Software interface
Bypass - enables and disables priority module. This function can't recover disa-
bled inputs in matrix module even if bypass is set in priority module. In order to
make occupied inputs active in matrix module, occupied inputs level must be
set to -72 dB manually.
Max. gain selector – designed to set maximum audio level increase in ANC
module when background noise level is very high.
Min. gain selector – designed to set lowest audio level decrease in ANC module
when background noise level is very low. It's default audio level.
Ratio – this parameter describes how much sound will be increased then ANC
module starts adjusting volume.
Speed - it's a time period in which ANC module increase or reduce audio level.
Higher level will makes audio level adjustment smoother and less noticeable.
Highly recommended set lowest level in order to notice sound level changes
more quickly during ANC configuration.

Gap threshold – ANC module starts ignore Gap timing and starts measure
and adjust output volume continuously when OCTO input level is lower than
Gap threshold. If output signal became higher than set in Gap thresholds, ANC
module makes noise measurements according to Gap timing settings – Mutes
audio signal in order to measure background noise.
Gap time – determinates how long the audio signal will be muted. ANC mod-
ule mutes audio for specified time in order to measure the background noise. It
helps to ensure that background music and public announcement will not be
measured as noise.
Monitor gap – it's a time period between the gaps.
Standard level - designed to set background noise value from which ANC
module will starts adjust audio level.
Output selector - designed to select OCTO outputs to which signal from priority
ANC module will be linked.
