Using the Rubber Stoppers for a More Stable Platform
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.

STANDBY/ON indicator
Red: Subwoofer in standby mode
Blue: Subwoofer on
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
This control is used to adjust the volume of the
subwoofer.
To AC outlet
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 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.
LINE INPUT
This RCA input should be connected to the
subwoofer pre out on your AV receiver with
supplied RCA cable.
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.

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.

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.

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

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.

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.
