High Level Connection
If the electronics in your system does not have a preamp
level output, the subwoofer can be connected to speaker
outputs using the Speaker Level Inputs. A special plug-in
connector is used to make it easy to use the Speaker
Level Inputs.
To attached the wires to the connector, strip of about
3/8” (8mm) of the insulation. Twist the wire strands into
a bundle. Make sure their are no loose strands. Insert
the wire into the hole in the top of the connector. Turn
the screw in the side of the connector as shown in the
illustration to clamp the wire in place.
NOTE: Be sure to maintain proper polarity — that
is connect + to + (positive to positive) and – to
- (negative to negative). All wire has one conduc
-
tor marked in some way to make it easy to trace
the connections. Typically there is a stripe on the
insulation or a rib molded into it. Or the insulation
will be transparent and the wire strands of one
conductor will be copper colored and the other
will be silver colored.
With a Speaker Level Input connection both the
subwoofer and the main speakers are connected
directly to the amplifier. Consequently the main
speakers will operate full range. Take this into
account when setting the crossover frequency of
the subwoofer. The crossover frequency should be
set at approximately the same frequency where
the bass response of the main speakers starts to
decrease. That will prevent a situation where both
the main speakers and the subwoofer will both be
reproducing a part of the bass range, which would
produce an unnatural sound.
In addition to the connection method shown above you
may also connect the amplifier to the main speakers and
then run extension wires from the main speakers to the
subwoofer. Which one you use will depend largely on
you physical set up of your room.
