Unpacking the SC-3
Please exercise caution when unpacking your new Wisdom Audio SC-3 to ensure
that you do not strain yourself.
CAUTION:
Do not attempt to lift your SC-3 while bending or twisting from the waist. Use your
legs for lifting, not your back.
Always stand as straight as possible and keep the SC-3 close to your body to reduce
strain on your back.
After unpacking your SC-3, keep all packing materials for future transport. In the
event that you need to ship your SC-3, only the original, purpose-designed shipping
carton is acceptable. Any other method of shipping this product runs a significant
risk of damage to the SC-3; damage that would not be covered by the warranty.
Carefully inspect your SC-3 for possible damage due to shipping. If you discover
any, contact your Wisdom Audio dealer immediately.

Placement Considerations
PRECAUTION
For your protection, review “Important Safety Instructions” and “Operating Voltage”
before you install your SC-3.
Note that adequate clearance for the AC cord and connecting signal cables must be
left behind your SC-3. We suggest leaving at least six inches (15 cm) of free space
behind your SC-3 so all cables have sufficient room to bend without crimping or
undue strain.
If possible, the SC-3 should also be placed in such a way that the power switch on
the rear panel is easily accessible. This switch disconnects power from the unit
completely, resulting in effective disconnection of the SC-3 from the AC mains. You
might think of this as a “vacation switch”, should you wish to turn off your system
completely when you will be away from home for a prolonged period of time. Just
remember to turn it back on again when you return.
Ventilation
Your Wisdom Audio SC-3 contains many active devices and a great deal of signal
processing. It will run quite warm under normal operation. It should not be placed
directly on top of another component that generates significant heat, such as most
power amplifiers. Do not block the vents on the sides of the unit.
Mechanical drawings are included in this manual to facilitate special installations
where necessary (see “Dimensions” at the end of this manual).

Special Design Features
Advanced Room Correction:Dirac®Room Calibration reduces sound quality
loss due to the listening room and improves the audio performance of your
speakers, thereby providing powerful sound quality improvement. You will
experience improved clarity, tighter bass and a more natural sound. This
sophisticated algorithm brings out the full potential of audio systems.
Multiple Setup Memories: We then went further and provided support for recalling
up to four complete and independent setup calibrations, any of which can be
selected as needed. While a single setup is all that is usually necessary, having the
ability to recall any of multiple setups can solve some otherwise difficult situations.
For example, you might want to have selectable setups for
1. different room conditions (e.g., drapes open vs. closed)
2. slightly different target curves (e.g., music vs. gaming)
3. various seating arrangements
Only you and your dealer can decide whether you would benefit from taking
advantage of any of these possibilities. Most people obtain everything they need
from a single setup; but having the flexibility to address unusual circumstances can
be invaluable.
Bi- or Tri-amplification: People who have wanted to extract the highest
performance from their systems have known for a long time that driving each
section of the speaker directly and separately yields the finest results. Of course,
this requires having a dedicated, active crossover to divide the frequency range
appropriately before the power amplifiers, so that they can then drive the speakers
directly.
Bi-amplification makes use of two channels of amplification to drive different
portions of a single channel.
The most common instance of “bi-amping” today is in home theater applications,
wherein a dedicated subwoofer handles the deepest

Special Design Features (Continued)
bass, while the remaining audible range is handled by the various front and
surround speakers. But you can also bi-amplify a full range loudspeaker, driving the
woofer separately from the drivers that handle the midrange and treble frequencies.
Logically, you can combine these two approaches, and the result is “tri-
amplification.” A “tri-amped” system uses separate amplification for three audible
ranges. In our case, the three ranges are:
•deepest bass (one or more subwoofers)
•mid-bass (the woofers in the front and surround speakers)
•midrange and treble (the planar magnetic panels)
Since each channel of the amplifier is delivering current into its load only over a
limited range of frequencies, several forms of distortion are reduced as compared to
each channel handling the full range of musical information.
The SC-3 supports up to 16 channels of inputs (all of which could be bi-amplified),
and 32 output channels all with Dirac, and also their own independent user EQ and
channel delay.
System-Specific EQ: Wisdom Audio speakers deliver extraordinary performance
from slim, elegant enclosures. However, we cannot cheat the rules of physics.
Delivering powerful bass from such small enclosures places unusual demands on
both the woofers and the amplifiers used to drive them.
Specifically, equalization is used to compensate for the unusually small enclosure
volume behind the woofer. This approach is used in almost all dedicated
subwoofers today, and we use it in our full range speakers. Doing so allows us to
achieve the bass performance usually associated much larger speakers, but in
elegant enclosures that support modern lifestyle choices.
