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 are 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.
