Definitive Technology CS-8000HD Powering the Active Subwoofer, Troubleshooting, Service, Pre-Out

VERY IMPORTANT:

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

Use the manual speaker setup functions 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. Set center speaker as “Large.”

All Dolby/DTS multi-channel receiver/amplifiers feature a dedicated channel for a center speaker. Consult your receiver's owner's manual for the appropriate connection procedure.

Powering the Active Subwoofer

Your CS Speaker contains a built-in, powered woofer designed to extend the frequency response and dynamic range of the center channel. Do not connect the Low Level input to your receiver’s LFE output. The CS speakers are not designed to be a dedicated subwoofer.

Your CS speaker must be plugged into an electrical socket of the appropriate voltage (as indicated on the back of your unit) using the electrical cord which you have attached to the back of the speaker. When powering up from being unplugged, the LED on the amplifier panel will flash for 30 seconds while the firmware is loading. The CS Speaker has a special circuit which automatically turns the powered woofer section on when a signal is fed to the loudspeaker and does not require an on-off switch. 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 to an hour for the amplifier to actually turn off. In some instances, because of stray radio signals (RF) in your area, the LED may not turn off. However, this is nothing to be concerned about as the amplifier draws little power when at idle.

Setting Your Speakers’ Low-Frequency Level Control

Your CS Speaker has a bass level control which
allows you to tune the output level of the
woofer to match your room and personal
listening preferences. Please note that there
are no controls to vary the crossover points
or phase because these have been
factory-calibrated and set to provide perfect
blending. We suggest beginning with the level
control set at approximately 12 o’clock.	Min	Max

Troubleshooting

If you experience any difficulties with your CS Center Channel loudspeaker, try the suggestions below. If you still have problems, contact your Definitive Technology Authorized Dealer for assistance.

1.Audible distortion when the speaker is playing at loud levels is caused by turning up your receiver or amplifier louder than the receiver or the speaker is 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 speakers in the system 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 main- tain 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.
