The Sennheiser SI 30 is a wideband IR modulator with an integral radiator. It can be switched between operation on Channel 1 (2.3 MHz), Channel 2 (2.8 MHz) and stereo operation.
The compact size and relatively low radiating power of the SI 30 modulator/radiator and its companion SZI 30 radiator offer an affordable and practical solution for use in smaller or medium-sized conference rooms, or for applications requiring audio transmission to well-defined zones, in public spaces such as museums, aquariums and galleries.
