source components are already connected to the control
amplifier or the preamplifier.)
1
Lower the volume at the control amplifier or
preamplifier.
Lower the volume of the control amplifier or
preamplifier to the minimum so that when the
ADM-20.4 is turned on, you do not hear loud
unwanted sounds.
2
Turn on the ADM-20.4 and select the input on the
control amplifier or preamplifier.
Select the proper input on the control amplifier or
preamplifier.

Slowly increase the volume of the control amplifier
