CONNECTIONS
Make sure all equipment is turned off before making connections.
To connect the loudspeakers to the receiver or amplifier, use two conductor insulated
wire. Your Infinity dealer can recommend suitable cables. We recommend 1.3 mm
diameter (16 AWG) as a minimum size. If your speakers are more than 10 m (30 feet)
from your receiver or amplifier, use larger diameter wire. Interconnects are an
important component in an audio system. You may wish to audition and compare the
performance of some of the specialty audio interconnects and speaker cable available
from your dealer.
For each channel, the red terminal on the loudspeaker should be connected to the
red or (+) loudspeaker connection terminal on the amplifier (or receiver), and the
black terminal on the loudspeaker should be connected to the black or (–) terminal on
the amplifier. Connecting the loudspeakers in this manner ensures that they will work
in phase; that is, work together rather than in opposition. Connecting the loud-
speakers out of phase will not damage them, but will result in less bass and poor
imaging. Most two-conductor wire is color-coded or has a ridge on one of its
insulating jackets, so that you can easily identify which wire is connected to which
terminal. When connecting more than one pair of loudspeakers to an amplifier or
receiver, consult your dealer or amplifier manufacturer to ensure that the resulting load
can be handled safely.

high frequency transducer. Further excessive boost by the amplifier or receiver's tone
controls can aggravate the situation. Our advice is always to use an amplifier or
receiver that will make your KAPPA speakers play reasonably loud, and at the same
time sound clean and undistorted.

BI-WIRING
®
All KAPPA speakers can be bi-wired. Before bi-
+
wiring, ALWAYS remove the metal bars between
the high and low inputs.

Bi-wiring will improve resolution and dynamics.
For even greater improvement, you may use two
amplifiers (bi-amping).
DANGER: LOW POWER
Generally, loudspeakers can withstand a great
deal of power, as long as the signal is undistorted.
You can safely use a power amplifier with a power

rating greater than a speaker system's re-
commended power, as long as you don't over-
drive the amplifier. When amplifiers are over-
driven, they "clip" the signal, creating distortion
that appears as high energy high frequency
signals. These distortion products are directed to
the high frequency transducer by the crossover

network, thereby creating a dangerous condition
