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. Please take care to perform all wiring procedures with your system

completely powered down.

Unpacking

Each loudspeaker leaves our plant in perfect condition. Any visible or concealed damage most likely occurred in handling after it left our plant, and should be reported at once to your Deﬁnitive dealer or the delivery company that delivered your loudspeaker. Please unpack your system carefully. Save all cartons and packing material in case you move or need to ship your system. Record the serial number found on the back of the subwoofer in the appropriate place on your warranty card.

Inputs/Outputs

Your Deﬁnitive Technology ProSub subwoofer operates from either high level (speaker-type) or low level (RCA-type) outputs on your electronics. Use the low level jack when connecting the subwoofer to the LFE output jacks of a receiver, a preamp or a signal processor. Use the high level speaker terminal inputs to connect the subwoofer to the ampliﬁer output (speaker) jacks of your receiver or ampliﬁer. Use the high level output jacks to connect the subwoofer to a pair of left and right main speakers. (See wiring diagrams.)

When connecting the subwoofer to your system, it is recommended that you use high quality speaker cable and try to maintain cable runs of the same length for the left and right channels. Should you perchance experience any level of ground hum or noise, try plugging the subwoofer into the same circuit as your ampliﬁer. Also, consult the “Troubleshooting” section of this manual. To prevent accidental damage to your subwoofer from overdriving the system, the subwoofer features an internal overload protection circuit.
