Auto Shut Off
The Reference 160S is equipped with an auto shut-off feature, 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 160S.
Note:
The auto shut off feature is not in the signal path of the amplifier and has no deleterious
sonic effect on music playback.
