SI 30 - Two channel switchable/stereo IR transmitter (2.3/2.8 MHz), requires NT20-1-120 power supply (order separately), covers 750 sq ft (mono) or 375 sq ft (stereo) (9.0 oz)

The SI 30 is a wideband 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. Due to its compact size and relatively low radiating power, the SI 30 modulator/radiator and the SZI 30 radiator are an ideal choice for smaller or medium-sized rooms, for covering recesses or for applications which require transmission of audio information to well defined zones, e.g. in museums.
