AXIS 243SA - Audio
The noise canceller threshold value can be set to High, Medium High, Medium low and
Low. A lower threshold allows most of the audio to pass. Only the weakest background
noise is reduced. A higher threshold makes the noise canceller act on even stronger
background noise. At the maximum level High, there is a risk of reducing useful audio as
well.
There is a trade-off between noise cancelling and
sound quality. In other words, increasing
the noise canceller attenuation deteriorates sound quality. Adjust the threshold and the
attenuation to an optimum level by listening and changing the levels.
