About Sengled SR2020-D-US Kit

- SR 2020-D-US Transmitter -
SR 2020-D, multiply gifted! For each of your productions, the compact high-tech transmitter SR 2020-D will provide perfect audio in exactly the right way. It allows for conferences or presentations to be interpreted simultaneously in up to 8 languages. Other audio content can be selected from CD, DVD or your IT network. Of course, you can connect microphones for announcements, and the system will even follow you on bus or boat tours.

The transmitter is operated very easily and comfortably. Important parameters such as channel selection and line/mic input levels can be checked on the back-lit display.


- TourGuide HDE 2020-D-II Receiver -
HDE 2020-D stethoset Tourguide receiver is the comfortable to wear receiver of the digital Tourguide System 2020-D. This truly unique device integrates both the receiver and headphones and delivers a number of advantages for you. No longer will your audience have to carry any more equipment than is absolutely necessary. Being a one piece device, they will no longer risk a tangle of cables! The powerful battery ensures that the device will work for up to 8 hours. Regardless of whether you are providing your tour in a big city or a large corporation, Tourguide 2020-D will ensure that your tour will proceed without interruption.

The stethoset receiver automatically deactivates itself the moment that it is taken off, meaning battery life will be preserved. No longer will the Tourguide need to check all of the sets after one tour finishes and before the next tour starts. Your tour participants will be able to individually adjust the volume through a rotary control on the receiver, without the need to even take the device off. An LC display will clearly confirm the volume, battery status, quality of reception and the channel being listened to. Channels can easily be set and adjusted by using the middle buttons. The reception range is about 100 m if your tour is outdoors and about 50 m if your tour is indoors.


- ELZ 2020-20L Charger Case -
The EZL 2020-20L charger case has been designed to be highly user-friendly. It acts as both the storage case for all equipment and charging station for the Tourguide receivers and transmitter. Twenty charging bays for HDE 2020-D or EK 2020-D receivers and two charging bays for the transmitter or its rechargeable battery pack-are provided. Truly impressive feature of the charging case is the Copy button.
