off the automatically key, the gain will be automatically regulated, the channel signal level will not affect the other
channel gain ( such as no longer
affects automatic mixer gain calculation ).
Channel mute and fader are automatic gain type, i.e., no matter how you act; there is no effect on automatic mixer.
It means that a particular channel is silent, if the high level signal on the channel is present, the remaining
channels’ level would also reduce. In order to mute a signal and prevent the signal effect automatic mixing, please
open the mute and turn “AUTO” off
automatic mixer. Each channel of the mute function is to mute the channel in mix and mute the output channel
directly.
Channel fader control the channel mix level and output level directly.
Priority control PR: allows the priority level high channel exceeding level of low passage, thus affecting the
automatic audio mixing algorithm.
The control grades from number 0 (lowest priority) to 10 (highest priority) the numerical definition of priority, the
default value is 5 (standard priority). User can control priority through the slider, also click on the edit box and
enter the number between 0 - 10 data adjusting priority. If the 2 channels are receiving a signal having the same
level, high priority channel will be a higher gain. Channels between each difference of 1 priority" units", the gain
will differ 2dB ( if Slope is set in 2 ).
For example, in channel 1's priority is set to 6, channel 2 priority is set to 3, when the two channel receiving the
same level signal, channel 1 is 26dB more gain than channel 2. Obviously, the slope setting affects the priority
weights. When Slope is set to 3.0, difference between each channel is 1 priority" units", the gain will differ 3dB.
If all channels of equal priority, please set all channel priority to 5.
Note: when the channel priority differences for extreme cases, such as 1 and 10, must be more circumspect. High
priority from the speaker up to very large signal, background noise, will" masking" out the low priority channel,
even when it is not in use, higher slope value will further exacerbate the problem.

AFC : select input channel which need the AFC processed, then choose output channel in the mixer.
AEC : select input channel which need the AEC processed, then choose output channel in the mixer.
LOCAL: local MIC output, which requires signal echo processing
Remote: reference signal
ANC : select input channel which need the ANS processed, then choose output channel in the mixer.
