There are two reasons to use this connection option. The first is if your receiver has no RCA
subwoofer output jack! The second is if your system would benefit from having the bass filtered out of the
main speakers. (If you have a Dolby Digital or DTS receiver you can achieve the same results electronically
simply by configuring your main speakers as SMALL and connecting your sub via a Phono cable - See Option
#1). If you have large main speakers that are capable of reproducing a great deal of bass on their own then
this connection option may not be advantageous to you. If however you have small main speakers then this
method deserves consideration. Since this connection method filters out the low bass from the main
speakers it provides the beneficial effects of increasing their power handling and improving their clarity.
If you choose to use this connection option, simply run speaker wire from your receiver’s speaker
outputs to the subwoofer inputs marked Input from Receiver / Amp. Then, wire your left and right front
speakers to the subwoofer outputs marked Output to Speakers. Please refer to the Option #2 wiring diagram
for further clarification. Place the Crossover Bypass Switch on the subwoofer in the OFF position (this
activates the Low Pass Filter).
POWER-UP AND TONE CONTROL ADJUSTMENTS:
•
Plug your subwoofer into any ordinary wall outlet. Since your subwoofer can require up to 800 Watts of
power, do not plug the subwoofer into any outlet that cannot deliver 800 Watts (like those on the back of
other electronic equipment such as your receiver).
•
With the VOLUME control at minimum (maximum counter-clockwise position), plug in the subwoofer’s
power cord and turn the power switch on the subwoofer’s control panel to the ON position. The Auto-on
circuitry will automatically turn the unit on (LED turns green) when it receives an audio signal. It will also
automatically turn the unit off (LED turns red) after a few moments without any audio signals. If for any
reason you do not want your subwoofer on, simply turn the power switch to the off position.
•
Please ensure that your receiver’s loudness control is off and that the bass tone control is in its middle (no
boost) position. Now play some music with ample bass content. (The following setup routine is best
accomplished with one person seated in a normal listening position directing another to adjust the controls
for the best sound.)
•
Adjust the VOLUME level on the subwoofer’s control panel so that the output level of the subwoofer is
satisfactory (relative to your front speakers). If either of your front speakers or subwoofer are not
functioning properly, please refer to the Troubleshooting section toward the end of this manual.
