Simultaneous Interpretation System for Teaching Spl-1600 Series

System Introduction of wireless simultaneous interpretationSoolai wireless simultaneous interpretation system / tour guide system (1600 Series) is composed of several different transmitters and receivers, suitable for indoor and outdoor environments, you can choose them based on your requirement.It is widely used in wireless tour guide, simultaneous interpretation, simultaneous teaching and stage monitoring. It is the best in the same kind of products, the ultra anti-interference ability, the best environmental adaptability and the clearest sound.Unique design of welcome-screen, salutatory and LOGO can be edited and displayed in main devices' display screen.Switching 32 channel (language) quickly, displaying languages' name/channel/frequency Simultaneously. with optionally setting of 2-32 channel switch,each channels' frequency and name can be set independently. Language can be selected by user own in simultaneously interpretation application.Soolai first launched the wireless interpreter WI-1600 in the industry, convenient for interpreter. It combining wireless receiver of minitoring with microphone of speaking.The unique design of hand-to-hand connection between multiple interpreters can realize the alternate rotation of multiple people, to reduce the pressure and improve the quality of simultaneous interpretation services.

Application Samples of wireless simultaneous interpretationTour guideOne speaker with multiple listeners. ( Figure I ) The speaker's voices can be clearly heard by listeners. Quantity of receivers can be added at will.Two speakers with multiple listeners. ( Figure II ) Two speakers could service for listeners together and listeners could hear both speaker A and speak B.A multi-person speaker recommended to use the full-duplex tour guide system TG-900.
Simultaneous Interpretation(Portable, suitable for outdoor use)Speaker's voice can be transmitted by a portable transmitter SPL-1600T.Speaker's voice can be monitored by interpreters through portable receiver SPL-1600R, and interpreters interpreted to different languages, and transmitted to visitors/receivers by portable transmitters SPL-1600T.Visitors will hear the interpretation by portable receiver SPL-1600R.
Simultaneous Interpretation(Desktop, suitable for indoor use)Speaker's voice will be transmitted by wireless stationary transmitter WT-1600.Speaker's voice can be monitored by interpreters through stationary interpreter unit WI-1600, and interpreters interpreted to different languages, and transmitted to visitors/receivers by WT-1600.Visitors will hear the interpretation by portable receiver SPL-1600R.
Simultaneous teachingRF Wireless communication, applied to simultaneous teaching, practice, formal simultaneous interpretation and distance education.Students could concentrate learning, personal practice, group interpretation, simultaneous interpretation and do other learning activities, suitable for school simultaneous interpretation teaching and training.
Welcome display (Global originality)It could edit the pattern or character of any country.Professional edit software,can be edit and upload by PC.Global original: promote enterprise's brand image, improve service quality of enterprise.
Switching (language) quickly Users could select the language/channel by their own.Language'name/channel/frequency can be switched simultaneously.optionally setting of 2-32 channel switch,each channels' frequency and name can be set independently.
