Digital Infrared Transmitter Wireless Digital IR Interpretation System
The transmitter is the central element in the language distribution
system. It accepts analogue or digital input, modulates these
signals onto carrier waves and transmits these carrier waves to
radiators located in the room.
Order information
VIS-VLI700A-4 4 Channels Digital Infrared Transmitter
VIS-VLI700A-8 8 Channels Digital Infrared Transmitter
VIS-VLI700A-16 16 Channels Digital Infrared Transmitter
Main Features
In accordance with IEC 61603-7 and IEC 60914.
With the digital DQPSK modulation technology.
High-speed DSP processing.
The high frequency (2-6MHz, IEC61603 BAND Iv), is not affected by
the high frequency driving light interference.
Input level indication function, controller front panel LED lamp
can display the input state of the corresponding channel.
With 16 channel external audio input.
With 16 audio outputs, can be used to monitor or connect cassette
recording.
With 4 signal output interface (BNC), is used for connecting the
radiation panel.
The power input is 100V-240V, 50-60Hz. It has to undergo a high
voltage (3500V) test, to ensure compliance with safety standards.
The controller shell made of metal materials, line and the shell
strengthened with wire connection, ensure the capability of
anti-static 8000V.
