NOTE: The satellite speakers can be placed on a shelf, or mounted on a
wall using the supplied wall brackets. Alternatively, the floor stands permit
free positioning around the room.
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 Figure 1. Since the speakers are
magnetically shielded, you can place them very close to the TV without
worrying about the magnetic field distorting the picture. The friction
stands let you tilt the speakers towards you if they are higher or lower
than your ears.
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.
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 1.2 and
2 meters.
Subwoofer
Since the installation of a subwoofer can be somewhat more complicated
than installing full-range speakers, it is essential that you read this
section very carefully prior to connecting the subwoofer to your system.
Should you have questions relating to installation, it is advisable to call
either your dealer or Infinity’s Customer Service Department for advice.
The performance of the subwoofer is directly related to its placement
in the listening room and how you align the subwoofer with the satellite
speakers. Setting the volume of the subwoofer in relation to the left and
right speakers is also of critical importance because it is essential that
the subwoofer integrate smoothly with the entire system. Setting the
subwoofer’s volume level too high will result in an overpowering,
boomy bass. Setting the volume level too low will negate the benefits
of the subwoofer.
Here are several additional facts on installation that may prove useful.
It is generally believed that low frequencies (below 125Hz) are
nondirectional and, therefore, placement of a subwoofer within any
listening room is not critical.While in theory it is true that the larger
wavelengths of extremely low frequencies are basically nondirectional,
the fact is that, when installing a subwoofer within the limited confines
of a room, reflections, standing waves and absorptions generated within
the room will strongly influence the performance of any subwoofer system.
As a result, specific location of the subwoofer becomes important, and we
strongly recommend that you experiment with placement before choosing a
final location. Placement will depend upon your room (for example, whether
or not your room permits placement of the subwoofer near either satellite)
and the amount and quality of bass required.

The PHI satellites are equipped with their desk stands right out of the box.
This means that you can simply place them on any shelf or table just as
they are. Only if you wish to mount them on a wall or put them on floor
stands, is it necessary to detach the desk stands.
1: Remove the trim cover hiding the cable terminals.
2: Remove the central screw at the bottom of the desk stand.
You are now ready to either wall mount your satellites or to attach them to
floor stands.

The PHI satellites are designed to be mounted on the wall. There is a wall
bracket for each satellite speaker.
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.
Step 1.
Mark the positions on the wall where you would like to place the mounting
screws.
Step 2.
Place bracket against wall and fasten two appropriate screws through the
bracket’s screw holes into the wall. The wall brackets have a hole in the
back for cables that are installed into the wall. Make sure that enough
cable is free to reach the plus and minus terminals on the back of the
speaker and then dress it through the hole in the bracket before securing
the bracket onto the wall. Refer to the Center and Satellite Speaker
Connections.
After having secured the bracket on the wall with the wire hanging through
the hole, attach the two leads to the terminal screws on the speaker, and
secure the speaker to the wall bracket with the single central screw.
If you do not run wires inside the walls, you may dress the wires to run out
of the bottom of the wall bracket. There is a break-out section in the plastic
of the wall bracket made for this purpose. Simply break this section away to
open access. You may dress the cable inside a cable tray to make a nice,
clean-looking installation.
