Caution!
IMPORTANT SAFETY INSTRUCTIONS
Caution
To reduce the risk of electric shock, do not remove cover (or back). No user-serviceable parts inside. Refer
servicing to qualified service personnel.
The lightning flash with arrowhead symbol is intended to alert the user to the presence of uninsulated
“dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk
o
f electric shock to persons.
The exclamation point symbol is intended to alert the user to the presence of important operating and
maintenance (servicing) instructions in the literature accompanying the subwoofer.
1. Read Instructions — All safety and operating instructions should be read before the product is operated.
2. Retain Instructions — The safety and operating instructions should be retained for future reference.
3. Heed Warnings — All warnings on the product and in the operating instructions should be
adhered to.
4. Follow Instructions — All operating and use instructions should be followed.
5. Water and Moisture — The product should not be used near water — for example, near a bathtub,
washbowl, kitchen sink, laundry tub, in a wet basement, near a swimming pool or the like.
6. Carts and Stands — The product should be used only with a cart or stand recommended by
the manufacturer.
7. Wall or Ceiling Mounting — The product should be mounted to a wall or ceiling only as recommended
by the manufacturer.
8. Ventilation — The product should be situated so that its location or position does not interfere with its
proper ventilation. For example, the product should not be situated on a bed, sofa, rug, or similar surface
that may block the ventilation openings; or placed in a built-in installation such as a bookcase or cabinet
that may impede the flow of air through the ventilation openings.
9. Heat — The product should be situated away from heat sources such as radiators, heat registers,
stoves, or other products that produce heat.
10. Power Sources — The product should be connected to a power supply only of the type described in
the operating instructions or as marked on the product.
11. Grounding or Polarization — This product may be equipped with a polarized alternating-current line plug
(a plug having one blade wider than the other). This plug will fit into the power outlet only one way.
This is a safety feature. If you are unable to insert the plug fully into the outlet, try reversing the plug.
If the plug should still fail to fit, contact your electrician to replace your obsolete outlet. Do not defeat
the safety purpose of the polarized plug.
12. Power-Cord Protection — Power-supply cords should be routed so that they are not likely to be walked
on or pinched by items placed upon or against them, paying particular attention to cords at plugs,
convenience receptacles, and the point at which they exit from the product.
13. Cleaning — The product should be cleaned only as recommended by the manufacturer.
14. Nonuse Periods — The power cord of the product should be unplugged from the outlet when left unused
for a long period of time.
15. Object and Liquid Entry — Care should be taken so that objects do not fall and liquids are not spilled
onto the enclosure.
16. Damage Requiring Service — The product should be serviced by qualified service personnel when:
a. The power-supply cord or plug has been damaged.
b. Objects have fallen or liquid has been spilled into the product.
c. The product has been exposed to rain.
d. The product does not appear to operate normally or exhibits a marked change in performance.
e. The product has been dropped or damaged.
17. Servicing — The user should not attempt to service the product beyond what is described in the
operating instructions. All other servicing should be referred to qualified service personnel.
18. Lightning — For added protection for the product during a lightning storm or when it is left unattended
and unused for long periods of time, unplug it from the wall outlet.
19. Overloading — Do not overload wall outlets, extension cords or integral convenience receptacles as this
can result in a risk of fire or electric shock.
20. Attachments — Only use attachments and accessories specified by the manufacturer.
21. Voltage — Insure that the subwoofer is only connected to the rated source voltage. Do not connect the
120-volt version to 230-volts or vice-versa. This will result in damage to the subwoofer and possible
injury to the user.
CAUTION: To prevent electrical shock, match wide blade of plug to wide slot, fully inserted.

6) LED Numeric Indicator
This LED supplies information on volume, crossover, woofer type, and other information. The
l
ight button on the remote deactivates this display. Upon startup, the display shows the
model of subwoofer the SC-602 amp is set to, then reverts to the volume indicator.
(7) Volume Control
These buttons allow you to balance the output from the subwoofer with the output of the
main speakers in your system. The volume should be set to achieve similar volume level of
both the main speakers and subwoofer. The default volume is 30.
Note: Volume can also be controlled by using the supplied remote.
WARNING: Some manufacturers preset their receivers with the Sub-Out (A.K.A. LFE)
channel signal at a minimum level. It is very important to verify that your receiver Sub-Out
channel is set to the same output level as your front right and left channels. Refer to your
receiver manual for the individual channel level adjustment procedure. If your receiver
Sub-Out channel is set too low, the subwoofer may appear to have a weak output, it may
sound noisy or distorted, and the Auto On/Off feature may not operate properly.
(8) Optional Rack Mount Ears (Included)
These ears can be attached to the SC-602 amp to allow standard 19” rack mounting.
REAR PANEL CONNECTIONS
Following are brief descriptions described in Figure 2. More detail on these controls can be
found in the next section.

(9) Thru Jacks
These RCA connectors are for passing along the same signal that goes into your subwoofer
to a second “daisy-chained” system. The signal fr
the input signal.
om these RCA connectors is the same as
(10) Line Input / LFE Input
Connect these jacks to the LINE OUT pr
of your receiver/processor. If using the LFE output from your receiver or processor, plug
the single cable into the jack labeled LFE input or, for more signal, use a “Y” connector
(optional) and feed the signal into both “R” and “L” inputs. Examples of these types of
connections can be found in Figures 2A and 2B.
