The role of tube amplifier

Different power amplifiers bring different effects!

The signal from the audio source is sent to the amplifier

A lot has changed in the amp!

one.

Power amplifier for high and low impedance conversion

The signal going into the amplifier is weak, and the input impedance of the setting is high.

The interface behind the speaker connected to the power amplifier is loaded, and the output impedance is low.

So the power amplifier has carried out the appropriate high and low impedance conversion

two.

The signal transmitted into the power amplifier needs to be filtered

Filter out noise in the signal and make adjustments to the sound signal

This process determines the sound quality!

three.

The signal transmitted into the power amplifier is still a weak signal

signal needs to be amplified

Current amplification is performed on the basis of the signal processed by the previous stage, which is equivalent to power amplification

Make the signal have enough power to push the speaker to sound

Four.

Power amplification not only makes the speaker sound, but also has an important impact on the sound quality

The impact on the dynamic performance, balance and stability of the sound

The higher the power, the better the sound performance than the lower power amplifier!

five.

There are tubes or transistors on the power amplifier

The sound wave curve of the tube power amplifier is relatively gentle, and it is the peak of the overcharged music signal

Tube amps don't noticeably clip, just round the tip of the peak

Thereby distorting the sound signal very little.

When the transistor power amplifier changes rapidly in the sound wave, the nonlinear distortion increases rapidly

Seriously clips the signal, instead of rounding the peaks it cuts them neatly flat

As a result, the sound signal is distorted more.
