It is slim and compact but can cover areas of up to 80 m2 in mono operation. The integrated modulator uses stereo wideband modulation. When the audio signal at the SI 30 input exceeds a certain threshold value, the modulator/radiator is switched on automatically. It switches off again when there has not been an audio signal for about 2 minutes. Transmission is indicated by a green LED on the left of the front panel. The radiator of the SI 30 comprises 11 IR transmission diodes connected in series. The AF input of the SI 30 is a 3-pin Texas socket located at the back of the unit, on the left. It is an unbalanced stereo input, so you should not use long connection cables. A 2 m connection cable with 3. 5 mm stereo jack to a 3-pole Texas connector is supplied as standard. An automatic modulation control adapts to audio signals between 45 mV and 4 V. This process is effected over a period of about one minute, so that short speaking pauses do not entail a greater amplification. Problems may arise when you are working with microphones and very different signal levels. Longer breaks can lead to a strong increase in amplification. When connecting the SI 30 to headphone sockets of TV sets or similar sound sources, you should adjust the level to a medium value. With the channel selector switch, you can choose between channel 1 or 2 transmission or stereo operation. In mono operation, the integrated radiator and all connected radiators can cover a greater area. For mono transmission, choose the frequency suitable for the receiver, e. g. 1 1 2 3 4 2 3 4 The RF output for connection of additional radiators is designed as a 3. 5 mm mono jack socket. [. . . ] Such a system can consist entirely of SI 30 and SZI 30. As auxiliary radiators in combination with the SZI 1029, for covering room niches and recesses. As "island solutions" ­ e. g. Such a system can economically be implemented using the SI 30. [. . . ]
