hi-fi quality.

 

The two available wideband channels (2.3 MHz and 2.8 MHz) are

 

internationally standardized and are either used for two mono channels

 

or for stereo transmission.

NARROW-BAND

Infra-red narrow-band transmission systems allow the transmission of

 

up to 32 mono channels with a slightly reduced audio frequency response.

 

They are ideal for multi-channel interpretation systems and multilingual

 

information systems.

AREAS OF APPLICATION

￿ Conference and simultaneous interpretation systems

 

￿ High quality cordless sound transmission in recording studios

 

or for hi-fi systems

PROPAGATION OF

The propagation of the infra-red signal radiated by the SZI 1029 can be

INFRA-RED LIGHt

compared to the propagation of normal daylight or artifical (lamp) light.

 

Thus it is subject to similar conditions when it falls onto different

IMPACT OF CURTAINS,

Dark and heavy materials, curtains, carpets, panellings, and wall

CARPETS, AND PAINTS

 

coverings tend to absorb the light, a good reception can only be

 

 

achieved in direct line of sight of the infra-red radiator.

 

Roughcast and strongly structured wallpapers (such as woodchip,

 

 

embossed or fabric papers) reflect the light unevenly but allow a

 

 

more uniform propagation of the infra-red signal.

 

Smooth and bright walls, smooth tiled floors and windows are

 

 

highly reflective and are thus favourable for the propagation of in

 

 

fra-red light.

Different wall paints may reflect infra-red light differently although they have the same colour. This is due to the type and thecomposit- ion of the paint pigmentation.

The power which is necessary to irradiate a room varies accordingly.
