ONKYO HTP-938 プリント

The Home Theater means that you can enjoy surround sound with a real sense of movement in your own home — just like being in 
a movie theater or concert hall.

ab Front left and right speakers (SKF-980) 

They should be positioned facing the listener at about ear level, and equally 
spaced from the TV. Angle them inward slightly so as to create a triangle, with 
the listener at the apex.

c

Center speaker (SKC-980) 
Position it close to your TV (preferably on top) facing forward at about ear 
level, or at the same height as the front left and right speakers.

de Surround left and right speakers (SKR-980) 

Position them at the sides of the listener, or slightly behind, about 60 to 100 cm 
above ear level. Ideally they should be equally spaced from the listener.

f

Subwoofer (SKW-938) 
The subwoofer handles the bass sounds of the LFE (Low-Frequency Effects) 
channel. The volume and quality of the bass output from your subwoofer will 
depend on its position, the shape of your listening room, and your listening 
position. In general, a good bass sound can be obtained by installing the sub-
woofer in a front corner, or at one-third the way along the front wall, as shown.

Read the following before connecting your 
speakers:
• Turn off your receiver before making any 

connections.

• Pay close attention to speaker 

wiring polarity. Connect positive 
(+) terminals to only positive (+) 
terminals, and negative (–) ter-
minals to only negative (–) terminals. If the 
speakers are wired incorrectly, the sound 
will be out of phase and will sound unnatu-
ral.

• Be careful not to short the positive and nega-

tive wires. Doing so may damage your amp.

• When you connect the surround back and front 

high speakers, prepare for it separately.

• The front grille is not designed to be removed so does not attempt 

to remove it forcibly, as this will damage it.

• The Auto Standby function turns the subwoofer on when the input signal 

exceeds a certain level. If the Auto Standby function does not work reli-
ably, try slightly increasing or decreasing the subwoofer output level on 
your receiver.

• If the Standby/On indicator lights (both red and blue LEDs) several sec-

onds or minutes after the sound output stopped, this means that the amp 
protection circuit has been activated. In this case, set the OUTPUT LEVEL 
control 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.

Make sure the SKW-938 subwoofer’s output 
level control is set at the “THX-POSITION”.
You can then adjust the level as needed.

Standby/On indicator
Red: Subwoofer in standby mode
Blue: Subwoofer on
With the Auto Standby function, the 
SKW-938 automatically turns on when 
an input signal is detected in Standby 
mode. When there’s no input signal for 
a while, the SKW-938 automatically 
enters Standby mode.

OUTPUT LEVEL control
This control is used to adjust the vol-
ume of the subwoofer.

LINE INPUT
This RCA input should be connected to 
the subwoofer pre out on your AV 
receiver with supplied RCA cable.

POWER switch
Press this switch to the ON position to 
turn on the power. Press it to the OFF 
position to turn off the power.

To mount the front/surround speakers vertically, use 
the keyhole slot shown to hang each speaker on a 
screw that’s securely screwed into the wall.

To mount the center speaker horizontally, use the two 
keyhole slots shown to hang each speaker on two 
screws that are securely screwed into the wall.

• A mounting screw’s ability to support a speaker 

depends on how well it’s anchored to the wall. If you 
have hollow walls, screw each mounting screw into a 
stud. If there are no studs, or the walls are solid, use 
suitable wall anchors. Use screws with a head diameter 
of 9 mm or less and a shank diameter of 4 mm or less. 
With hollow walls, use a cable/pipe detector to check 
for any power cables or water pipes before making any 
holes. 

• Leave a gap of between 5 mm and 10 mm between the wall and the base 

of the screw head, as shown. (We recommend that you consult a home 
installation professional.)

We recommend using the supplied cork spacers to achieve the best possible 
sound from your speakers. The cork spacers prevent the speakers from mov-
ing, providing a more stable platform.

■

The front, center and surround 
speakers have detachable grilles. 
See the right illustrations to attach 
or detach them.
