Amplifier advisor

In a hi-fi system is the amplifier the heart, because the incoming signals from the source devices are processed here and they are sent to the speakerforwarded. By processing is meant that the low voltages of the input signals of the amplifier into the higher currents and voltages are converted. Important for one amplifier is that a distinction is made between different types. There is the preamplifier between the actual power amplifier and the signal source. The incoming signals are brought to the same level so that they can be optimally processed by the power amplifier and then passed on to the low-impedance speakers with the right voltage. The preamp can not only be switched between the signal sources, but also heights, mids, bass and balance can be controlled or other filters can be switched on. Becomes a record playeroften used the phono preamplifier. This will then bring the level of the turntable to the level of one CD playeror the other player aligned. Depending on the output voltage and type, a distinction is made between MC and MM pickups. There are some phono preamplifiers that can handle both systems. In the meantime, however, the market is dominated by the power amplifiers, and these are devices that combine the power amp and preamp in a single package. There are also teams of pre-amp and power amp and the expensive station wagons are particularly popular with audiophiles. By the Integrated amplifierBoth tasks are taken over, because the sound source is controlled and the signals are forwarded to the loudspeakers with the correct voltage. In the current and voltage amplification different electronic components are used by the devices and so tubes, transistors or a hybrid of both. Since the 60s, there are the transistors amplifier and they could run out of expensive and wear-prone tube amplifiers rank. Many hi-fi fans swear the lovingly constructed tube amplifier, because here the sound is warmer. There are also the Headphone amplifierand they are a special case. The headphonesound better with cheaper models than the integrated amplifier, the built-in amplifiers. The expensive headphone amplifiers are especially useful when mixing and listening to studio recordings.

What must be considered in the purchase?

Not only the excellent music source is important for the good sound and not only the good speakers, but also the high quality amplifier , You can connect more audio sources, the more connections you have amplifier gives. In different areas, the amplifiers are used in home theater systems, in stereos, in cars or even in music studios. Primarily, a sound signal is always amplified by the audio amplifier. As a rule, the power in watts is specified here. Not the maximum output power is important, but the RMS performance. Generally distinguishable are the end and preamplifiers. The low input signals are picked up by the preamplifiers and for the actual amplifier they are optimally processed. The power amplifiers, however, are operated with the high input level. In front of the speakers or the recording device, they are usually the last resort. There are still the integrated amplifier and here are just combined in one device, the pre and power amplifier. Impedance and harmonic distortion are two important factors in amplifiers. The harmonic distortion factor indicates the frequencies of background noises and because background noises disturb the distortion factor should be low. The impedance, on the other hand, represents the current resistance and the higher the impedance, the less current can flow through the speaker.
