note:  The Main Power Switch needs to be in the on 
position before this switch is active.

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 detected (turning the power indicator red).

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 indica-
tor light stays green).

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. Avoid obstructing air flow to the back.
