– Owner’s Manual ◆3
INTRODUCTION
You have invested in one of the finest audio/video speakers available. Your
Infinity Omega speaker employs new technology in driver, crossover and
cabinet construction, which places it at the forefront of current speaker design.
As with any high-quality product, special care must be taken to install and
operate your new speaker. It is for this reason we suggest you read this manual
carefully from cover to cover prior to installation.
UNPACKING
Upon opening the carton, inspect the speaker carefully for any sign of transit
damage. If there is damage, immediately call your dealer or the trucking firm
that made the delivery. Do not delay in reporting the damage because the
longer you wait, the more difficult it will become to file a claim. We suggest
that you fold the carton flat and store it for future use.

ASSOCIATED COMPONENTS
Your Infinity Omega speaker is an extraordinary, highly musical system. Like
all loudspeakers, it will reproduce distortion as well as music. For this reason,
the choice of associated audio components is critical and should be made with
care. If you are replacing existing speakers with an Infinity Omega System,
there should be an audible improvement in sonic quality, assuming your other
components are at least on a par with the Omega speaker in terms of low distortion, phase linearity, frequency response and so on.
If no improvement is heard, or if the sound deteriorates, it is possible that one
(or more) of your existing components is of a lower standard than your new
Infinity speaker. When a speaker system is exceptionally revealing, musical
colorations and other forms of distortion become more noticeable because
these aberrations are no longer masked by the speaker. Here are some suggestions that will prove useful in obtaining a well-balanced audio system:
• Employ an amplifier with as much power (current capability into an impedance of 4 ohms) as possible. Since quality speakers work best when driven by
high current, the choice of an amplifier with a strong, adequate power supply
and a heavy-duty and rugged output stage generally results in cleaner, betterdefined bass response. And, while low distortion, excellent phase characteristics and low noise are all extremely important performance parameters, sufficient power into a low impedance load (4 ohms or lower) on a continuous
basis is equally important.
• Another consideration is that a lower power amplifier operating at its maximum power output can damage a speaker more quickly that a high power
amplifier playing at loud sound levels. This occurs because many amplifiers
“clip” their output very “hard” when overdriven, creating high-frequency distortion, which can cause the voice coil of a tweeter to heat and eventually fail.
Always choose an amplifier with high power. Your authorized Infinity dealer
can best answer your questions and make recommendations.
• The Omega speaker is extremely revealing and will quickly identify sonic
anomalies within the listening system. Poor-quality speaker cables and component interconnects can add harshness, detract from spaciousness and reduce
airiness surrounding instruments and voice.
INSTALLATION OF SPIKES
Please note that the speakers stand on spiked feet, which come with plastic
caps installed to prevent injury to you and your belongings. The loudspeakers
will perform best when the spikes make direct contact with the floor. If you
wish to protect hardwood or other solid floors, leave the plastic caps in place.
To level the speaker and to provide firm support at each corner on uneven
floors, you can adjust the height of each foot by screwing it in or out of the
bottom of the speaker. When installing the spikes, be very careful not to allow their
sharp points to injure you or anyone helping you.

CONNECTIONS USING A STEREO AMPLIFIER
Always turn off the power of your entire system before making connections to
your speaker. Connect each speaker to your amplifier’s output terminals using
the best wire you can obtain. The choice of speaker connecting wire is
extremely important, especially when using speakers as sonically revealing as
Infinity Omega. If inferior wire is used, sonic quality will suffer and the degradation of sound will be readily audible. For best results, do not use wire that is
thinner than 16 gauge. NOTE: the lower the gauge number (16, 14, 12, etc.),
the heavier the wire. Although gauge alone does not reveal the ultimate sonic
quality of wire, it represents a good starting point, especially if you are not
using a name-brand speaker connecting cable. Consult your dealer if you are
not certain which type of wire will make your Infinity speaker sound best.
When using regular lamp cord, look for ridges or different colored insulation
to differentiate polarity. If there is a ridge on the outer insulation, use the ridge
for positive (+) and the wire without the ridge for negative (-). If the insulation
wrapped around one wire is red, use it for positive. Use white (or whatever the
other color may be) for negative. (See figure 1.)
It is important to connect your speakers in phase (which means that all individual drivers are moving in and out in the same direction and at the same
time) in order to obtain the best localization of instruments and voice as well
as the deepest, most natural bass. If a speaker is out of phase, the drivers in
one channel will move in while the other channel will move out. This condition invariably results in sonic problems and must be avoided.
