At the heart of a hi-fi system is the amplifier, because the incoming signals from the source devices are processed here and forwarded to the loudspeakers. Processing means that the low voltages from the input signals are converted by the amplifier into the higher currents and voltages. It is important for an amplifier to distinguish between different types. There is a preamplifier between the power amplifier itself and the signal source. The incoming signals are thus brought to the uniform level so that they can be optimally processed by the power amplifier and then passed on to the low-impedance loudspeakers with the correct voltage. The preamp can not only be switched between the signal sources, but also treble, mids, bass and balances can be controlled or other filters can be added. If a turntable is used, the phono preamplifier is often used. This adjusts the level of the turntable to the level of a CD player or other playback device. A distinction is made between MC and MM pickups depending on the output voltage and type. There are some phono preamplifiers that can handle both systems. In the meantime, however, the market is dominated by full amplifiers and these are devices that combine the power amplifier and the preamplifier in a single housing. There are also pre and power stage combinations and the expensive combos are especially popular with audiophiles. The integrated amplifier takes over both tasks, because the sound source is controlled and the signals are passed on to the loudspeakers with the correct voltage. For current and voltage amplification, various electronic components are used by the devices, such as tubes, transistors or a mixture of both. Transistor amplifiers have been around since the 60’s and have outstripped the expensive and wear-prone tube amplifiers. Many HiFi fans swear by the lovingly constructed tube amplifiers, because here the sound is warmer. In addition, there are also the headphone amplifiers and they are a special case. The headphones also sound better with cheap models than via the integrated amplifier, via the built-in power amplifiers. The expensive headphone amplifiers are used especially for mixing and monitoring studio recordings.

Audio & Hifi: Amplifiers Video Guide
Not only the excellent music source is important for the good sound, but also not only the good loudspeakers, but also the high-quality amplifier. The more connections there are to an amplifier, the more audio sources can be connected. The amplifiers are used in various areas, such as home cinema systems, stereo systems, cars and music studios. Primarily, a sound signal is always amplified with the audio amplifier. As a rule, the power is indicated here in watts. Not the maximum output power is important, but the RMS power. A general distinction must be made between the power amplifiers and the preamplifiers. The low input signals are picked up by the preamplifiers and optimally processed for the actual amplifier. The power amplifiers, however, are operated with the high input level. They are usually the last instance before the loudspeakers or the recording device. There are still the integrated amplifiers and here the pre- and power amplifiers are combined in one device. Impedance and distortion are two important parameters for amplifiers. The distortion factor indicates the frequencies of background noises and because background noises interfere, the distortion factor should be low. The impedance is the current resistance and the higher the impedance, the less current can flow through the speaker.
