Audio Note L2 Line Preamplifier Instruction Manual page 66

By measuring the AC voltage at the output of the Line Board you will see an AC signal coming through - You will want to
see a value of approximately 5mV at full volume - if you can adjust the volume control you should be able to see the audio
signal larger or smaller - you can also try moving the selector switch and seeing the signal disappear and then reappear
as you select.
Do this for both channels to assure a proper working Line Stage!
If you have wired anymore line level inputs then you may repeat the test for the other wired inputs (again using the CD
and test disc as described).
Congratulations you have completed the Line Stage testing – If you are having problems at this point check over your
wiring and or contact us at audionotekits@rogers.com to help you debug.
