Troubleshooting
If you experience any difficulties with your BP9000 speakers, try the suggestions below. If you still have problems, contact your Definitive
Technology Authorized Dealer for assistance.
1. Audible distortion when the speakers are playing at loud levels is caused by turning up your receiver or amplifier louder than the
receiver or the speakers are capable of playing. Most receivers and amplifiers put out their full-rated power well before the volume
control is turned all the way up, so the position of the volume control is a poor indicator of its power limit. If your speakers distort
when you play them loud, turn the volume down!
2. If you experience a lack of bass, it is likely that one speaker is out of phase (polarity) with the other and needs to be rewired with closer
attention to connecting positive to positive and negative to negative on both channels. Most speaker wire has some indicator (such
as color-coding, ribbing or writing) on one of the two conductors to help you maintain consistency. It is essential to connect both
speakers to the amplifier in the same way (in phase). You may also experience lack of bass if the bass volume knob is turned down or
not on.
3. Make sure all your system interconnects and power cords are solidly in place.
4. Should you hear hum or noise coming from your speakers, try plugging the speakers' power cords into a different AC circuit.
5. The system has sophisticated internal protection circuitry. If for some reason the protection circuitry trips, turn off your system and
wait five minutes before trying the system again. If the speakers' built-in amplifier should overheat, the system will turn off until the
amplifier cools down and resets.
6. Check to be sure that your power cord has not been damaged.
7. Check that no foreign objects or liquid has entered the speaker cabinet.
8. If you cannot get the subwoofer driver to turn on or if no sound comes out and you are sure the system is set up properly, please bring
the loudspeaker to your Definitive Technology Authorized Dealer for assistance; call first
