    MC9169 infrared simultaneous interpretation system

    Summary of system composition and equipment functions

    The operating principle of the infrared language assignment system is to assign language with infrared transmission.

    It is much recommended due to powerful confidentiality and is the most advanced transmission mode of the infrared

    simultaneous interpretation system on market. It is applicable for small, medium and large-sized conference rooms

    and outdoor venues with high requirements on confidentiality.

    The system modules and transmits up to 12 languages simultaneously and the conference participants receive the

    speeches by selecting the channel with a small receiver. (The product offers 6, 8, 10 and 12 channels available).

    Supreme confidentiality to keep off malicious interference and eavesdrop.

    Applicable for small, medium and large-sized international conference hall or outdoor venue.

    Automatic level control (ALC) function is available.

    Super powerful anti-interference capability is not disturbed by light and wireless telecommunication apparatus.

    Simple and quick connecting to simplify project installation and lower project costs.

    The most advanced lock-phase locked loop technology.

    The shape conforms to the human engineering science, exquisite and smooth.

    Multiple groups of interpretation output channel for recording.

    Multiple language input channels modulate and transmit up to 12 languages simultaneously.




    Interpreter’s microphone (MC9169F)


    MC9169 infrared simultaneous interpretation system


    Earmuff earphone is used to monitor the speech.

    Individual volume adjustment and automatic whistling function are available.

    The same channel is interlocked to ensure that the channels are corresponding to languages.

    Cough sound elimination function is available. When the interpreters cough, the cough sound can be eliminated.

    When the lecturers speak too fast, press the SLOW key to request the lectures to slow down speech.

    The REPLAY translation switch (REPLAY) is available. When the interpreters cannot understand the lecturers’ speech,

    a second interpretation can be carried out by monitoring other interpreters’ interpretation results.

    Connected to infrared language assignment system.

    Two interpreters use the same interpretation unit in turns.

    12 language simultaneous interpretation function (including original voice channel) is optional.
