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.
- Compliant to IEC 61603-7 and IEC 60914
- 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
- Adjustable sensitivity for each input to enable fine tuning of audio levels, support levels indicating of audio input
- 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 mains 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
- Support the interpreter unit connection directly(by optional firmware VIS-VLI700-FW)
- Support 16 channel analogue audio input and 16 channels analogue audio output.
- Support 2 transmitters can work as master and slaver mode for 32 channel language distribution
- Support optional Dante port for connecting to Dante network
Controls and Indicators
- Graphic LCD with back-lighting displays status and menu of the system configuration, supporting multi language menu
- Four buttons for configuration
- Channel active indicators
Interconnections
- 2 female XLR connectors for external audio inputs to connect auxiliary balanced audio signals such as music, floor language or emergency audio signal
- 16 audio signal output connectors (phoenix sockets) for output multi-channel audio
- 16 audio signal input connectors (phoenix sockets) to connect external unbalanced audio input signals
- 6 BNC connectors for output HF signal to radiator. To each connector, up to 30 radiators can be connected
- 1 BNC connector for receiving HF signal from another transmitter
- Audio-Link Port for connecting to Interpreter Unit(optional firmware VIS-VLI700-FW) or VIS-DCP2000 or VIS-DCP1000 Congress Main Unit
- DANTE port for connecting to Dante network for the digital audio(Optional VIS-DANTE module)
- Ethernet and RS232 ports for connection to computer
- Emergency signal interface: when the public emergency system is active, alarm signal can be fed to all channels automatically
- Power supply socket
