ADJUSTING THE USB INPUT LEVEL + RECORDING CHANNELS IN WINDOWS:
In some cases you will have to adjust the input level for the USB-recording in Windows (see drawing below):
A. Input level too small: recording will have a poor signal/noise ratio.
B. Input level too high: recording will be distorted.
C. Input level is OK: well balanced recording.
In cases A and B you should adapt the recording level via Windows setup:
 In Windows, open the configuration window and select "SOUND"
 In the new window, select the "recording" tab
 Choose the USB audio device (mostly indicated as "microphone") and press the "properties" button.
 In the new window, select the "levels" tab  you can adapt the input level and press "apply" to confirm.
 Select the "advanced" tab  from the dropdown list, select "2channel, 16bit, 44100Hz (CD Quality)"
 Press the "OK" button to confirm and save.

 EQUALIZATION: 31-bands equalizer with a lot of presets.
