    MC9172-1 Chairman Unit / MC9172-2 Delegate Unit:

    Full metal casting base is elegant and exquisite, ultra-long service life and noise-free touch switch.

    Built-in Hi-Fi condenser sound head reproduces sound better, high articulation and low noise,

    Efficient whistling inhibition function and powerful sound pickup effects.

    Sound head red operating indicator light is illuminating when the microphone is enabled.

    The chairman unit is installed with priority speech switch, which can switch off all delegate units when needed.

    The unit is completed with 2m+3 “T”-shaped 8-core aluminum foil shielded connecting wire to lower interference on wires by electromagnetic wave.
