Sennheiser SZI-1015T
The SZI-2015T is a wideband infra-red modulator with an integral radiator for high quality audio operation. Due to its compact size and relatively high radiating power, the SZI-1015T modulator/radiator is an ideal choice for medium-sized rooms up to 400m, for covering recesses or for applications which require transmission of audio information to well defined zones, e.g. in cinemas, theatres, meeting rooms, offices, lecture theatres, conference rooms, board rooms, etc.

One transmitter can be picked up by several Stethoset receivers.
