Setting Your Speakers’ Low-Frequency Level Control

Your Bipolar STs have bass level controls which allow you to adjust the output
level of the powered subwoofers to match your room and personal listening
preferences. Please note that there are no controls to
vary the crossover points or phase. The crossover
points and phase have been factory-calibrated to
provide perfect blending. We suggest beginning with
the level control set at approximately 12 o’clock.
Each speaker’s bass controls can also be set differently
in order to allow you to compensate for asymmetrical
positioning of the speakers in your room (i.e., when
one is closer to a side wall or corner, etc.).	Min	Max

Wiring Options: High Level, High Level and LFE w/ “Y” Connector

VERY IMPORTANT:

Do not use your receiver’s auto setup functions as they are often ineffective in setting up and adjusting speakers with built-in powered subwoofers!

Complete Home Theater System

We strongly suggest that you use matching Definitive center channel and rear/surround speakers to complete your Definitive home theater system. Please note that you can use Definitive Bipolar SuperTowers as rear or side surround speakers with excellent results for both music and movies.

Troubleshooting

Use the manual speaker setup func- tions in your receiver to set speaker configuration, speaker distance and channel balance. Consult your receiver’s or processor’s manual to learn how to access and use the setup menus. Use the settings called for in

If you experience any difficulties with your Bipolar ST loudspeakers, 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

Powering the Active Subwoofer

Your Bipolar STs contain a built-in subwoofer amplifier that must be plugged into an electrical socket. When powering up from being unplugged, the LED on the amplifier panel will flash for 30 seconds while the firmware is loading. The Bipolar ST has a special circuit which automatically turns on when a signal is fed to the loudspeaker. The LED on the back panel will light up when a signal is sensed and the amplifier turns on. After the cessation of a signal, it may take up

	(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).
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 over-heat, 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.
