Connecting the Amplifier
K-array’s Kommander line of amplifiers featuring built-in
DSP will operate the Truffle subwoofers at their optimized
performance only with the proper preset.
Load the device preset according to the connected
loudspeaker before applying any signal to the unit.
Set the dedicated
Truffle-KTR24 / Truffle-KTR25 / Truffle-KTR26
DEVICE PRESET on the amplifier DSP
BEFORE applying any signal to the loudspeaker
Before connecting the loudspeaker cable to the amplifier:
• ensure the loudspeaker impedance matches the
amplifier channel rated loading impedance, especially
when connecting multiple loudspeakers in parallel (see
next paragraph);
• ensure that the amplifier is switched off.
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-.
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.
Use the table below to match the number of loudspeakers at
the specified impedance that can be connected to K-array’s
Kommander amplifiers.
