Power Fuse
Should the amplifier fail to operate and the power
indicator fail to light up when the POWER
switch
is turned on, the probable cause is either a power
stoppage or a blown fuse. To check, remove the
AU-101's line cord from its a.c. outlet,
turn the
fuse holder on the rear panel counterclockwise.
and remove the fuse. If it is blown, replace it with
a new glass-tubed fuse of the same capacity (100~
L17V—2A, 220~240V—1.5A) after determining
and eliminating the trouble source that caused the
fuse to blow. Using wire or a fuse of a different
capacity as a stop-gap measure is dangerous and
should be avoided.
Voltage Adjustment
This plug has been set to the voltage of your area
prior to shipment. Ifthe amplifier is ever moved to
an area with another voltage requirement, this plug
must be changed to the proper voltage of the new
area. lo change, remove the cramp from the back
panel, remove the plug from the voltage socket you
nave been using, and plug the arrow head into the
appropriate voltage requirement of 100, 117, 220
or 240 volts.
Quick-Acting Fuses
If, after the POWER switch is turned on and the
power indica'or lights up, neither channel operates
_ or only one operates normally, is either because one
or both quick-acting fuses have blown. In this case,
remove the line cord from its a.c. outlet and remove
the bonnet from the chassis to check to see if the
fuses are blown. If the fuses are faulty, replace them
with identical 1.5A fuses (supplied) after finding and
eliminating the source of trouble that caused them
to blow. The trouble is probably by short at the
output circuit or excessive input fed into the input
circuit.
A.C, Outlets
The AU-101 is provided with two A.C. outlets on
its rear panel. One outlet (marked SWITCHED) is
switched on and off by the POWER switch on the
front panel.
Caution: The maximum capacity of this outlet is
OOVA, and the other (marked UNSWITCHED) is
1SO0VA. Never use either beyond their rated
capacity. The voltage supplied by the AC outlets
is the same as the power supply voltage used.
