    MC7120 Digital frequency shifting microphone management

    The frequency shifting amplifier for general education is a complete set of professional amplification equipment tailored for school rooms,

    also satisfies sound amplification in conference rooms of courts, government authorities, enterprises and governmental authorities

    and carries high performance price ratio. In terms of particularity of medium and small-sized public sites, it solves difficulties of sound

    amplification stability, sensitivity and sound amplification articulation, effectively inhibits sound feedbacks, significantly weakens microphone

    whistling and ensures high-quality sound amplification.


    Technical characteristics

    1. Included with 24Bit A/D and D/A conversion; 24-bit DSP processor and 48KHz high-speed sampling;

    2. Feedback inhibition composed of 4 parameter filters and full-digital DSP frequency shifting;

    3. 6-channel microphone input, MIC1-MIC4 with 48V phantom power supply. (MIC1-MIC4 1/4 available);

    4. Voice excitation function to enhance voice articulation;

    5. Built-in compressor for automatic dynamic control;

    6. 4-band parameter equalizer to absorb 4 notching points;

    7. Automatic protection, automatic gaining and dynamic protection;

    8. 4-line line input (connected to computer and DVD) and 2-line recording level output;

    9. Constant resistance and constant output optional (2×100W constant resistance output, 120W constant voltage output);

    10. Microphone volume/music volume and machine parameter value adjustment and remote computer control

    (computer software control free of charge);

    11. Locked panel keys to prevent students’ accidental operation.
