ONKYO Car Speaker SKW-208 User Manual

En-

6

• 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.

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.

• The power plug is not fully inserted.

➞ Insert the power plug fully into the power outlet.

• 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.

• The sound source might not include a superbass range.

➞ Play a sound source that includes a superbass 

range.

• 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.
