SZI 1029

The SZI 1029 is a high-power radiator for wideband or narrow-band signals from any modulator. Its mains unit automatically adapts to mains voltages of 85 – 265 V and mains frequencies between 50 and 60 Hz, the individual product variants only differing in the type of mains cable supplied. The only exception is the SZI 1029-24 which operates on 24 V DC. For 24-V equipment, mains voltage regulations are no longer applicable, thus making installations by audio-visual companies much easier.

All controls and connectors of the SZI 1029 are on the base. A 5/8“ thread with an adaptor for conversion to 3/8“ and 1/2“ threads makes for versatile mounting. If the radiator is to be stand-mounted, its cables are guided unobtrusively down the stand. For ceiling mounting, the SZI 1029 is simply turned upside down (the bottom faces the ceiling) and the cables are guided along the ceiling.

The 132 IR diodes of the SZI 1029 are arranged in independent groups of eleven. 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 radiator is operating and transmitting an IR signal. The radiator switches on auto- matically as soon as it receives an RF signal of at least 50 mV. When the RF signal is no longer present, the radiator switches back to stand-by. If both the red and the green LED are lit, the radiator indicates a malfunction: more than four diode groups fail to operate. The radiator will continue to operate at a reduced radiating power but it should be repaired as soon as possible.

The sockets and controls are on the base of the SZI 1029 (see diagram on the left). On each side, the radiator is fitted with a heat sink. When installing the radiator, care should be taken that these sinks are not covered and that the radiator is not mounted horizontally. The optimum position is vertical or almost vertical so that air can circulate freely through the cooling fins and heat is dissipated quickly. The modulator signal is fed to the BNC RF input. An automatic modulation control compensates for cable losses and ensures an optimum modulation level for the IR diodes. At the RF output socket (BNC) the signal can be daisy-chained to additional radiators.

The mono/multi switch increases the radiating power by 3 dB when set to “mono”. Thus, the coverage area is approx. 50 % larger, but at the same time, the THD becomes greater, which would lead to interference with higher channels in multi- channel operation. For this reason, you should only switch to “mono” for single- channel applications and use the “multi” position for multi-channel operation. The SZI 1029 radiator has a 5/8“ thread and is supplied with an adaptor for conversion to 3/8“ or 1/2“ threads. You will find suitable attachments such as mounting plates or table stands in the chapter “Accessories”. The radiator’s IEC mains connector can be secured by a steel clamp. The SZI 1029-24 variant is equipped with an XLR-4 connector as power supply socket.
