The SK 3202 portable transmitter
The SK 3202 is a portable stereo transmitter, allowing you
to offer personal guided tours using your system.
The SK 3202 ensures excellent speech intelligibility even
over longer distances. There will be no crowding around the
guide; other visitors will not be disturbed by the guided
tour (and vice versa). The visitors to the tour can enjoy
complete freedom of movement.
A few mouse clicks are all that is required to configure the
portable transmitter and any number of receivers for a
guided tour. The portable transmitter is easy to use.
During a guided tour, the portable transmitter does not in-
terfere with the reception of Storage and Live Events. Using
the portable transmitter, the receivers participating in the
guided tour can be seamlessly switched between the guid-
ed tour and any Events.
Suitable receivers
The SK 3202 portable transmitter only works with the Sen-
nheiser EK 3202 receivers.
