About This Manual

To start enjoying your new Oreus HCS, read and then follow all
instructions listed in this guide, as well as those found in the
owner’s manuals of associated components in your audio system.

Save all instructions for future reference.

TECHNOLOGY

Oreus loudspeakers incorporate several innovative technologies
that, when implemented by our exceptionally talented engineers
after hours upon hours of subjective listening evaluations, result
in a loudspeaker that realistically and accurately reproduces the
signal source with minimal distortion and coloration.

Ceramic Metal Matrix Diaphragms™ (C.M.M.D.)

For decades, loudspeaker engineers have known that the ideal
transducer should be stiff, yet light, and have high internal damping
(damping is a material’s ability to absorb energy).
Infinity’s C.M.M.D. transducer is a significant advance in transducer
technology. Ceramic, a class of material new to loudspeakers,
offers better performance than other materials.
Ceramic is stiffer than metals and lighter than plastics and typical
composite materials; it also offers improved damping.
These ceramic-based transducers take us a giant step closer to the
ever-elusive “ideal transducer.”

In woofer and midrange applications, it offers accurate pistonic
operation over the entire frequency range of the driver, completely
eliminating coloration due to cone breakup and dramatically
reducing distortion. And when ceramic-metal-matrix transducers
are exposed to moisture, sunlight or extreme temperatures, their
performance does not deteriorate.

In addition to ceramic diaphragms, the transducers in Oreus
satellite and center channel speakers incorporate full magnetic
shielding to allow use in close proximity to tv receivers and video
monitors.

PLANNING YOUR SYSTEM

Before deciding where to best place your speakers, survey your
room and study Figure 1.

FIGURE 1– In this overhead view of a typical installation, satellite
speakers are used to reproduce sound for the front and surround
channels. The center channel reproduces sound and dialog.The
powered subwoofer provides extended bass for effects and music.

PLACEMENT

NOTE:

The satellite speakers can be placed directly on a shelf, or mounted
on a wall using the built-in base/bracket.

CAUTION:

The rubber feet can under certain conditions smudge or discolor
light colored and delicate surfaces. Please place a protective mat or
coaster under the rubber feet to prevent marking or discoloration.

For front left and right channels

For front left and right 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.

IF YOU WANT TO STAND YOUR SPEAKER ON TABLE

Feed speaker cable through the foot

1. The foot supplied with your Oreus satellites and center channel
is supplied assembled.

2. Fit the five self-adhesive rubber feet to the foot.

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 Channel

For surround left and right channels, place one speaker on the left
and another on the right, to the sides of or behind the listening area.

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 your Infinity dealer 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.

3. Remove the two fixing screws and lift the pivot cover plate off
the foot. Use the hex key supplied to loosen the screws.

4. Lift out the pivot.

5. Feed the speaker cable through the rear cable-entry hole in the
base and then through the pivot.

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
non-directional, 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.

6. Put the pivot back into place. Re-fit the cover plate and replace
the two fixing screws. Do not fully tighten the screws at this stage
because you will need to rotate the pivot later in the assembly
procedure to angle your speakers correctly.
