Use the A and V keys to change the sensitivity.
For example, the display will show:
Switch between the source you are changing and the
reference source until they sound equally loud.
Repeat the procedure for your other sources.
When you have finished programming levels, switch the
power off and on again to restore the integrated amplifier to
normal operation.
If you know the output level of your sources you can probably
set the gains by calculation. The following table shows the
correspondence between the gain and sensitivity on the
12dB
standard audio inputs and on the LP inputs:
