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.
Subwoofer Installation
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.
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
. Please note that
some cable TV hookups induce hum into the whole system and
require a special isolation device. Please consult your dealer.
3. The system is provided with sophisticated internal protection
circuitry
. If for some reason the protection circuitry is tripped, please
turn down your system’s volume and wait five minutes before trying
the system again. If the amplifier should overheat, the system will
turn itself off until the amplifier cools and resets.
4. Check to be sure that your power cord has not been damaged.
5. Check that no foreign objects or liquid has entered the cabinet.
6. If you cannot get your subwoofer to turn on or if no sound comes out
and you’re sure the system is set up properly, please bring the sub-
woofer to your Definitive T
echnology Authorized Dealer for assistance.
