SI30 Modulator & Radiator

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-sizedrooms, for covering recesses or for applications which require transmission of audio information to well defined zones, e.g. in museums.
