OPERATING CONTROLS
1. -3dB
switch:
This switch adjusts the overall contour of the sub¬
woofer's response. The
25 Hz
setting provides the
deepest bass extension and the most accurate
response. We recommend this setting for high accu¬
racy music systems. The 35 Hz setting provides
higher maximum loudness at the expense of some
bass extension. This will allow dramatic special
effects in movies to be played louder.
2. PHASE:
The phase switch compensates for placement differ¬
ences between the main speakers, the subwoofer
and your listening position. This switch affects the
relatively narrow range of notes where the main
speakers and the subwoofer "overlap." Adjust it for
maximum output in this narrow range (not for 'best
sound"). The affect this control has can be subtle.
3. LOW PASS:
Even though a subwoofer only produces "bass
notes," the upper end of its range should be tailored
to blend well with your main speakers. The sub¬
woofer should not produce any bass your main
speakers can produce. The LOW PASS control sets
this limit. The lowest setting (60 Hz) should be used
with large main speakers. Its middle settings should
be used with small floorstanding speakers or large
bookshelf speakers. Its highest setting should be
used with small speakers (see table on page 14).
4. LEVEL:
This control sets the overall output level of the sub¬
woofer. Adjust it for the best overall blend with your
main speakers, after you have set the other controls.
5. ON /Standby/Limit Indicator:
This indicator glows
red
when the subwoofer is in
Standby. The subwoofer uses very little power in this
mode. It turns on rapidly whenever the main system
is used. This indicator glows
green
while the sub¬
woofer is On and operating.
6. LINE INPUT:
Normally, the Right (R) and Left (L) signal outputs
from a preamp will connect to the to RIGHT IN and
LEFT IN. A mono input, as from a receiver SUB out,
can connect to either input.
7. SPEAKER LEVEL INPUT:
Connect the Right and Left speaker outputs of a
stereo receiver/amplifier
to the plug that inserts here.
8. Option:
The OPTION jack is provided for connection to
future accessories.
