Infrared simultaneous transmission system

System overview:

SINGDEN infrared simultaneous interpretation system is a professional voice conference system that provides instant translation for multi-language conferences. Its working principle is to use infrared ray to achieve multi-channel voice transmission. It is a language distribution method that meets international conference standards and is the most commonly used transmission method in wireless language distribution systems on the market. Infrared simultaneous interpretation system has strong confidentiality, eliminate external malicious interference, to ensure that participants can clearly and smoothly receive the content of the speech. The system can simultaneously modulate and transmit up to 12 languages, participants only need to be equipped with a lightweight receiver, through the selection of channels can receive the required language, the system has been widely used in various scale of government and business meetings.

Main Transmitter

features:

High confidentiality, eliminate external interference and eavesdropping;

Suitable for small, medium to large international conference halls or outdoor venues;

Automatic level control (ALC);

Strong anti-interference ability, free from the interference of lighting and wireless communication equipment;

The connection is simple and fast, reducing the difficulty of the project and reducing the project cost;

Adopt the most advanced phase locked loop technology;

The appearance design is ergonomic, delicate and smooth;

It can be used for recording with multiple audio output channels;

With multiple groups of voice input channels, it can simultaneously modulate and transmit up to 4 languages;

With input level indication function, can directly display the input level size;

It can be installed in a standard 19-inch cabinet.

interpreter console

Interpreter station features:

New CNC design;

Use ear-over-ear headphones to monitor speech;

With personal volume adjustment and automatic whistling function;

With the same channel interlock function to ensure the one-to-one correspondence between the channel and the language;

With antitussive function, when the translator coughs, it can prevent the cough sound from coming out;

When the speaker speaks too fast, you can press the request button (SLOW) to ask the speaker to slow down;

Has an indirect translation switch (REPLAY). When translators do not understand the speaker's language, they can listen for other translations. The translator's translation is translated a second time;

Can be used with connected infrared language distribution system;

Two translators can take turns using the same translation unit;

Simultaneous interpretation in 4 languages (including acoustic channels).

同传接收单元

Characteristics of simultaneous receiving unit:

Exquisite and smooth appearance design, ergonomic;

Lightweight receiver, used with headphones, so that users feel relaxed and comfortable;

Each channel does not interfere with each other,4 channel language selection (roll up loop);
