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-2.1 is turned on, you do
not hear loud unwanted sounds.

preamplifier.
Select the proper input on the control amplifier or
