The Tourguide transmitter SK 2020-D will allow you to deliver a highly professional guided tour. Combining the bodypack transmitter with an headworn or clip-on microphone, will give you total freedom of movement during your tour. You will have both hands free to describe an object, make a presentation and express your point. The transmitter can be easily and comfortably operated, and is highly robust. The back-lit display confirms channel choice, the radio signal and the status of the battery. Two jacks for the microphone and line ensure variable utilization. For example, you will be able to transmit an external audio source such as music from a portable CD player via your transmitter and continue to talk or mute the microphone.
