Overview
The Sennheiser SI 30-1500 Single System Package includes the crucial components you need for configuring a complete IR system capable of providing coverage in medium-sized rooms up to 1,500 square feet.
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.
The SZI 30 is a DC-powered IR emitter designed to be slaved to an SI 20 transmitter to increase the effective coverage area of the SI 20. Up to three SZI 30 units can be added to an SI 20.
