Subwoofer Installation Your new ProSub Subwoofer contains a built-in amplifier and sophisticated electronic crossover. There are several ways to install your subwoofer. One setup is not considered "better" than another; rather, each is a function of what type of entertainment system you own and how you plan to integrate your components. Read the installation suggestions below to determine which options best suit your needs.
Subwoofer Placement Your Definitive Technology subwoofer has been designed to operate at frequencies generally below 150 Hz. Because low-frequency information in this range essentially is non-directional, your subwoofer can be located anywhere in your listening room that is most convenient. Also, the continuously variable low pass filter operates at a very fast roll-off, ensuring great performance wherever you place your subwoofer.
High Level Speaker Wire Connections Your Definitive Technology ProSub subwoofer can also be hooked up via high level connections. In this situation, you have the option of running your main speakers "full range" or rolling off the low end by using the high pass filter built into the subwoofer. For high level wiring, your interconnects are simply equal distance lengths of high quality speaker cable.
bass output when using full range main speakers, run the main speakers full range by hooking them up directly to the amp. In many systems, if your speakers are true full range systems, you may find that you get a more satisfying sound by running the speakers full-range and crossing your subwoofer in fairly low setting (40-70 Hz).
smoothes out the peaks and dips which result from the eigenmodes in your room. Two subwoofers couple much better to the air in your room (four times better) and of course offer double the power. In addition, some state-of-the-art home theater installations have begun to use a separate subwoofer hooked up to the rear (surround) channels and we recommend this for the absolute ultimate in performance.
Operating Controls Your Definitive Technology ProSub subwoofer is equipped with a full complement of operating controls to ensure complete flexibility and maximum performance in any installation. Most of them basically are the "set and forget" type, although occasionally certain controls will require minor adjustments. Gain Control On the side of your subwoofer is a gain (volume) control.
current going to it, it will reactivate itself with a pop when AC current is restored, which is normal. Please note that after the cessation of a signal, it may take up to an hour for the amplifier to actually tum off from active to staildby mode. In some instances, because of RF presence in your area, the red LEDs may not tum off. However, this is nothing to be concerned about as the amplifiers draw almost no power when they are idling.
Troubleshooting If you experience any difficulties with your subwoofer, try the suggestions described below. If you are still having problems, please consult your Definitive Technology Authorized Dealer for assistance. 1. Make sure all your system interconnects and power cords are solidly in their place. 2. Should you experience any level of ground hum or noise, try plugging the subwoofer into the same circuit as your amplifier.
