Customising the integrated amplifier

23

Use the

A and V keys to change the sensitivity.

For example, the display will show:

12dB

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

standard audio inputs and on the LP inputs:
