PLACEMENT  
Subwoofers offer the greatest variety of placement options since very low frequencies are essentially non-directional.  
That is, the human ear cannot determine where low frequencies originate and, thus, speaker placement is open to a  
wide variety of choices. It is recommended that you place the subwoofer along the same wall as your front speakers.  
If using one subwoofer, corner placement will give you the most low frequency output. If using two subwoofers, they  
should be placed either next to the front left and right speakers, both front corners, or one in the corner and one 1/3  
of the way along the front wall from the corner. Each room is different. Experiment with these options until you get  
the best results.  
HOOKING UP YOUR POWER FL SUBWOOFER  
Option 1: Low Level Setup  
This is the recommended method for those ampliers and receivers that are equipped with a “Subwoofer Out” or  
“Pre-Amp Out” connection. Virtually all audio/video receivers have this connection clearly marked on the rear panel.  
Run a dedicated interconnect cable from the subwoofer output jack to the LFE input on the subwoofer. In this setup,  
you will be using the internal crossover on your processor.  
You may also connect a single output amplier/receiver to both low level inputs by using an RCA-Type “Y” connector  
at the back of the amplier and running two cables to the subwoofer inputs.  
Note: Many more home theater receivers have a built-in processor to control how much bass is sent to the speakers.  
Please read the instruction manual for your own electronics and adjust these settings prior to playing your new  
subwoofer.  
Option 2: High Level Input Setup  
If your amplier or receiver does not have a dedicated subwoofer output, it will be necessary to connect your new  
subwoofer directly to the speaker output terminals on the back of the unit. In this scenario, you will be running  
high quality speaker wires from the left and right front outputs of your amplier/receiver too the high level inputs  
on the subwoofer. You will then need a second set of wires to carry the signal from the subwoofer back to the main  
speakers.  
Note: Many home theater receivers/ampliers have a “Bass Management” feature that controls how the bass is  
processed/delivered to the subwoofers. Look carefully if your amplier or receiver’s instruction manual for details on  
how to adjust this feature for your system. Then adjust the subwoofer controls for best sound.  
POWER FL SERIES AMPLIFIER PANEL  
(See Power FL Amplier Panel Image on Next Page)  
1. Power/Auto ON/OFF: This switch, when left “ON,” automatically activates the subwoofer when an audio signal is  
detected and shuts the subwoofer off after approximately ten (10) minutes of silence.  
2. Level/Volume Control: Adjusts the volume of bass energy allowing you to customize overall tonal balance to your  
individual room acoustics and personal taste.  
3. Crossover Control: This adjustment varies the point at which the subwoofer takes over the task of creating low  
bass frequencies from the rest of the audio signal permitting additional ne tuning of the total system. A little  
experimentation with this control will allow you to match the performance of the subwoofer to the rest of your  
speakers resulting in extraordinary, accurate, deep bass response. This control is bypassed when the LFE input is  
used.  
 
4. Servo Control: This features automatically protects the  
subwoofer against damage which can be caused by excessive  
amplier power and/or distortion. Phase Tech’s servo control  
system constantly monitors the incoming signal. This active  
protection circuitry provides listeners with the full dynamic  
range of sound while protecting the subwoofer from potential  
damage.

5. Phase Control: This adjustment matches the phase - the in  
and out movement of speaker cones - to that of your main  
speakers. Adjusting this control provides the best possible  
bass frequency response and provides a method by which to  
match the performance of all speakers in the system.

6. LFE Input: The Low Frequency Effect (LFE) input or switch built  
into Phase Technology’s subwoofers bypasses the built-in  
crossover network, allowing accurate control of the subwoofer  
by A/V receivers equipped with their own “Subwoofer Out”  
connection. Depending on the model of your subwoofer, there  
will be an FLE input or an FFE switch. To use the LFE switch,  
connect your “Subwoofer Out” from the receiver to the “Low  
Level Input” on the subwoofer and turn the LFE switch on.
