Troubleshooting
If you experience any difficulties with your BP9000 center channel 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 than your amplifier.
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.
