Advanced use
1.
Using the MAIN MIX LEVEL knob and the volume controls of your amp or speakers, adjust
the volume of the sound from the speakers so it’s at a suitable level.
Adjust the volume as you would for normal playback when listening to the music.
If the speaker volume is too high the test signal will be produced at a loud volume, and if the volume is too
low the sensor will be unable to detect the test signal. Either situation will prevent the automatic adjustment
from occurring correctly.
