12 rubber stoppers* (For Front/Surround speakers)

4 rubber stoppers

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.

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.

• 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 acti-

vated. In this case, set the OUTPUT LEVEL control to the center position, and discon-

nect 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.

Setting the Subwoofer Level

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.

Using the Floor Pads for Subwoofer

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-501E

automatically turns on when an input signal is

detected in Standby mode. When there’s no input

signal for a while, the SKW-501E automatically

enters Standby mode.

Press this switch to the ON position to turn on the

power. Press it to the OFF position to turn off the

power.

OUTPUT LEVEL control

Enjoying Home Cinema

The Home Cinema 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.

Connecting the Speakers

Corner

1/3 of wall

position

Center speaker (SKC-648)

Position it close to your TV (prefer-

ably 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-648)

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-648)

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.

Subwoofer (SKW-501E)

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.

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.

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

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.
