Sennheiser HDE 2020-D-II US Stethophone Receiver
The HDE 2020-D stethoset Tourguide receiver is the comfortable-to-wear receiver of the digital Tourguide System 2020-D. This unique device integrates both the receiver and headphones, offering several advantages. Audience members no longer need to carry additional equipment, and the one-piece design eliminates the risk of tangled cables. The powerful battery ensures the device operates for up to 8 hours. Whether conducting a tour in a big city or a large corporation, the Tourguide 2020-D ensures the tour proceeds without interruption. The stethoset receiver automatically deactivates when removed, preserving battery life. This feature eliminates the need for checking all sets after one tour and before the next. Tour participants can individually adjust the volume through a rotary control on the receiver without removing it. An LC display clearly shows the volume, battery status, reception quality, and the channel being used. Channels can be set and adjusted easily using the middle buttons. The reception range is approximately 100 meters outdoors and about 50 meters indoors.
