6. AC Mains Input & Switch (Continued)
SC-3 completely off, you may either unplug the SC-3 or you may use the AC mains
switch .
DANGER! Potentially dangerous voltages and current capabilities exist within your
SC-3. Do not attempt to open any portion of the SC-3’s cabinet. There are no user-
serviceable parts inside your SC-3. 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-3 incorporates a fuse block that protects both the live
and neutral (ground) sides of the circuit. If your SC-3 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
edge of the assembly. (You may be able to do it with just your fingernail.)
e.
Pull out the red fuse block, and check fuse. If blown, please contact your
local Wisdom Audio dealer (or Wisdom Audio) for service.
7. Outputs
These 32 balanced audio outputs carry the room-corrected full-range , high-pass , and
or low-pass portion of the audio spectrum and must be connected to the amplifiers
that drive the loudspeakers and or subwoofers.
