    MC7100 Digital Frequency Shifting Amplifier

    The MC7100 composite digital amplifier for teaching is a complete set of professional amplification device specially designed

    for school classroom and also meets amplification requirements in courts, government authorities, army, enterprises and

    government-supported organizations. Regarding particularity of medium and small-sized public sites, the device solves three

    difficulties such as amplification stability, sensitivity and amplification articulation, effectively inhibits acoustic feedback,

    significantly weakens microphone whistling and ensures prime amplification.

    Function features

    1. 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 inputs, MIC1-MIC4 with phantom power supply. (MIC1~4 1/4)

    4. Voice excitation function to enhance voice articulation.

    5. Built-in compressor, automatic dynamic control.

    6. 4-band parameter values balance to absorb 4 notching points.

    7. Automatic protection, automatic gaining, and dynamic protection.

    8. 4-channel input (connected to computer, DVD etc.) and 2-channel recording electric level output.

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

    10. Microphone volume/music volume and machine parameter numerical adjustment and remotely controlled by computers

    (computer software control available for free).

    11. Panel keys locked to prevent students’ accidental operation
