Infinity Primus Series  
The Primus Series of loudspeakers continues Infinity’s  
longstanding commitment to accurate sound reproduction. Our  
proprietary Metal Matrix Diaphragm(MMD®) drivers, precision  
dividing networks and rigid, well-braced enclosures combine to  
deliver uncompromised performance in any stereo or multichannel  
home theater system. In addition, Primus Series speakers are  
magnetically shielded for safe placement adjacent to a television.

WALL-MOUNTING THE SATELLITES AND  
CENTER CHANNEL  
The Primus Theater Pack II satellites and center channel are  
designed to mount directly to a wall. Each satellite speaker has two  
keyholes on the back. Each speaker will require two (2) 1-1/2"  
#10 wood screws fastened to a wall stud. If a wall stud is  
unavailable, install anchors appropriate for 1-1/2"#10 screws.  
PLACEMENT  
NOTE: The satellite speakers can be placed directly on a shelf, or  
mounted on a wall using the built-in keyhole mount or optional  
wall brackets.  
Left and Right Front Channels  
For left and right front channels, place one satellite to the left  
and another to the right of the television, as shown in Figures 1  
and 2. Since the speakers are magnetically shielded, you can  
place them very close to the TV without worrying about the  
magnetic field distorting the picture.  
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.  
Center Channel  
For the center channel, place the speaker directly on top of,  
or below, your television. Use a shelf if the television does not  
provide a stable platform.  
Step 1.  
Mark the position on the wall where you would like to place the  
mounting screws.  
Figure 3.  
Surround Channels  
For left and right surround channels, place one speaker on the  
left and another on the right, to the side of or slightly behind the  
listening area.The surround speakers should be mounted at a  
height of between 4 feet and 7 feet.

Optional Subwoofer  
Adding an Infinity powered subwoofer to the Primus Theater  
Pack II will add the low-frequency information found in many  
recordings. Infinity manufactures several powered subwoofers  
that will deliver the impact and realism of today’s music and  
movie soundtracks. Consult your Infinity dealer for help in  
determining which subwoofer is best for you. If you already  
own a subwoofer, consult the subwoofer’s manual for proper  
installation and connection instructions.

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 appropriate anchors.  
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 then  
become secure.  
Each satellite also allows for 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 brackets.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.

CENTER AND SATELLITE SPEAKER CONNECTIONS  
Turn Off All Power  
After placing the speakers, you are ready to connect your  
system. First, turn off all audio-system power. Use high-quality  
speaker wire to make your connections. Use at least #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., +). Also, consult the owner’s manuals that were included  
with your amplifier or receiver to confirm connection  
procedures.  
Center Channel  
Observe polarities when making speaker connections, as shown  
in Figure 5. Connect each + terminal on the back of the  
amplifier or receiver to the respective + (red) terminal on the  
speaker. Connect the – (black) terminals in the same way.  
Important!  
Do not reverse polarities (i.e., + to – or – to +) when making  
connections. Be certain that positive and negative wire strands  
are completely isolated to avoid short circuits that may damage  
your equipment.  
Satellites  
Observe polarities when making speaker connections, as shown  
in Figure 4. Connect each + terminal on the back of the  
amplifier or receiver to the respective + (red) terminal on each  
speaker. Connect the – (black) terminals in the same way.  
Important!  
+
Do not reverse polarities (i.e., + to – or – to +) when making  
connections. Doing so will cause poor imaging and diminished  
bass response. Be certain that positive and negative wire  
strands are completely isolated to avoid short circuits that may  
damage your equipment.  
Figure 5.The satellites and center channel speaker feature  
terminals that can be connected in several different ways:  
e.g., banana plugs, spade terminals and direct wiring  
(as shown here).

OPERATION  
MAINTENANCE AND SERVICE  
The satellite and subwoofer enclosures may be cleaned using a  
soft cloth to remove fingerprints or to wipe off dust.  
Surround Modes  
When using the system in a Dolby® Digital or DTS® home theater  
system, make sure all speakers are set toSmall.  
The grilles may be gently vacuumed. Stains may be removed with  
an aerosol cleaner, following its instructions. Do not use any  
solvents on the grille.  
Some Dolby Digital-equipped receivers/processors offer different  
setup options for each source or surround mode; e.g., CD-stereo,  
videotape, Dolby Pro Logic.® In each case, follow your equip-  
ment’s instructions to ensure that the subwoofer output is turned  
on (if you are using a subwoofer) and that the speakers are set  
toSmallin each mode.  
All wiring connections should be inspected and cleaned or  
remade periodically.The frequency of maintenance depends on  
the metals involved in the connections, atmospheric conditions,  
and other factors, but once per year is the minimum.  
When using the Primus Theater Pack in a Dolby Pro Logic home  
theater system, make sure the receiver’s center channel mode is  
set toNormal.”  
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 loud-  
speaker. 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  
center near you.
