Configuration of the rubber stoppers may be different from the figure, such as being 2 sheets instead of 1 sheet, but the total number will be same.

We recommend using the supplied rubber stoppers to achieve 
the best possible sound from your speakers. 
The rubber stoppers prevent the speakers from moving, 
providing a more stable platform.

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

• 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.

• 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 seconds, and then 
reconnect the power cord. If that doesn’t solve the issue, contact your Onkyo dealer.

To set the level of the subwoofer, use the OUTPUT LEVEL 
control. Set it so that bass sounds are evenly balanced with the 
treble sounds from the other speakers. Because our ears are less 
sensitive to very low bass sounds, there’s a temptation to set the 
level of the subwoofer too high. As a rule of thumb, set the 
subwoofer level to what you think is the optimal level, and then back it off 
slightly.

If the subwoofer is placed on a hard floor 
(wood, vinyl, tile, etc.) and playback is very 
loud, the subwoofer’s feet may damage the 
flooring. To prevent this, place the supplied 
pads underneath the subwoofer’s feet. The pads 
also provide a stable base for the subwoofer.

With the Auto Standby function, the SKW-780 
automatically turns on when an input signal is 
detected in Standby mode. When there’s no input 
signal for a while, the SKW-780 automatically enters 
Standby mode.

OUTPUT LEVEL control
This control is used to adjust the volume of 
the subwoofer.
LINE INPUT
This RCA input should be connected to the 
subwoofer pre out on your AV receiver with 
supplied RCA cable.

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.

Center speaker (SKC-690) 

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.

Front left and right speakers (SKF-690) 

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.

Surround left and right speakers (SKR-690) 

Position them at the sides of the listener, or 
slightly behind, about 2 to 3 feet (60 to 
100 cm) above ear level. Ideally they should be 
equally spaced from the listener.

Subwoofer (SKW-780) 

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 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 (–) 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.

Specifications and appearance are subject to change without 
prior notice.

For non-magnetic shielded 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.
