Line-level Connection
Figure 1 shows connection to a pre-amplifier's main outputs and returning
them to your amplifier inputs.
When installed in this fashion, your satellite speakers will be crossed over
at 80/100Hz which removes the lower bass from your amplifier and
speakers, enabling them to do a better job reproducing high frequencies.
By utilizing this method, you will have a bi-amplified system, gaining
improved power and headroom for your system.
Subwoofer outputs
Your DLS subwoofer is designed to operate using the full range audio
signal for input when using the built-in crossover. Many home theater
processors/receivers (Dolby Digital, DTS, THX) have a "subwoofer out"
jack that is internally filtered and designed to be used with a powered
subwoofer.

In these installations,  you may bypass the internal crossover in either the
processor or your DLS subwoofer. In some installations, it may be
beneficial to have a steeper ultimate crossover slope.  To do this you can
use both your processor's crossover and the one internal to the DLS
subwoofer.  You should stagger the frequencies (i.e., 120Hz sub, 80Hz
processor) for best results.
To bypass the subwoofer's internal crossover when the unit is being fed
a low pass signal from another crossover, simply locate the switch marked
"SUBWOOFER DIRECT/INTERNAL X-OVER" on the rear panel of the
subwoofer and set to the "SUBWOOFER DIRECT" position.  This will
eliminate the internal crossover from the signal path.
Note. . .
If not using an external crossover, you should use the built-in crossover
for optimal performance.  When using a single channel input signal
(such as a surround sound processor's subwoofer out, or LFE), the auto
on/off circuit sensitivity will be affected.  When one input channel is
used instead of two, the unit will see lower signal levels present at the
inputs.  This may cause the unit to turn off when listening at low volume
levels.  If this occurs, simply use a "Y" adapter (available from most
dealers) to allow your processor's single sub line to be fed into both L&R
inputs.  This will make the unit turn on at lower signal levels.
Speaker-level Connection
Figure 2 shows an easy way to connect your DLS subwoofer directly to
your receiver or integrated amplifier.
When connected in this fashion, your satellite speakers will be crossed
over at 80/100Hz which removes the lower bass from your speakers,
enabling them to do a better job reproducing high frequencies.
You may also connect your satellites directly to your receiver or amplifier
along with the subwoofer if you wish to bypass the internal high-pass
crossover.
