Abstract

As a load of the linear audio amplifiers are used in speaker. These speakers are electrodynamic systems, which when modifying the operating frequency change their parameters. Such dependence is observed in speakers, which are composed of two or more loudspeakers. This frequency dependence is an indication of the unevenness of the dynamic characteristic. This affects the operation of the amplifier, as some hybrid audio amplifiers require suppression of the input (mode „mute”). Suppression of the input signal was observed in leaps his amendment, as well as switching the mode hybrid amplifiers - Class G and Class H. At this load the amplifier load may have both capacitive and inductive.
