Precautions
• To prevent inductive phenomena causing humming or distortion, the speaker cables
should not be run together with electrical energy conductors, microphone cables, or
line-level audio lines.
• Use speaker cables that have markings to distinguish the polarity, such as insulation
or conductors of different colors.
• Before using the loudspeaker, carefully check that all the connections have been
made correctly to make sure there are no accidental short circuits that could cause
electrical sparks.
• Verify that the polarity of the connections to all of your loudspeakers is correct. When
more than one loudspeaker reproduces the same frequencies, but with opposite
polarity, there will be sound cancellations. Therefore, if any of the loudspeakers
are wired so that the +/- connection polarity is reversed with respect to the others,
incorrect reproduction will result. Most notably, the bass response will suffer. This
is especially true when loudspeakers are situated in adjacent positions where the
sound waves readily interact with each other.
