SZI 1029
IR Audio Transmission Technology |
General Description
The SZI 1029 is a 5-W high-power radiator for use with all wideband and narrow-
band modulators. The radiator is automatically switched on by the RF carrier and
can cover areas of up to 800 m
transmitting diodes have been arranged in 12 independent groups to ensure
re liable transmission. A malfunction indicator is triggered when the radiating power
is reduced by more than 30 %.
Features
High-power radiator with a maximum coverage area of 800 m
RF output for connecting additional radiators
Automatic on/off function
Versatile installation due to 5/8", 3/8" and 1/2" threads
Excellent reliability due to 12 independent groups of transmitting diodes
and malfunction indicator

- Page 2 Modulators/Radiators General Description With a radiating power of 10 W, the SZI 1029-10 is the most powerful Sennheiser radiator. Like the SZI 1029, it is fitted with an automatic on/off function, indepen- dent diode groups and a malfunction indicator – but with twice the amount of IR...
- Page 3 The operational status of the diodes and the radiator is indicated by a green and a red LED at the front. If only the red LED is lit, the radiator is in stand-by mode and a mains voltage is present, but there is no RF carrier. If only the green LED is lit, the Green LED: radiator is operating and transmitting an IR signal.

30˚ 30˚ 40dB The polar diagram on the left is that of the SZI 1029. You can see that the signal- to-noise ratio decreases the further you go away from the radiator. Eventually, 40˚ 40˚ the noise becomes so loud in relation to the useful signal that the squelch in the IR receiver mutes the audio output.
