PAGING AMPLIFIER FOR A KEY TELEPHONE SYSTEM Abstract of the Disclosure The amplifier includes an audio signal input means and a first pair of integrated circuit audio power amplifiers each having an inverting input and a non-inverting input. The inverting input of one of the first pair of amplifiers is coupled to the input means and the non-inverting input of the other of the first pair of amplifiers is coupled to the input means. A first load has one terminal coupled to the output of one of the first pair of amplifiers and the other terminal coupled to the output of the other of the first pair of amplifiers. A second pair of integrated circuit audio power amplifiers each having an inverting input and a non-inverting input. The inverting input of one of the second pair of amplifiers is coupled to the input means and the non-inverting input of the other of the second pair of amplifiers is coupled to the input means. A second load has one terminal coupled to the output of one of the second pair of amplifiers and the other terminal coupled to the output of the other of the second pair of amplifiers. The first and second loads are coupled in series to provide positive and negative amplified audio output signals for the paging amplifier. - 1 -
