The RA 15 series of DIS Infrared Radiators are used for powerful distribution
of channels in a simultaneous interpretation system. It transmits up to 18
channels in FM sound quality by means
of invisible light.
No fan cooling. RA 15 models are
cooled by convection principle.
The RA 15 series of infrared radiators
are based on a revolutionary new technical modulation principle with almost
100% modulation resulting in extreme
large coverage.
Most modern infrared transmitting diodes increase the IR-radiated modulated power to 30 Watts. Now much
larger surface areas and distances may
be covered.
Receivers output better than 40 dBA,
i.e. free from perceptible noise.
(Please, see the DIS Infrared Covering
Guidelines for more specifications)
The RA 15 models provides reliable
illumination from small scale meeting
rooms up to very large conference halls.
The RA 15-30 model covers up to
2.580 sq.m./ch., when used with the
high sensitivity DIS IR 15 Infrared
Receivers.
The RA 15 models features:
Recessed high power diodes of latest GaAs/GaAlAs type.
Close to 100% modulation.
Small cabinet size in black or white
metal housing with low weight per
radiated Watt and adjustable swivel
bracket for easy mounting.
The RA 15 models has a built in power
supply. It is automatically activated by
high frequency signals emitted by a
DIS Infrared Transmitter.
RG58, coaxial cables for signals and
power cords allows daisy chaining of a
maximum of 25 numbers of radiators.
Angle of half intensity 44 deg.
Extreme large coverage. Covers almost 10,000 Sq.m./ch.
