Connections
NOTE: Power is always supplied to the subwoofer electronics unless it is unplugged from the power outlet.
The auto-on circuitry only activates or deactivates the power amplifier. Make sure your subwoofer and receiver are
unplugged when making the connection.
Line level: Use one of the “line level in” jacks with most systems. These inputs accept the line level signal from
your receiver’s subwoofer output. When using the “
use crossover control” input, the subwoofer’s circuitry filters
out the high frequencies and sends the remaining low frequencies to the subwoofer power amplifier.
Speaker level: Use these high-level terminals with receivers that do not have a subwoofer output. The speaker
inputs accept both left and right channel speaker signals from your receiver.
How to Connect Using the Speaker Terminals
We recommend 18-gauge wire or thicker for runs up to 15 feet (4.5m), and 16-gauge wire or thicker for longer runs.
Separate the first few inches of the wire conductors. Strip off
1
⁄
2
-inch (13mm) of insulation from the ends of each
speaker wire to expose the two conductors and tightly twist the wire strands.
WARNING: To prevent electrical shock hazard, always switch off the amplifier or receiver when making connections
to the speaker.
When making all connections, be sure to connect the + (red) on the speaker to the + (red) on the amplifier, and
the – (black) on the speaker to the – (black) on the amplifier.
IMPOR
TANT:
T
ypically, one side of the wire is smooth.
Connect this side to the – (black) connection. The
other side has a rib or stripe. Connect this to the +
(r
ed) connection.
Using the spring ter
minal posts:
The spring
terminal posts permit easy connection to
banana plugs, spade lugs, and bare wire.
Push the the top of the terminal down by
approximately
1
⁄
4
-inch (6mm), exposing the
hole. Insert the wire in the hole and release the
ter
minal.
