REAR PANEL CONNECTIONS
Your new subwoofer is equipped with both speaker-level and line-level inputs. Use the RCA/Phono type “INPUT”
jacks when connecting your subwoofer to a pre-amp, signal processor, or line-level crossover. The “SPEAKER
LEVEL INPUT” jacks connect directly to the speaker outputs of an integrated amplier or receiver. Your amplier
section will notice no additional loading eects when you use these inputs because of their high impedance.
Note: Do not use both the RCA/Phono “INPUT” connections and “SPEAKER LEVEL INPUT” connections
simultaneously.
Low-Pass Crossover
Both sets of inputs sum the left and right channels together and the resulting signal is passed through an
adjustable low-pass crossover before being amplied. The crossover control allows you to adjust the upper
limit of the subwoofer’s frequency response from 40 to 120 Hz. The subwoofer’s response will begin rolling o
above the frequency you set this control to.
You should set the crossover frequency to obtain a smooth and seamless transition from the subwoofer to the
main speakers in your system. If your main speakers are smaller units with limited low frequency output, you
may wish to choose a higher frequency (such as 100 -120 Hz) 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 80 Hz.
Subwoofer Direct
Subwoofer Direct is a setting on the low-pass crossover knob and will allow frequencies up to 200 Hz into the
subwoofer. See below for a more detailed explanation of this feature.
Speaker Level Output/Line Level Output
When connected in this fashion, your satellite speakers will be crossed over at 80 Hz. This removes the lower
bass from your satellites, enabling them to do a better job reproducing high frequencies and giving your
receiver’s amp more headroom (up to 50% more power). You may also connect your satellites directly to your
receiver or amplier along with the subwoofer if you wish to bypass this crossover.
Caution!!!
To avoid damage to your main amplier, be sure to maintain correct polarity when making all connections.
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.
Power Switch
The master power switch is located on the lower right half of the unit. This rocker style switch is the main on/o
for the unit. This switch should be set to position 1 for on (up), 0 for o (down).
