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.


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.


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.



Feed speaker cable through the foot

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


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


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.

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.

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

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

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.


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.

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, specif ic 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.

4. Lift out the pivot.

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

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.
