4 Infra-Red Technology
Infra-Red Transmission
The SZI 1015-T is a powerful infra-red radiator with integrated modulator. Within a cordless IR
transmission system, it transforms the electrical signal of the audio source into invisible infra-red
light and radiates it into the room. In contrast to radio transmission systems, infra-red transmission
is restricted to the room, therefore, other systems can be used in neighbouring rooms without any
risk of interference.
Ǡ The SZI 1015-T modulator/radiator is switched on by the audio signal. Please use the balanced
XLR-3 input socket for connecting the SZI 1015-T to the audio source.
To connect additional SZI 1015 radiators, use 50 Ω RG 58 co-axial cables with BNC connectors.
Alternatively, you can also use cables without connectors with the barrier strip (RF output terminal).
Wideband
Wideband transmission systems are used for transmitting high-quality audio.
Areas of Application
Ǡ Any application which requires quality audio transmission, for example systems for the hard-
of-hearing in churches and theatres.
Propagation of Infra-Red Light
The propagation of the IR light emitted by the SZI 1015-T modulator/radiator is comparable to
that of normal daylight or artificial (lamp) light. Therefore, the infra-red light is subject to similar
conditions when it falls onto different surfaces and materials:
