About Auto Shut Off
The Reference 80S auto shut-off feature is
designed to turn the amplifier off after two
hours of no signal being present at the
output of the amplifier.
In the event that quiet music is listened
to at very low volumes, there may not
be adequate signal for the auto shut off
circuit, resulting in the amplifier turning
itself off. If this is the case, please
disengage the auto shut off feature.
The auto shut off feature control switch
is located on the back panel of the
Reference 80S.
Note
The auto shut off feature is not in the
signal path of the amplifier and has
no deleterious sonic effect on music
playback.
