Select the Tab “Advanced” (step 4)
Ensure that Sample rate is set to: 2 Channel 16 bit 48000 Hz (step 5)
3.2.15 Press tab “Levels” (Step 6. Select)
Adjust the Line or Microphone levels as follows:
a) If the Device is shown as “Line Properties” the Line level should default to “100” to
ensure sufficient drive. Adjust to setting “100” if required.
b) If the Device is shown as “Microphone Properties” the level value (7) needs to be set
between 3 and 5, (typically 4) to prevent clipping of the sinewave.
If on certain Computers - a value of 4 is not shown e.g. the displayed number jumps from 3
to 5 then use the left and right arrow keys and count you way. You will find whilst only 5 is
shown both the setting for 4 and 5 are available.
You can monitor the Audio levels on the Audio Level meters, shown in 3.2.13.
The Audio level should approx 50% to 60% of the maximum level.
If no signals are seen make sure that the USB-Codec is not Muted (8.)
When all adjustments are complete press “OK” (step 9.) This closes the Properties screen.
Press “OK” on the Sound Setup Screen shown in 3.2.13 to close down this screen.
