main speakers are smaller units with limited low frequency output, you may
wish to choose a higher frequency (such as 100-120Hz) than you would with
larger speakers which have greater low frequency output. With larger
speakers, you might start with this control set lower, such as 80Hz.
Subwoofer Direct
A bypass switch is also provided if you wish to use an external crossover.
If you are not using an external crossover, we recommend that you use the
one provided within the unit for optimum performance.
Phase adjustment- 0°/180°
This control allows you the "reverse" the phase of the subwoofer's output
signal 180° to correct for any possible mismatch and resulting cancellation
between the subwoofer and your main speakers/amplifier. To adjust,
simply listen to the system with music playing. Then move the switch
from one position to the other and listen for a change in low frequency
output. The correct position will have a greater amount of apparent low
frequency output.
Auto turn on function
With this function in the "auto" position, your subwoofer can be safely left
with the main power switch on continuously. The subwoofer will turn itself
on automatically when an audio signal is present. If no signal is present
for approximately 10 minutes, the unit will switch to standby mode. While
in standby mode, your subwoofer will draw very minimal power. Leaving
the switch in the "on" position can disable this function.
High pass crossover switch
This switch selects the frequency for the high pass crossover. This
crossover is functional on both line and speaker-level outputs. Smaller
speakers with limited low frequency output may prefer the higher 100Hz
setting which will reduce the low frequencies sent to them. Larger
speakers with greater low frequency output may be able to handle the 80Hz
setting without strain.
Power switch
The master power switch is located on the right half of the unit. This rocker
style switch is the main on/off for the unit. This switch should be set to
position 1 for on (up), 0 for off (down).

Interconnect Cables
When installing your new DLS subwoofer using the line-level connections,
you should always use shielded phono cables. There are many decent
cables available today, most any of which will work perfectly well. We do
recommend that you keep the length of cable as short as possible to avoid
any potential noise problems.
When using speaker level connections, use a decent quality speaker cable
that mates well with the connectors. Be very careful to avoid any loose
strands or frayed wires which may result in a short, which may damage
your equipment. Cables of extremely large size are typically not required.
Extremely large gauge wire may not properly fit in the binding posts,
resulting in a poor connection and possible short circuits.

Caution!!!
To avoid damage to your main amplifier, be sure to maintain correct
polarity when making all connections. The correct method is to connect
red (positive) to red and black (negative) to black. Be sure that all
connections are tight, and that there are no loose strands or frayed wires.
