Features :
The working principle of the VA-6912 series simultaneous interpretation system is to use infrared transmission for language distribution. It is highly respected for its super confidentiality. It is the advanced transmission method in the infrared simultaneous interpretation system on the market.It is suitable for all kinds of small, medium and large conference rooms and outdoor places which require high confidentiality. The VA-6912/06 can simultaneously modulate and transmit up to 6 languages. Participants only need to have a lightweight receiver to listen to the speech by selecting the channel.
Highly confidential to prevent external malicious interference and eavesdropping.
Suitable for small, medium and large international conference halls and outdoor venues. With automatic level control (ALC).
Superior anti-interference can be interfered by lighting and wireless communication equipment
Easy and fast connection, reducing engineering complexity and engineering costs
Adopt the advanced phase-locked loop technology
Multiple sets of transliteration output channels for recording
Multiple voice input channels for simultaneous modulation in 6 languages
The special test function of the host can generate a variety of different frequency information corresponding to the number of languages, which is convenient for system debugging.
With input level indication function, it can directly display the input level.
