MC783 8-channel smart conference mixer
The mixer offers 8 channels of microphone input and additional 1 channel of AUX input. Action level for sound gate
is automatically adjusted and the channel with signal input only is automatically enabled.
Each channel can be configured as priority speech. In the process of speech in priority, speeches from other channels
will be attenuated automatically and the automatic attenuation is set at 20dB, 40dB or finely tuned.
The external control is used to force enabling or disenabling of microphone directly without internal control switch of
the mixer to cut off unnecessary microphone input.
NOMA function: the NOMA (Number of open Microphone Attenuated) function is used to adjust output level automatically
with increased channels used. With expanded use of multiple mixers, sound whistling can be avoided with increased gain
of the system.
The external control output terminal of control voltage is configured to control external signal lamps or cameras.
The manual mode function is selected and automatic mixing is set as general mixer.
Switches and VR on the internal base plate are used for performance parameter setting to achieve ideal operation.
