5.2. Speaker Connection
GLOBE-560XW is equipped with a built-in line transformer and a power selector
to better adapt each speaker to the type of line (constant voltage @ 70V or 100V,
or low-impedance), the power of the amplifier, and the number of speakers in the
system. The power selector is located on rear side of the speakers.
Please check the following table and adjust the knob accordingly.

Connect Black wires to Ground terminal (-) of the 70/100V or low-impedance
amplifier. Connect the other wire to (+) terminals of the 70/100V or low-imped
-
ance amplifier.

In case of parallel speaker connection, please make sure that there is not in-
verted polarity (+ connected to -). If the polarity of the speakers is reversed, the
sound will be unnatural and will play without bass.
6. UNDER-POWERING VS OVER-POWERING
Most speaker damages are caused by amplifiers with too little power (wattage).
Overdriven amplifiers clip output waveforms and send distortion to the speakers.
Clipping is usually audible; it may vary from a harsh sound to a fuzzy or unclear
sound.
If you hear this condition at loud volume levels, turn down the amplifier volume
until the distortion is no longer present. Damages caused by operating the speak-
ers at distorted volume levels are no covered by warranty.
