Amplifiers and power amplifiers

The name gives it away: amplifiers magnify the incoming sound signals in order to reproduce them louder. This is not just about full-sounding concerts. In the studio, too, it is important to first bring all the different inputs up to a common line level. In the home theater, too, the sound experience is sensitively disturbed by too loud voices or flat basses.

Separate power amplifier or built-in amplifier?

In the LTT online store you will find a fine selection of both external amplifiers and universal devices, in which the power amplifier is built into the housing as a component.

Internal amplifier

The built-in amplifier keeps the entire setup slim and provides sufficient power for home use. The trend is definitely towards compact integrated amplifiers, which is why separate power amplifiers are becoming increasingly rare.

Separate amplifier

But external amplifiers will probably never completely disappear. In the professional field and among audiophiles, only the classic circuit is the right one. There are several reasons for this:

Avoiding interfering signals: Even though technology is improving all the time, it is unfortunately still not possible to completely prevent undesirable influences on the sensitive preamplifier in universal devices. Spatially separating the power amplifier reduces possible interference signals that could distort, wash out or overdub the frequencies.

Maintaining tradition: Audio enthusiasts swear by the tried-and-true switching series with separate preamplifier and power amplifier: It was the standard for a long time. Besides, today's music has the reputation again and again of having been produced with too little sense of depth. Those who value the very fine nuances can get the most out of a piece of music with an external power amplifier.

Unlimited customization: Only separate power amplifiers offer maximum flexibility in bringing out the very best sound. If you really want to tune your set-up perfectly, a separate amplifier is essential.

Full power at the concert: Let's not forget the big music stages! Here, good sound is the main player. The PA system must deliver the best possible sound quality at full power. You won't get far without a professional multi-channel amplifier. For live concerts, it's also essential to work with high-quality preamps, such as microphone preamps.

The full listening experience in the home theater: Big screen, flat sound? If movies are to be an audio-visual adventure for you, you need a good audio system. For really good surround sound, you need different speakers - several for the frontal sound, at least two for the rear and a passive or active subwoofer so that the gut feeling is also right. You control all elements precisely with an external amplifier.

How digital is your digital amplifier?

Depending on the switching concept, amplifiers are divided into Class A, Class B, Class A/B and Class D amplifiers. The latter are the increasingly popular digital amplifiers. Contrary to popular belief, however, these amplifiers are not designed to process only digital inputs, or to provide purely digital power amplification. Instead, the input signal - whether analog or digital - is converted into pulses before being amplified in the output stage. Here, the output stage does not know any intermediate stages, as in the linear operation of Class A, B and A/B amplifiers, but works only with a fixed number of values. It only knows the states on and off. As a result, losses are much lower in digital power amplifiers. These power amplifiers are therefore particularly high-performance and have only low power losses. At the same time, they are small and lightweight as well as network and Bluetooth compatible. For many, a digital amplifier is the optimal choice, which is why this market is growing more and more.
