A conventional, 15-ampere IEC standard power cord is used with the SC-2. A
high-quality AC mains cord is included with the product, although the use of the
standardized IEC receptacle means that you may easily substitute another high-
quality AC mains cord if you wish.
WARNING! Your new Wisdom Audio SC-2 has been safety-tested and is designed
for operation with a three-conductor power cord. Do not defeat the “third pin” or
earth ground of the AC power cord.
An AC mains switch is located above the power cord on the rear panel of the SC-2.
This switch may be used to disconnect the unit from the AC mains without having
to actually unplug the SC-2 from the wall outlet.
If you plan to be away for an extended period or have any other reason to turn the
SC-2 completely off, you may either unplug the SC-2 or you may use the
AC mains
switch .
DANGER! Potentially dangerous voltages and current capabilities exist within your
SC-2. Do not attempt to open any portion of the SC-2’s cabinet. There are no
user-serviceable parts inside your SC-2. All service of this product must be referred
to a qualified Wisdom Audio dealer or distributor.
We recommend that care be taken to ensure that all AC plugs for the equipment in
the system be wired so as to ensure proper AC polarity. Doing so will minimize
noise in the system.
In the U.S., a simple AC mains tester (found at any hardware store) can test to
ensure that your electrical outlets are wired properly. Elsewhere in the world (for
example, in European Union countries), the AC mains plugs themselves are not
always polarized. Your dealer can test for the proper orientation of the plug in the
outlet. In such a case, it is good practice to mark both plug and outlet to ensure
that all products remain in the proper orientation should it become necessary to
temporarily disconnect the system (as for example, during an electrical storm).
Finally, the Wisdom Audio SC-2 incorporates a fuse block that protects both the
live and neutral (ground) sides of the circuit. If your SC-2 is plugged into an AC
outlet that you know is live (plug a lamp into it as a test), and yet appears to be off,
check the following:
a.
Check the AC cord to make sure it is not damaged.
b. Check the AC mains switch to ensure that it is On (the side with the straight
line is depressed, not the “O” side).
c. If that does not resolve the problem, turn Off the AC mains switch (“O”) and
then disconnect the power cord from the AC mains receptacle.
d. Using a small screwdriver, gently pry open the fuse block cover at the top
