ute: Both channel mute and fader are behind auto gain. If the channel
level is bigger, the level gain of other channels may also be reduced
even the channel mute is on.
Gain:
Gain fader adjustment may increase/decrease the volume
proportion in automix.
Priority: P
riority setting may give priority treatment to high priority
channels than low priority channels, and thus automix algorithm will be
affected. Priority parameter ranges from 0 to 10. The bigger the value,
the higher the priority.
Both channel mute and fader are behind auto gain. Any adjustment made towards these two
parameters won’t influence the operation of automix. For example, If the channel level is bigger,
the level gain of other channels may also be reduced even the channel mute is on. Channel mute
shall be turned on and automix shall be turned off to set signal mute and prevent its influence on
automix. Mute button at each channel shall be muted and directly connect output mute when mixing
sound. Channel faders also control sound mixing level and direct output level of channels. Click the
textbox and input a dB value to control channel level precisely.
Priority control allows high priority channels to cover low priority channels, and thus automix
algorithm will be affected. Priority value can be set from 0 (the lowest priority) to 10 (the highest
priority), and the default value is 5 (standard priority). Users may use slider or click textbook to input
a specified priority between 0 and 10 to adjust priority. Value increasing means priority increasing.
If two channels have the same signal level, then the channel with higher priority will get more auto
gain. If there is one-unit priority between them, then the channel with higher priority will get extra
sound mixing gain of 2dB (suppose the slope of the two channels is set at 2.0). For example, if channel
1 and 2’s priorities are respectively set at 6 and 3, and the input level of those two channels are the
same, then Channel a will get extra sound mixing gain of 66dB than Channel 2. During operation, it
shall be noted that the slope setting of main control parameters will also influence sound mixing gain
difference brought by the priority weight of channels. If the slope is set at 3.0, then one priority unit
difference will result in gain difference of 4dB. If all channels have the same priority, then their priority
settings shall be at 5.
Note: In some settings, users shall be very careful when using ultra priority differences between
channels, such as priority of 0 and 10. If channels with ultra high priority recognize signals like
