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 2Ω or greater (for stereo connections), or 4Ω 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. 8
