2.3 ControL desCriptions (Cont.)
7. pHase: This switch allows you to compensate for having the subwoofer in a different location than the main speakers. This control allows
the signal to be delayed 180 degrees so the output of the subwoofer will blend in with the main speakers. Slide the PHASE switch to “180.”
At the listening position, listen to the mid bass output. If it sounds weak, set PHASE back to “0.”
8. power Led: Power indicator lamp. Glows green in “ON” mode if audio signal is present. Glows red in both “OFF” mode and “ON” mode
if receiving AC power, and if audio signal is not present after approximately 30 minutes.
9. power: Two-position power switch. In the “ON” mode, the subwoofer’s amplifier is automatically activated if an audio signal is present
and will automatically become inactive when there is no audio signal present after approximately 30 minutes. In the “OFF” mode, power is
shut off to the amplifier.
10. VoLtage seLeCtion: XLS products have 120 V and 240 V capabilities and are shipped with voltage specific fuses:

11. power Cord reCeptaCLe: Connect the IEC cord to this receptacle (supplied with the subwoofer). If the IEC cord does not fit in
your AC outlet, please purchase another AC cord from your audio dealer or electrical supply store.
12. repLaCeabLe fuse: Protects system from overload. Refer to qualified service personnel to change the fuse.
2.4 placement
Your XLS Series Powered Subwoofer produces low frequencies which are omnidirectional. As a result, placement requirements for your
subwoofer are flexible and subject to your listening room’s acoustic characteristics. To determine the best position for your subwoofer, start
by positioning it along the same wall, or plane, as your main speakers. Experiment with various locations until you find the location that
sounds best to you.
note: Typically, your powered subwoofer will sound best when placed between the front main satellites.
Caution! Do not place heavy objects of any type, such as televisions on top of any Cerwin-Vega! speaker unless otherwise recommended
by Cerwin-Vega! XLS Series speakers are for residential applications only.
* Refer to the owner’s manual provided by your main speaker manufacturer to determine your main speaker’s low-end frequency response.
