Auto: When set to this position, the subwoofer’s auto-on
circuitry turns the amplifier on when an audio signal is
presented (turning the “power indicator” light green), and
turns it off in approximately 15 minutes if no signal is detect-
ed (turning the “power indicator” red).
Placement
Place the subwoofer next to a wall or in a corner near your main speakers. Typically, the sound is best when the
subwoofer is within 15 feet (4.5m) of the main speakers. However, the sharp 24dB/octave crossover roll-off permits
placement farther from the main speakers if necessary. Since the ear is unable to localize the low frequencies of the
subwoofer, the bass still appears to come from the main speakers. In most cases, the subwoofer may be placed
anywhere in the listening room.
The level of bass output from the subwoofer will vary at different positions in a room. When placed near walls, its
loudness is emphasized. Corner placement provides the most bass output, while placement near only one wall will
provide somewhat less bass. Placement completely away from walls may produce too little bass. Regardless of how
you place the subwoofer, you can adjust the subwoofer’s level with its volume control. If you move the subwoofer,
recheck the setting of the polarity switch. Use the setting that yields the louder and more dynamic sound.
IMPORTANT: Do not place the subwoofer where there is a chance of contact between the rear panel and drapes or
furniture.

in corner for maximum
bass output
On: When set to this position, the subwoofer’s auto-on
circuitry is bypassed and the amplifier will remain on
whether an audio signal is present or not (the “power
indicator” light stays green).

Note: The Main Power Switch needs to be in the “on” position before this switch is
