LINE INPUT
This RCA input should be connected to the subwoofer pre out on your AV receiver with supplied RCA cable.
Caution
•With other audio-video components, connect the subwoofer’s LINE INPUT to the subwoofer pre out jack of your equipment. Never plug any kind of musical instrument to the subwoofer.
Note
•The Auto Standby function turns the subwoofer on when the input signal exceeds a certain level. If the Auto Standby function does not work reliably, try slightly increasing or decreasing the subwoofer output level on your receiver. When there’s no input signal for a while, the SKW-980/SKW- 938 automatically enters Standby mode.
•If the Standby/On indicator lights (both red and blue LEDs) several seconds 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 minutes, and then reconnect the power cord. If that doesn’t solve the issue, contact your Onkyo dealer.
Before Using the Home Theater
Speaker Package
Using the Cork Stoppers for a More Stable Platform
We recommend using the supplied cork stoppers to achieve the best possible sound from your speakers. The cork stoppers prevent the speakers from moving, providing a more stable platform.

Setting the Subwoofer Level
Make sure the SKW-980/SKW-938 subwoofer’s output level control is set at the “THX POSITION”.
You can then adjust the level as needed.
Wall Mounting
To mount the front/surround/surround back speakers vertically, use the keyhole slot shown to hang each speaker on a screw that’s securely screwed into the wall.

Caution
• 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 (5/16") or less and a shank diameter of 4 mm (1/8") 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 (3/16") and 10 mm (7/16") between the wall and the base of the screw head, as shown. (We recommend that you consult a home installation professional.)
Enjoying Home Theater
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.

1Front 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.
2Center speaker (SKC-980)
Position it close to your TV facing forward at about ear level, or at the same height as the front left and right speakers.
3Surround left and right speakers (SKR-980)
Position them at the sides of the listener, or slightly behind, about 60 to 100 cm (2 to 3 feet) above ear level. Ideally they should be equally spaced from the listener.
4Surround back left and right speakers (SKB-980: HTP-993THX/SKS-HT993THX only)
These speakers further enhance the realism of surround sound and improve sound localization behind the listener.
Position them behind the listener about 60 to 100 cm (2 to 3 feet) above ear level.
5Subwoofer (SKW-980: North American and Asian models/SKW-938: European models)
The subwoofer handles the bass sounds of the LFE (Low-Frequency Effects) channel and bass from the satellite speakers when a crossover is specified. 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 subwoofer in a front corner, or at onethird the way along the front wall, as shown.
Connecting the Speakers
Speaker Connection Precautions
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 (–) terminals to only negative (–) terminals. If the speakers are wired incorrectly, the sound will be out of phase and will sound unnatural.
•Be careful not to short the positive and negative wires. Doing so may damage your amp.
Note
•When you connect the front high left and right speakers, prepare for it separately, or use the surround back left and right speakers.

Use with a TV set
In general, Braun tubes used for color television sets, etc. are extremely sensitive and can be affected even by the magnetism of the earth. If a speaker system is used near them, therefore, discoloring or distortion of pictures will occur.
For magnetic shielded speakers (Front speakers, Center speaker):
The speakers are shielded to prevent discoloration. In some situations, however, discoloration may still be an issue, in which case you should turn off your TV or monitor, wait 15 to 30 minutes, and then turn it back on again. This normally activates the degaussing function, which neutralizes the magnetic field, thereby removing any discoloration effects. If discoloration problems persist, try moving the speakers away from your TV or monitor.
For non-magnetic shielded speakers (Powered subwoofer, Surround speakers, Surround back speakers):
Try moving the speakers away from your TV or monitor. If discoloration should occur, turn off your TV or monitor, wait 15 to 30 minutes, and then turn it back on again. This normally activates the degaussing function, which neutralizes the magnetic field, thereby removing any discoloration effects.
