4.1.2 Parameter information:
(1) Main control parameter
On and Off: Turn on or off the mixing function. The effect of turning off the mixing function is the
same as the Line out output of the three-generation conference server, that is, the direct
Gain: The overall output gain of the automixer. Control the volume level of the mix output.
Slope: Similar to the extension ratio of the extender, the larger the slope value is, the more the
sound transmission gain is obtained by the speaking microphone, the more the sound transmission
gain is attenuated by the non-speaking microphone, and the smaller the slope value is, the less the
speaking microphone obtains the sound transmission gain. Other non-speaking microphones have
less attenuation, but at the same time the more the total attenuation. A common setting is 2 or
approximately 2; if set to 1.0, the effect is equivalent to turning off automix for all channels; when
set it to 3.0, it will cause a larger gain adjustment, possibly produce unnatural effects. The higher
the value, the more channels are opened, and the more the total attenuation is.
Response Time: The time to obtain full transmission gain when a microphone is speaking or the
time to decay the microphone gain of other microphones that are not speaking. The longer the time
is set, the longer the time for the speaking microphone to obtain all the sound transmission gain,
and the longer the time for other non-speaking microphones to attenuate the sound transmission
gain. And vice versa. Therefore, if the time is set too short, it will cause the sound to be unnatural,
and if it is too long, the prefix may be swallowed.
Ambient Threshold: The threshold of ambient noise received by the microphone. When multiple
microphones are turned on, only one microphone is speaking, and this microphone cannot get most
of the gain, because other microphones that are not speaking at this time are distributed with a
certain percentage of gain due to the ambient sound, and the more microphones are turned on, the
ratio bigger. The purpose of this parameter is to identify which microphones are speaking, and the
speaking microphone will get most of the gain regardless of the number of microphones on.
Mute: Turn mute on or off. Control the mute function of the mix output.
On and Off: Turn on or off the mixing function. The effect of turning off the mixing function is the
same as the Line out output of the three-generation conference server, that is, the direct
Gain: The overall output gain of the automixer. Control the volume level of the mix output.
Hold Time: You can adjust the length of time the channel remains open after the microphone stops
speaking. Make sure that short pauses between words and phrases when the speaker is speaking
does not cause the channel to close. If this parameter is set too short, it will cause the sound to
fluctuate loudly. The gate auto mixing supports preemption. For example, when the number of
