Adjustments
Crossover frequency and output level
• Adjust the SKW-208 output level and crossover fre-
quency to suit your listening room and connected
speakers.
• Be aware that you might set the subwoofer to a high
output level because superbass-range sound is less
audible than other sound ranges. To obtain well-bal-
anced frequency characteristics, set the output level
to a slightly lower level than seems optimal. (This
will also prevent the input of signals that are too
strong.)
Note:
Be careful not to allow the input of excessive power.
Input levels that greatly exceed normal situations can
damage the SKW-208. Also note that switching opera-
tions at the amplifier may generate excessive noise that
may result in damage. When using switches at the ampli-
fier, first lower the volume to prevent accidental damage.
Placement
The placement of the SKW-208 can greatly affect the
sound that is produced. In general, a good bass sound
can be obtained by installing the subwoofer in a front
corner, or at one-third the width of the wall, as shown.
Troubleshooting
The unit does not turn on
• The power plug is not fully inserted.
➞ Insert the power plug fully into the power outlet.
No sound is output
• The OUTPUT LEVEL knob is set to the MIN level.
➞ Set the OUTPUT LEVEL knob properly.
• Pin connector cable is not properly connected to the
LINE INPUT jack.
• The speaker setting at the amplifier (or receiver) is
incorrect.
➞ Check the settings at the amplifier (or receiver).
• The input signal is so small that the unit entered
Standby mode.
➞ Slightly increase the output level at the amplifier
(or receiver).
• If the STANDBY/ON indicator lights up (both red and
blue LEDs) several seconds or minutes after the sound
output stopped, this means that the amp protection cir-
cuit has been activated. In this case, set the OUTPUT
LEVEL knob to the center position, and disconnect
the power cord from the AC outlet. Wait at least 10
seconds, and then reconnect the power cord. If that
doesn’t solve the issue, contact your Onkyo dealer.
Low sound output
• The sound source might not include a superbass range.
➞ Play a sound source that includes a superbass
range.
Hum noise
• Pin connector plug is not inserted completely.
➞ Fully insert the pin connector plug.
• External leakage flux (induction noise by TV, etc.)
occurs.
➞ Relocate the SKW-208 away from the noise
source and re-connect.
