datasheet user manual

Overview


The transmitter is the central device 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.
 

Features


● Compliant to IEC 61603-7 and IEC 60914 and the latest national standard GB 50524-2010
● Compatible with any other IR simultaneous interpretation system compliant to IEC 61603-7
● DQPSK digital modulation/demodulation technology
● Transmitting in 2~8 MHz frequency band eliminates disturbance from high frequency lighting systems
● Capable of distributing of 4,8 or 16 audio channels
● Auxiliary mode for distribution of music to all channels during a break
● Slave mode for distribution of signals from another transmitter allows multiple rooms to be used
● Radiator and system status indication via display and indicators
● Each transmitter can be assigned a unique name by the installer for easy identification in a multi-transmitter system
● Automatic distribution of emergency messages to all channels
● Automatic synchronization to the number of channels in use by the CLEACON system
● Each audio channel can be assigned a language name for easy identification
● The sensitivity of each input is adjustable, the audio level can be fine-tuned, and the audio input level indication is supported
● Flexible configuration of channels and channel quality modes: Mono, standard quality, maximum 16 channels Mono, perfect quality, maximum 8 channels Stereo, standard quality, maximum 8 channels Stereo, perfect quality, maximum 4 channel
● With 16 interpretation output channels for recording
● Universal power facility allows worldwide use
● Conference hall privacy; the congress venue itself acts as a barrier to infrared signals escaping and being overheard, as infrared is unable to pass through opaque objects such as walls
● Suitable for various kinds (small/medium/large international) of conference halls and outdoor venues
● Can directly connect with interpreter desk VIS-INT64
● With 16 channel analogue audio input and 16 channels analogue audio output.
● 2 transmitters can work as master and slaver mode for 32 channel language distribution
● Connecting to Dante network by optional Dante port
