taps, to better adapt each speaker to the type of line (constant voltage @ 70V or
100V), the power of the amplifier, and the number of speakers in the system.
When connect the speaker to the 70/100V line, pay attention to wire colors. Please
refer to the following table when connect them to the line.

Connect Black wires to Ground terminal (-) of the 70/100V amplifier. Connect
White (full power) or Red Wires (half power) on (+) terminals of the 70/100V
amplifier according to the number of speakers used, and the amplifier power.

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.

NOTE: Total number of speakers multiplied by tap value cannot
exceed the output power (in watts) of the 70V/100V amplifier. The
