UHF Wireless Simultaneous Interpretation/Conference System

System Components:
Transmitter
SPL-1600T: Body-pack transmitter, connecting with a headphone or a lavalier mic, especially adapt to remove outdoor application.
SPL-1600TM: Handheld transmitter, integrated with transmitter without antenna and a metal push-to- talk microphone.
WT-1600: Stationary transmitter with multiform jack connection, adapt to indoor application.Receiver
SPL-1600R: Portable wireless receiver, connecting with a earphone , especially adapt to remove outdoor application.
WE-1600: Built-in wireless receiver, installed on the council board, chair and any other places.
WI-1600: Stationary wireless interpreter unit, integrated with wireless receiver and microphone, is used for monitoring and speaking for interpreter.
Special Features:
1. Unique design of welcome-screen, editing and displaying salutatory, themes and LOGO.
2. UHF professional frequency, PLL synthesized design, an ultra-wide 40MHZ bandwidth design, 1599 frequencies be selected.
3. Switching language-channel quickly, displaying languages name / channel / frequency simultaneously.
4. Channel group design, with 32 channels in User Group, could adjust frequency and name in it.
5. Three-way communication broadcasting with combination of the units.
6."Digital Pilotone & Noise Lock" dual-squelch Circuitry.
7. 128*64 dot matrix double-color OLED display. display language name, channel group, channel,
frequency and lock Mode,etc.
8. RF track tuning filtering technic with SAW RF filter to get high anti-interference.
9. Wireless interpreter combines wireless receiver of minitoring with microphone of speaking.
10. Wireless interpreter that connecting hand in hand , turning off other microphones automatically.
when he is speaking. This could make the interpreter work by turns.
11. Operating range 300-500ft in open ground.
12. Adopt lead-free technics,according with RoHS Application:1. Tour guiding
1). One speaker with many listeners. ( Figure I )
The speaker's voices can be clearly heard bythe listeners. The number of receivers can be added at will.
2). Two speakers with many listeners.( Figure II )
Two speakers can service for listenerstogether and listeners can hear both speaker A and speak B.2. Simultaneous Interpretation
Speaker's voice is transmitted by one wireless transmitter.
Interpreters can monitor the speakers by one wireless interpreter units and translate the sound
to any need of language. And then transmit their transliteration to wireless transmitters with
different frequencies.
While visitors can take one portable wireless receiver to hear different languages via different
language channel.3.Simultaneous Teaching
1). RF Wireless communication, applied to simultaneous teaching, practice, formal simultaneous
interpretation and distance education.
2). Wireless simultaneous interpretation system & equipment - Simultaneous teaching applicationWith several students and a teacher in the Cabinet, they could study together in any ways.Chargers:
