General Description
The SI 30 is a small- to medium-area master transmitter that can be switched from 2.3 MHz to 2.8 MHz or used simultaneously for two channel/stereo operation. Utilizing these higher-than-usual subcarrier frequencies, this system avoids the interference generated by electronically-ballasted fluorescent lights. With the capability of covering 750 square feet, the SI 30 can be used with up to three SZI 30 slave emitters for increased coverage. This cost-effective system is ideal for conference rooms, Houses of Worship, courtrooms and similar type rooms up to 3,000 sq. ft.
Features
- New, higher subcarrier frequencies to avoid interference

Glossary
| Input voltage range |
| Indicates the voltage range of the input signal within which a unit will work properly, i.e. as specified in its technical data. |
| IR diodes |
| High-quality gallium arsenide diodes used in IR radiators to transmit modulated infra-red light. |
| Modulation |
| The process in which one wave is varied by some parameter of another wave, for example, an RF carrier frequency that is modulated by an audio signal. Types of modulation include amplitude modulation, frequency modulation, pulse code modulation and pulse width modulation. |
| Nominal deviation |
| Also known as reference deviation. The nominal deviation has been fixed at 40kHz to be able to give comparable technical data. |
| Operating voltage (mains) |
| Gives the (mains) voltage range for which a unit has been designed. |
| Output impedance |
| Gives the internal impedance of an a.c. source. If the input of a subsequent load has the same input impedance, we speak of a matched impedance. The maximum power is delivered to the load. |
| RF output |
| Socket for feeding the transmitter signal to the antenna (system). Rack-mount transmitters most commonly feature a BNC type connector; for bodypack transmitters, various types of connectors are used. |
| XLR connector |
| Most common form of connector in audio studio technology. |
