AIRMOTIV XS SUBWOOFERS
3. Status Indicator
The Status Indicator will be illuminated green when the Airmotiv XS subwoofer is On, and
will be illuminated red when the subwoofer is in Standby Mode.
4. Power Mode Switch
Note: Your Airmotiv XS subwoofer will only operate if the AC POWER Switch is turned ON.
If the AC POWER Switch is OFF, your subwoofer will NOT operate.
When the Power Mode Switch is set to On, the Airmotiv XS will remain On continuously.
When the Power Mode Switch is set to Auto, the subwoofer will turn On automatically when
incoming audio is detected. Once the subwoofer is On, it will remain On for several minutes;
if no audio is detected after several minutes, the subwoofer will return to Standby Mode.
5. Volume Control
This control sets the relative gain of your subwoofer. Use this control to set the overall
amount of bass delivered by your subwoofer to be a good match for the output of your main
speakers.
6. LF Boost Control
The LF Boost control is used to fine tune the response of the Airmotiv XS subwoofer at very
low frequencies to your room and personal preference. The response of your subwoofer
will be flattest with this control set to the vertical (0 dB) position; in the fully counterclockwise
position (left), bass is reduced by approximately -3 dB at 30 Hz; in the fully clockwise
position (right), bass is boosted approximately +9 dB at 30 Hz.
Note: If your system has automatic room correction, you should set this control to its center
(flat) position before running room correction. Then, after running room correction, use the
control to add a little more or less low bass to suit your personal preference.
7. Crossover Control
Airmotiv subwoofers include a built-in 12 dB/octave crossover (low pass filter). This control
allows you to adjust the crossover frequency for the best match with your main speakers. If
you're using your subwoofer with a home theater pre/pro or AVR that has its own
bass management, you should set this control to its highest frequency setting
(fully clockwise - 150 Hz). If not, then the proper setting will depend on your main speakers,
but 80 Hz (about 10 o'clock) is a good starting point - and is often considered to be a
standard setting for home theater equipment.
8. Phase Control
The phase control is used to adjust the phase on your subwoofer to match the phase of
your main speakers. The best setting here will depend on your main speakers and where
your subwoofer is located in relation to them. This control is usually set to the point where
you hear the most bass in the range of frequencies where the subwoofer overlaps with your
main speakers.
