Connecting
Lyzard-KZ14 is already pre-wired with 5 m (16.4 ft) of ultra-
thin speaker cable to be directly connected to any K-array
power amplifier.
K-array’s Kommander line of amplifiers featuring built-in DSP
will operate the Lyzard-KZ14 at its optimized performance only
with the proper device preset: insure to load the Lyzard-KZ14
device preset before applying any signal to the loudspeaker.

Loudspeakers in parallel
By connecting the loudspeakers in parallel it is possible to
drive many loudspeakers with the same audio signal by
means of a single amplifier output channel.
The parallel connection lowers the total load impedance:
caution must be taken to maintain the load impedance of
the paralleled loudspeakers above the amplifier’s minimum
loading impedance.
Leveraging on the Lyzard-KZ14 impedance, up to 4
loudspeakers can be connected in parallel to the same
amplifier output channel.

BEFORE applying any signal to the loudspeaker
The Lyzard-KZ14 ultra-thin speaker cable
should not be cut, jointed or soldered .
Instead of altering the wiring, replace the cable.
Before connecting the loudspeaker cable to the amplifier:
• insure the amplifier’s minimum loading impedance
is matched, especially when connecting multiple
loudspeakers in parallel (see next paragraph);
• insure that the amplifier is switched off.
In case of cable replacement, for a cable run of up to 5 m
(16.4 ft) use wire gauge of 0,5 mm
2
(24 AWG) at least.
For longer cable runs a wider gauge is recommended.
In order to screw the terminals of the Lyzard-KZ14, use 2 mm
(5/64 in) standard (flat-blade) screwdriver.
Caution must be taken when connecting the loudspeaker
cable to the amplifier’s terminal to match the signal polarity:

HOT red wire
–
COLD black/blue wire
When connecting the wires to a SpeakOn NL4 connector,
screw the HOT+ wire to the terminal 1+ or 2+ and the
COLD– wire to the terminal 1- or 2-.
