WIRING THE SYSTEM
FINAL ADJUSTMENTS
IMPORTANT: Make sure all equipment is turned off before making any
connections.
Check the speakers for playback, first by setting the system volume con-
trol to a minimum level, and then by applying power to your audio system.
Play a favorite music or video segment and increase the system volume
control to a comfortable level.
For speaker connections, use a minimum # 16-gauge speaker wire with
polarity coding.The side of the wire with a ridge or other coding is
usually considered positive polarity (i.e., +).
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
for more help.
NOTE: If desired, consult your local Infinity dealer about speaker wire and
connection options.
The speakers have coded terminals that accept a variety of wire connec-
tors.The most common connection is shown in Figure 4.
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.
To ensure proper polarity, connect each + terminal on the back of the
amplifier or receiver to the respective + (red) terminal on each speaker,
–
as shown in Figure 5. Connect the (black) terminals in a similar way.
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.
See the owner’s guides that were included with your amplifier, receiver
and television to confirm connection procedures.

IMPORTANT: Do not reverse polarities (i.e., + to or to +) when
making connections. Doing so will cause poor imaging and diminished
bass response.
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.
CARE OF YOUR SPEAKER SYSTEM
Each Primus series cabinet has a wood-grain-vinyl finish that does not
require any routine maintenance.When needed, use a soft cloth to remove
any fingerprints or dust.
Clean the grille by gentle vacuuming.
NOTE: Do not use any cleaning products or polishes on the cabinet
or grille.
