3.4.10 Spl
Noise gain compensator: automatically adjust output volume according to ambient noise
induction and processing.
Maximum gain: the maximum amount that can be adjusted.
Minimum gain: the minimum amount that can be adjusted.
Gain sensing ratio: the ratio of lifting or attenuation.
Speed: the speed of lifting or attenuation.
Trim： gain.
Noise threshold: greater than the starting gain, less than the reduction.
Distance: distance between reference and local signals
3.4.11 AutoMixer
In a conference room, if several microphones are opened to the same gain level and there is only one
person speaking, the microphone effect may be not clear. Other microphones will pick up noise and
reverb in the room. When these signals are mixed with normal microphone signals, audio output
quality will be greatly reduced and the whole amplifying system will easily get squealing, which will
result in sound transmission gain. To solve the issue, other unused microphones shall be closed.
Automixer may close them at a higher speed than manual operation.
There is a built-in gain share automixer inside the processor. It supports up to 32-channel audio signal
output. There is a direct output at each channel of auto mixing matrix, which is only influenced by
