RUNNING WIRES IN WALLS OR CEILINGS
When running wire inside walls or ceilings, use special jacketed cable (CL-2 or CL-3) to protect
the wire and to meet local electrical and fire codes. In some areas, conduit is also required. For a
trouble-free installation, low-voltage wire such as loudspeaker wire must be run in accordance with
the National Electrical Code and any applicable provisions of the local building code. If you are unsure
of the correct installation techniques, wire jacket, or type of conduit to use, consult a professional
audio/video installer, building contractor, or the local building and inspection department.
CONTROLS AND CONNECTORS
The SWA-500M’s easy operation controls are located on the unit’s front panel, as shown in
Figure 6. The controls function as follows:
1. (Master) POWER Switch: Use this control to power the SWA-500M On or Off.
2. MUSIC/MOVIE LEVEL and SETUP Controls: Because bass levels will differ depending
on whether you are watching a movie or listening to music, the SWA-500M includes
MUSIC/MOVIE LEVEL and SETUP Controls. While listening to music, push the SETUP
switch to MUSIC and adjust the MUSIC LEVEL control to set your desired bass level.
Similarly, while listening to a movie, push the SETUP switch to MOVIE and adjust the
MOVIE LEVEL control to set the desired bass level. Each level control includes an LED
indicator to identify which one is currently active as triggered by your home theater
sound processor or receiver. Also see CALIBRATING THE SWA-500M on page 15.
3. LOW PASS Frequency Control: Use this control to set the subwoofer’s low-pass
crossover frequency from 40 to 120 Hz. For more details, see CALIBRATING THE
SWA-500M on page 15.
4. PHASE Control: Use this control to set the subwoofer’s phase response from 0 to 180°.
