Here are some suggestions which will prove useful in
obtaining a well-balanced audio system:
Employ an amplifier with as much power (current capa-
bility 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 generally
results in cleaner. better defined bass response. And. while low
distortion. excellent phase characteristics and low noise are all
extremely important performance parameters. sufficient power
into a IOW'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 than a high power amplifier playing at loud sound
levels. This occursbecausemany amplifiers "clip" their output
very "hard" when overdriven. creating high frequency distor-
tion which can cause the voice
eventually fail. Therefore, always opt for an amplifier with high
power. Your authorized Infinity dealer can best answer your
questions and make recommendations.
• Renaissance speakers are extremely revealing and will
quickly identify sonic anomalies within the listening system.
Poor quality speaker cables on component interconnects can
add harshness, detract from spaciousness and reduce airiness
around instruments. At times. it may be advisable to connect
your CD player directly to the power amplifier, providing the
CD player has a level control.
Eliminating the preamplifier from the loop often results in
superior performance since this reduces the number of stages
through which the signal has to travel. Connecting cables
should be of the highest quality.
connected directly to the pow'er amplifier. place it close to the
power amplifier to keep the connecting cables as short as
possible.
CONNECTION USING
A STEREO AMPLIFIER
Always keep the power of your entire system "off' before mak-
ing connections to your speakers.
Connect each speaker to your amplier's output terminals
using the heaviest gauge wire you can obtain. The choice of
speaker connecting wire is extremely important. especially
when using speakers as sonically
Renaissance. 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 espe-
cially 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 speakerssound 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 what-
ever the other color may be) for negative. See figure l.

Figure 1: Some Examples Of Polarity Coding On Speaker Cables
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 speakers are out of phase, the drivers in
one channel will move in while
out. This condition invariably results in sonic problems and
must be avoided.
The gold-plated speaker terminal locking nuts which clamp
the shorting straps and speaker wire must be absolutely tight.
This will prevent distortion which can be caused by poor con-
tact between the cable and shorting straps at the speaker termi-
nals. See figure 2.
Figure 2: Renaissance Series Speaker Input Terminals
Using one length of speaker wire, connect the right speaker
to your amplifier's right channel output terminals. Be careful to
observe polarity. Connect the positive speaker terminal to the
positive amplifier terminal and the negative speaker terminal to
the negative amplifier terminal. Connect the left speaker in the
same manner. See figure 3.
