threshold will be directly raised by ratio. The target level is properly set so that the sound signal may be output
stably.
AGC control is to automatically control range of gain through changing I/O compression ratio. When the
weak signal is input, the signal will be amplified to ensure the strength of the sound signal output; when the signal
strength input reaches to the certain extent, the signal will be compressed to lower the range of output.
Input
: the level of input automatic gain controller.
Output
: the level of output automatic gain controller.
Threshold
: it is the initial level of automatic gain. When the signal is less than this limit value, the automatic
gain processing module will be enabled to gain the excessively small signal.
Bypass
: the signal input is bypassed and not be processed.
3.5.6 Auto Mixer
Automatic mixer adjust gain from each input channel in real-time to adapt the general level, through
improving the high signal gain, reducing low level signal gain to maintain the overall system gain.
Each channel of automatic mixer has input, gain level meter and an automatic gain, channel fader, priority, and
channel muting.
Channel control: each channel has an automatic" AUTO " button, turn on the channel into the automatic mixing. If
you need a background music channel at a fixed level, or need to be a "chairman" Mic always remains in the open
state, then you need to push the “AUTO” off button on the automatically key. When a channel to select" AUTO "
