When an output becomes a upper, the signal supplied to an output transistor by the monitor circuitry is restricted, and the output of amplifier short-circuits or it prevents a corruption of an output transistor. This circuitry will become a high impedance if an Output voltage becomes more than a rate, but this does not have influence on an output. In order to prevent an output transistor carrying out an overload, the output signal is always supervised by the monitor circuitry of the mac patent. Transformer eliminated that component and this transformer has prevented theД¬orruption of the speaker, when it has a role which protects a speaker in theД¬ase of a malfunction of amplifier and a direct current component mixes in an Maximum output is obtained to all the signalling frequencies. Output-terminal of every impedance, even if it uses which output-terminal, the Since this transformer is designed match the The output signal of MC2200 passes an output transformer and Nature Emitter-Follower join, a stability is good, and distortion's hasДecreased and this circuitry has realized B class operation without crossoverДistortion by adoption of a still more original output bias circuitry. It consists of six reliable complimentary power transistors. The para-push scheme of a single ended is used for an output stage, and A power transistor is ABД¬lass operation and, as for the bias current, the safeness is maintained by the To the transition of a temperature, this circuitry isДesigned so that a moderate bias may always start.

The circuitry of the following stage is a voltage amplifying circuit of aД¬lass-A operation, and a driver circuitry and an output circuit adopt aД¬omplimentary scheme, carry out the operation near a Class-A, and are reducing Input signal and a feedback signal are supplied to this differential amplifier. It hits power-meter the non-carrying model of MC2205.Дistortion is removed by using the monolithic transistor differentialДЄmplifier with few noises for the input side of a power amplifier circuitry. Time power amplifier which carries an original
