Guide for buyers

The number of “channels” refers to the number of speakers the amplifier has built-in. A mono amp (see more below) power 1 single speaker, or can handle 1-2 subwoofers. Similarly, 2-channel amps are designed for 2-speaker systems, 3-channel amps for 3 speakers, and 4 channel 4-speaker systems.

One method is used to classify the electrical characteristics of different types of amplifiers as a “class”, and thus amplifiers such as these are distinguished by their frequency and mode of operation. After that Amplifier Class is a term used to distinguish between different types of amplifiers.

Amplifier classes represent the amount of output signal that varies within the amplifier frequency over a single operating cycle when excited by a sinusoidal input signal. The classification of amplifiers is based on direct performance (used for high signal extension) with very low, absolute non-linear performance (where reliable signal production is less important) but more efficient, and some consistency between the two.

Amplifier classes are mainly illuminated by two basic groups. The first is the phase-controlled conduction angle signals that form the most common A, B, AB and C phases, defined by the length of their lead position over a given waveform, such that the operation of the transistor output stage lies somewhere between “ FOR complete VIEW and “for ALL”.

The second set of amplifiers is a new classification called “switching” amplifiers of D, E, F, G, S, T, etc., which use digital circuits and frequency switching (PWM) to exchange signal between “fully-ON and” ON completely ”drive output in transistors saturation and cut off.

The amplifier classes are mostly made up of those used as audio amplifiers, especially class A, B, AB, and C and to keep things simple, these are the types of amplifier classes that we will look at here in more detail.
