■ Speaker Selection
• The rated input power of the speakers that are going to be connected should be greater than
the maximum output power (in Watts) of the amplifier. Use of speakers having input power
ratings that are less than the output power of the amplifier will cause smoke to be emitted as
well as damage.
• The impedance of the speakers that are going to be connected should be 2
Ω
or greater (for
stereo connections), or 4
Ω
or greater (for bridged connections). When more than one set of
speakers are going to be used, calculate the combined impedance of the speakers and then
connect suitable speakers to the amplifier.
