Sennheiser SET810
The SET810 is a wideband infra-red modulator with an integral radiator for high quality stereo operation. Due to its compact size and relatively low radiating power, the S180 modulator/radiator is an ideal choice for smaller or medium-sized rooms up to 60mē, for covering recesses or for applications which require transmission of audio information to well defined zones, e.g. in meeting rooms, small offices, living rooms, etc.

One transmitter can be picked up by several Stethoset receivers.
