Microphone amplification (gain)

You can use the GAIN controller to increase or decrease the input level in order to achieve a “clean input signal.” Depending on the strength of the incoming audio signal, the LED will be green or yellow.



Meaning of indicators

The indicators tell you when:
  • The signal is within the tolerance range and amplified without artifacts (green LED).
  • The signal exceeds the tolerance range and is thus overdriven (yellow LED). This can lead to unpleasant noise, whistling or crackle, and/or feedback during audio output.
Note that the LED will still be green even if the input level is too low (for example, if the voices are quiet or the microphone is too far away). Detailed information on signal processing can be found in chapter Audio signal processing.

Tips for achieving optimal sound

To achieve the best sound with the PROFILE, we recommend the following:
  1. Make your recordings in a quiet environment (e.g. a studio or a closed room where you are not subject to external noise).
  2. Align the microphone so that the recommended distance between the sound source and the microphone is maintained (see Positioning the microphone).
  3. Adjust the microphone gain so that the input level always remains within the tolerance range in all intended recording situations, as indicated by the green LED (see Adjusting the input level (gain)).
