NOTE: When mounting the speakers at a height of under six feet, orient the
OMD-5 speakers in an upright position. When mounting the speaker at a
height of over six feet, orient the OMD-5 speakers in an upside down position
so the grille is facing the floor.This guarantees even tonal balance no matter
which mounting configuration is most suitable for your room. Diagram 2.

You can also achieve excellent results in the rear position.Try not to place
the speakers directly into a corner. Leave 2 or more feet between the edge
of the cabinet and the sidewall, so the sound can reflect into the room
environment.The rear position is usually chosen when your room will not
accommodate the sidewall position due to unequal walls, a doorway, or a
large opening, etc. It is recommended that the rear center (6.1 system) or
dual rear surrounds (7.1) be placed at the same height as the other two rear
surround speakers wherever possible.

NOTE: The Mounting hardware for the OMD-5 and OMD-C1 can be found
inside the shipping carton.

1. Select the mounting position best suited for your room.

2. Place the wall-mounting bracket against the wall in the desired mounting

location and mark the center of the two holes with a pencil.This is where
you need to insert the appropriate mounting hardware to securely fasten
a load of the speaker. Hardware is not included with the speaker, as building
materials vary greatly in different countries, but the recommended screw
head size is a #8. Screw length is to be determined by the wall material.

3. If you are mounting directly to drywall, please ensure that you use the

appropriate anchors, as screws into drywall itself will not provide a secure
mount. Insert the anchors, and then hold the mounting bracket up to the
wall. Insert the screws until tight.Try to locate into wall studs wherever
possible. Diagram 3

4. Screw the included bolt into the insert in the back of the OMD-5 or

OMD-C1 speaker, located above the terminal cup. Hand tighten the bolt
all the way, and then loosen a few turns counter clockwise. Place the two
included rubber bumpers on the back of the speaker, on either side of the
speaker terminals. Diagram 4.

5. Hold the speaker upright, and insert the bolt head into the large hole. Let

the speaker slide down into place. Diagram 5.

Use the best quality speaker cables you have available.The length and type of
speaker cable used in your system can have an audible effect and allow you
to maximize the transmission of power from your amplifier to the speakers.
We recommend, if possible, that short runs of speaker cable connect the
power amplifier(s) and speakers and that high-quality long interconnect cables
be used to connect the preamplifier and power amplifier.This results in the
power amplifiers being close to the speakers, which may be practically or
cosmetically difficult. However, if the length of the speaker cables can be
reduced to a few meters, sonic advantages may be obtained.

WARNING! Turn your amplifier off before making or breaking any signal
connections!

All of the models in the OM Design Series feature high quality gold plated
binding post connectors.The OM Design series will accept a variety of
connector types including spade lugs, banana plugs, or pin type connectors.
The best connector in our opinion is the "Spade lug" as it provides more
contact area with the terminal and allows the binding post to be tightened
for a secure connection. Audiophiles and novices alike have preferences as to
which connector type they favor, speak with your Authorized Mirage retailer
as to which is the best for your Audio Video System. Rest assured, plain
speaker wire is more than acceptable, you can always upgrade your wires
and/or connectors later on. Remove the plastic red or black insert.The plastic
insert is a mandatory security measure, as dictated by many local and federal
government associations.

To Connect your speaker system: Start at one speaker, and connect one
channel at a time, starting with the front speakers. Always ensure that the
entire A/V system is powered OFF before performing any connections.The
positive and negative (red and black) sides of the speaker terminals MUST
match the positive and negative (red and black) terminals of the receiver or
amplifier. If they do not match, abnormal sound and a lack of bass response
will result. After connecting the front speakers, connect the rest of the
speakers to their appropriate channels of the receiver or amplifier.The three
connection methods and their explanations include:

1. Using your choice of speaker wire and termination method, connect the

speaker cable (minding the positive and negative polarities), to the lower
set of connectors. Ensure the terminals are tight.The gold “shorting straps”
that connect the lower and upper connections must remain in place
(OMD-15 only). Diagram 6.

2. Repeat the procedure for the second speaker.

This method involves using multiple cables and connectors, to access two sets
of terminals on the OM Design loudspeakers simultaneously.The benefit of
bi-wiring is to reduce noise, as you will have twice the thickness of cable
between the amp and speakers as the traditional method would provide. For
more details on the benefits of bi-wiring, please discuss this with your
authorized MIRAGE

retailer.

Before starting, remove the gold “shorting straps”, which connect the top and
bottom set of input terminals of the OMD-15.To remove the straps, loosen
all of the connectors and pull the straps away from the binding posts. Make
sure you put them in a safe place for future use.

Then simply connect two separate set of wires to the four binding posts.

The OM Design series can also be connected to multiple amplifiers.Two
amplifiers in the case of the OMD-15 can further enhance the performance
of the OM Design series. However, choosing quality electronics is a crucial
part in achieving the full benefit of bi-amping. Please consult your authorized
Mirage dealer for recommendations on adequate electronics. Please follow
the same steps as described in the section above. Instead of connecting two
sets of wires to one amplifier, simply connect one set of speaker wires to
each amplifier. Diagram 8.
