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 4Ω be used, calculate the combined impedance of the speakers and then connect suitable speakers4Ω the 4Ω to 4Ω amplifier. 7 Sélection des haut-parleur Cleaning the unit If the front panel gets dirty, turn off the power and wipe the panel with a dry silicon cloth or soft cloth. Familiarity with installation and operation procedures will help you obtain the best performance from your new power amplifier.
