Operations
To listen to music or view your favorite movies, follow
the operations below.
The procedures given below assume that the other
system components are already connected. (For
example, that the source components are already
connected to the control amplifier or the preamplifier.)
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-30.1 is turned on, you do not hear loud
unwanted sounds.
Turn on the ADM-30.1 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 or preamplifier.
Now all that remains is to control the control
amplifier or preamplifier and the other connected
system components to enjoy your music or
movies.
