The SI 20 is a small- to medium-area transmitter, which can be connected to audio components via an 1/8" or 1/4" plug. It has the ability to switch transmitting frequencies from 95 kHz to 250 kHz or both for two channel/stereo operation. Capable of covering approximately 750 sq. feet, the SI 20 is sufficient for small screening rooms, or as a monitor transmitter for the projectionist at movie theaters. Coverage can be increased with the addition of DC powered Sennheiser SZI-30 slave emitters. A system with one SI 20 transmitter and up to three SZI30 slave emitter panels is ideal for small- to medium-sized theaters where a SZI 1029-T or SI 1013/SZI 1029-T system would be too large.
