The outer connection panel and internal dividing network of the Prelude Forty
loudspeakers are designed so that separate sets of speaker cables can
be attached to the low-frequency transducer and midrange/high-frequency
transducer portions of this dividing network. This is called bi-wiring.
Bi-wiring can provide several sonic advantages and considerably more
flexibility in power amplifier selection.

DJUSTMENTS
Check the speakers for playback, first by setting the system volume control
to a minimum level, and then by turning on the power of your audio system.
Play a favorite music or video segment and increase the system volume
control to a comfortable level.
NOTE:
You should hear balanced audio reproduction across the entire
frequency spectrum. If not, check all wiring connections or consult
the authorized Infinity dealer from whom you purchased the system.
The amount of bass you hear and the stereo-image quality will be affected
by a number of different factors, including the room’s size and shape,
the construction materials used to build the room, the listener’s position
relative to the speakers, and the position of the speakers in the room.
Listen to a variety of music selections and note the bass level. If there is too
much bass, move the speakers away from nearby walls. Conversely, if you
place the speakers closer to the walls, there will be more bass output.
Nearby reflecting surfaces can adversely affect stereo-imaging quality. If this
happens, try angling the speakers slightly inward toward the listening position
until the optimum effect is achieved.

The Infinity Prelude Forty enclosure has a finish that does not require any
routine maintenance. When needed, use a soft cloth to remove any finger-
prints or dust from the enclosure.
NOTE:
Do not use any cleaning products or polishes on the cabinet or grille.
If a problem occurs, make sure that all connections are properly made and
clean. If a problem exists in one loudspeaker, reverse the connection wires
to the left and right system. If the problem remains in the same speaker,
then the fault is with the loudspeaker. If the problem appears in the opposite
speaker, the cause is in another component or cable. In the event that your
subwoofer ever needs service, contact your local Infinity dealer, or go to
www.infinitysystems.com to locate a service center near you.
IMPORTANT:
Please attach your sales receipt to this manual and store it
in a safe place. In the event that your Infinity speaker requires warranty
service, you will need to provide your sales receipt.

* If you are using the dual-amplifier bi-wiring connection, ensure that both amplifiers exhibit the same polarity
output when given the same input signal. Consult your amplifier’s manual or manufacturer if necessary.
