The AUDIS-03M module is a digital acoustic monitor with a built in loudspeaker and two audio modes. In PITCH mode the voltage input signal is converted to a tone and in NOISE mode the signal is highpass filtered to monitor the noise.
The AUDIS-03M is equipped with a THRESHOLD potentiometer for setting a monitor threshold. Only signals are monitored, whose amplitude exceeds the THRESHOLD. Therefore, the THRESHOLD can be used for masking the noise of the baseline.
