CHANGING THE P252 AND P362 FEET
WALL-MOUNTING THE P142, P152 AND
The P252 and P362 feature attractive outboard feet, installed at the
factory. However, if you would like to replace them with the less visible
inboard feet (included), follow the instructions below.
PC250
The P142, P152 and PC250 are designed to mount directly to a wall.
Each speaker has two keyholes on the back, and will require (2) 1-1/2,"
#10 wood screws fastened to a wall stud. If a wall stud is unavailable,
install an anchor appropriate for a 1-1/2,"#10 screw.
1. Remove the four feet on the bottom of the speaker by loosening the
screw in each foot. Keep the screws for later use.
NOTE: The customer is responsible for the correct selection and use of
mounting hardware (available through hardware stores) that will ensure
the proper and safe wall-mounting of the speakers.

2. Remove the rubber plug from each inner hole (and save for possible
future use).

3. Attach the black inboard feet to the inner holes from which you just
removed the rubber plugs, using the same screws you just removed.
4. Hand-tighten securely, using a handheld Phillips (+ tip) screwdriver.
Do not use a powered screwdriver of any type.
Step 1.
Mark the positions on the wall where you would like to place the mounting
screws.
Step 2.
Fasten two 1-1/2,"#10 wood screws to the wall using the markings
placed in Step 1 as your guide. Leave an 11/16" space between the wall
and screwhead. If a wall stud is not available, use an appropriate anchor.
Step 3.
Place the speaker on the wall by aligning the keyholes on the back of the
speaker to the screwheads on the wall. Once positioned properly, the
speaker should slide down slightly and become secure.
The P142 also allows the use of third-party wall brackets using the
1/4"-20 threaded insert located beneath the keyhole mount. Consult the
wall-bracket manufacturer for selection of proper bracket.ker on the wall
by aligning the keyhole on the back of the speaker to the screwhead on
the wall. Once positioned properly, the speaker should slide down slightly
and become secure.
CAUTION: Floorstanding (tower) loudspeakers have a high center of
gravity and may become unstable and tip over during earthquakes, or
if rocked, tipped or improperly positioned. If this is a concern, these
speakers should be anchored to the wall behind them, using the same
procedures and hardware customary for anchoring bookcases and wall
units.The customer is responsible for proper installation and proper
selection of hardware.

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 control
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 5.
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 6. 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.
In the event that your Infinity speaker needs service, contact your Infinity
the nearest service center.
