Figure 12. Subwoofer Wiring Methods
ATTENTION:
• Do not tin the wire leads before installing into the connector. Tinned wires are
not as secure in the connector and could be pulled out.
•
Ne pas étamer les conducteurs avant de les insérer dans le connecteur. Les
câbles étamés ne sont pas aussi bien fixés dans le connecteur et pourraient
être retirés.
5. Insert the captive screw plug into the four-pole receptacle of the subwoofer (see
figure 11 ,
3
, on the previous page) and screw it into place.
6. Replace the access plate and tighten the retaining screw.
7. Tighten the cable clamp if it was used.
Operational Considerations
Play content that you are familiar with through the system and verify that it sounds as
expected.
• Set the gain structure through the audio system appropriately.
• Set the gain on the subwoofer and speakers such that they are at the same sound
pressure level.
• If any distortion is heard, you may be driving the subwoofer too hard and may need to
add additional subwoofers to the system to get the desired sound pressure level.
