All unpowered HOT SPOTS have a 16 ohm impedance, and like
most professional-type speakers have two jacks which are wired in
parallel (meaning the signal can travel into one jack and out of the
other).Think of each speaker as a "load" added to the amplifier. The
greater the number of speakers, the heavier the load. Adding too
many speakers can overload the amplifier, causing it to overheat
and distort. If the amplifier begins to distort, or if it becomes hot to
the touch, disconnect any extra speakers. One easy way to
determine the load on the amplifier is to use Ohm's law, which
states: "The total impedance of N speakers in parallel is equal to
the reciprocal of the sum of the reciprocals. In equation form:
