PLACEMENT / POSITIONING OPTIONS
The OMNICAN is the most unique in-ceiling speaker developed to date. Featuring Mirage’s
exclusive OMNIPOLAR technology and other patent pending technological advancements,
the OMNICAN creates an unprecedented spacious soundfield. The OMNICAN distributes
sound evenly into the room, hence allowing for greater coverage and smoother blending
between speakers.
In order to achieve the best results from your new OMNICAN speaker system, it is
important to understand the fundamentals of the technology behind it. Mirage’s
proprietary OMNIGUIDE module is used to reflect sound in a life-like 360 degree
dispersion pattern. It is angled to allow the OMNICAN speakers to create a slightly
forward biased soundfield. This means that a larger proportion of sound is directed
towards a specific area. An arrow on the OMNIGUIDE tweeter reflector indicates this
direction. The OMNIGUIDE module can be rotated up to a maximum of 250 degrees to
simplify the fine-tuning process. The speakers will ship with the OMNIGUIDE module
oriented in the center position allowing a rotation of 125 degrees in either direction. This
center position is marked with a small sticker on the front baffle allowing you to easily
find the center position if the OMNIGUIDE module has shifted during shipping or
installation. For further information please refer to diagram 1.
Depending on whether you are trying to create a diffused or more directional soundfield
there are two general guidelines to follow:
Diffused Soundfield: Mount the OMNICANs with the arrow on the OMNIGUIDE module
pointed towards the side or rear walls, away from the main listening area. This orientation
is particularly suited for surround sound and distributed audio applications.
Directional Soundfield: Mount the OMNICANs with the arrow on the OMNIGUIDE module
pointed towards the main listening area. This orientation is particularly suited for front
speaker applications (left, center, right) or when the OMNICANs are mounted in very large
rooms with the speakers being fairly far apart from one another.
Diagram 2 shows an example of how a 5.1 home theater system could be set-up. The
circles in the diagram illustrate the direction of the sound.
If you are uncertain about the placement of the OMNICANs, you can conduct a very
simple experiment to develop a better understanding of how the speakers may perform in
your room. Place the OMNICANs on the floor with the speaker and OMNIGUIDE module
facing upwards in approximately the same location as they would be when mounted in
the ceiling. Connect the speakers to a receiver (see INSTALLATION INSTRUCTIONS below)
and listen to some familiar music and/or movie tracks. You may want to listen to the
speakers while standing upright in order to increase the distance between your ear level
and the speakers. The idea behind this is to simulate the distance between the ear-level in
your normal seating position and the speakers when mounted to the ceiling. Experiment
with some alternative placements and OMNIGUIDE rotations to get a feel for how the
OMNICANs perform in different positions. Even though this experiment is not 100%
accurate it can offer some valuable insights with regards to how the speakers may
perform in your specific room.
It is important to note that no matter how the OMNICAN is mounted; it will achieve great
performance. The above should be seen as a very general guideline on how to fine-tune
the system, and how to cope with unusually shaped rooms. We highly recommend
experimenting with different angles in order to find the perfect set-up for your room and
to enjoy the tremendous versatility of the OMNICAN series.

INSTALLATION INSTRUCTIONS
NOTE: If you are unable to install the speakers yourself, please contact an
authorized installation contractor, or your authorized Mirage Speaker
Systems retailer. Caution: Turn off all power in your audio/video system
before proceeding with your installation. Not doing so could result in
potential damage to the system.
INSTALLATION - STEP BY STEP
1) Decide on the placement of your speakers. Advanced planning in regards to the placement
of your speakers is critical. In general we recommend leaving approximately 18-24 inches
(45-60cm) of space between the speaker and the walls of the room. Please refer to the
Placement section for further information. The mounting location must be void of wall
studs or bracing. Adequate depth for the speaker to fit flush to the ceiling surface is
important.
2) Once you have determined the speaker’s final mounting position, use the supplied
template and mark the cut-out on the ceiling. To mark the cut-out size, simply trace an
outline of the supplied template. (Diagram 3)
3) Using the appropriate wall-cutting tool, accurately cut the hole into the ceiling.
(Diagram 4)
4) Insert the speaker cable(s) from the receiver or amplifier into the wall or ceiling, and leave
enough slack in the wire so that it can hang out from the hole and allow the OMNICAN to
rotate if necessary (Diagram 5). Using the appropriate wire is essential, as your local
municipality may have certain wiring codes that must be maintained.
5) Connect the speaker wire from the positive (RED +) terminal on the receiver to the
positive (RED+) terminal on the speaker. Connect the negative (BLACK-) terminal on the
receiver to the negative (BLACK-) terminal on the speaker. To connect the wire to the
speaker, completely push the appropriate terminal in, and insert the wire through the hole
that appears on the terminal. Release the terminal and the internal springs will hold the
wire in place. Repeat for the other terminal. NOTE: If you inadvertently reverse one of the
connections (i.e., red to black), you will notice a severe lack of bass from your system. This
is called wiring the system “Out of Phase”. If this occurs, check the wiring and re-connect
as necessary. (Diagram 6)
6) Do not pick the speaker up by the tweeter, as the Pure Titanium Hybrid Tweeter can easily
be damaged if this is done. Instead, use the frame of the speaker to hold it in place.
7) Insert the entire speaker into the hole (Diagram 7). Rotate the OMNICAN into the desired
direction and using a Philips screwdriver, tighten the screws attached to the dog clamps
until firm. DO NOT OVERTIGHTEN (Diagram 8 and 9)
