Crossover (Hz): Adjusts the frequency of the lowpass filter for the subwoofer.

Power off/on: Switches the amplifier on and off. Once switched to the “on” position, the XB2’s auto-on circuitry

turns the subwoofer on when a signal is presented, and turns it off after no signal is detected for several minutes.

Polarity (0° or 180°): Selects regular (0°) or inverted (180°) polarity for the subwoofer. Set this switch to provide

the fullest, most dynamic bass. The effect of phase will be most audible on low-frequency percussion instruments

or music with a continuously repeating bass line.

Volume: Adjusts the sound level of the subwoofer. A typical setting is around 11 o’clock.

Placement

Place the subwoofer next to a wall or in a corner near your front/main speakers. Typically, the sound is best when the

subwoofer is within 15 feet (5m) of the front/main speakers. However,the sharp 24dB/octave crossover roll-off per-

mits placement farther from the front/main speakers if necessary. Since the ear is unable to localize the low

frequencies of the subwoofer, the bass still appears to come from the front/main speakers. In most cases, the

subwoofer may be placed anywhere in the listening room.

The level of bass output from the subwoofer will vary at different positions in a room. When placed near walls, its loud-

ness is emphasized. Corner placement provides the most bass output, while placement near only one wall will provide

somewhat less bass. Placement completely away from walls may produce too little bass. Regardless of how you place

the subwoofer, you can adjust the subwoofer’s level with its rear panel level controls. If you move the

subwoofer,recheck the setting of the polarity switch. Use the setting that yields the louder and moredynamic sound.
