B-RTX
If listeners use personal hearing components without direct Auracast™ reception, they can use the »B-RTX EXPERIENCE« receiver. Headphones, earphones or neckloops can be connected via the 3.5 mm jack socket. The participants then receive the Auracast™ data stream with their respective hearing personal systems.
The »RTX-DUPLEX Licence« add-on enables the activation of Auracast transmitter mode (TX) for B-RTX Experience devices. This gives them transceiver status and allows them to be operated either as transmitters or receivers, depending on which mode is activated. The integrated 3.5 mm jack socket is used to connect a microphone.
When the »RTX-DUPLEX+ Licence« add-on is activated, it unlocks Auracast transmitter mode (XT) and media player mode (via microSD card slot) for RTX devices.
Auracast™ audio broadcast streaming is suitable for use in all environments – indoors and outdoors, stationary or mobile. Areas of application include guided tours in museums and exhibitions, at historical sites or in halls with unfavourable room acoustics, up to busy centre streets.
Contemporary technology combined with a user-friendly design characterises all devices in the B-RTX series. For example, the desired Auracast™ broadcast audio channel can be searched for and selected using the control elements. The robust design ensures a long service life.
The device battery is charged via the integrated USB-C socket or, depending on the number of devices, with the »B-SmartHive« or »B-Hive 4« chargers.
