NOTE
: This page applies to the mic input only. It does not come into play for the STAxxx.
When the input signal is too high for the gain setting, it is clipped and results in distortion and popping. The limiter
is used to prevent clipping by beginning to engage around -10 dBFS. When using a microphone, normally you
would enable the limiter. However, if the input signal is coming from a mixer that is using a limiter, you should
disable this limiter.
Since it is implemented in the digital domain, the automatic limiter may engage even when you don‟t hear any
substantial audio. The purpose of the limiter is to prevent the mic preamp from over-driving the A/D converter,
so the limiter operates on audio before it has been processed by the highpass filter. If there is a massive amount
of low frequency audio content being filtered out, such as wind noise, you may hear the effects of the limiter
without hearing the audio that caused the limiter to engage. If this occurs, the gain is set too high and you must
reduce it to below the level that triggers the limiter.
