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
dowQ.
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 LFE (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 ampli-
fier 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 experience
any level
of
ground hum or noise, try plugging the subwoofer into the
same circuit
as
your amplifier. Also, consult the "Troubleshooting" sec-
tion
of
this manual.
To
prevent accidental damage to your subwoofer
from overdriving the system, the subwoofer features an internal overload
protection circuit.
