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 (connected to the TA-5M) 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.
