AXIS 210/210A/211/211A - Audio (AXIS 210A/211A only) 27

There are two adjustable parameters available for noise cancellation:

Noise canceller threshold level

Noise canceller attenuation

When the incoming sound is louder than the threshold it will pass without being affected. When lower than the threshold, the incoming sound will be reduced by a certain attenuation factor. The threshold level should be set higher than the background noise, but lower than the useful audio.

The noise canceller threshold value can be set to High, Medium High, Medium low or Low. A lower threshold will allow most audio to pass, only the weakest background noise will be reduced. A higher threshold will make 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 thus always a trade-off between noise canceling and sound quality. In other words, increasing the noise canceller attenuation results in deterioration in sound quality. To adjust the threshold and attenuation to an optimum level, change the levels and then listen to the result, repeating as necessary.
