Why more and more professional sound engineers choose switching power amplifiers?

Power amplifier, it can be said to be the largest family of all kinds of audio equipment. Amplifiers used in stadiums, theaters, dance halls, conference halls, public places, and recordings, etc., generally have some unique requirements on their technical parameters.


With the development of technology, in the current market, the power amplifiers are mainly traditional transformer power amplifiers and switching power amplifiers. However, switching power amplifiers have gradually become the first choice for dj and audio engineers. Why? Today, let us find the reason together.


 

First, let's know what is a switching power supply?

A switching power supply is a power supply that uses modern power electronics technology to control the ratio of the time that the switching transistor is turned on and off, and maintains a stable output voltage. The switching power supply is generally controlled by a pulse width modulation (PWM) control IC. MOSFET composition. With the development and innovation of power electronics technology, switching power supply technology is constantly innovating. At present, switching power supplies are widely used in almost all electronic devices due to their small size, light weight and high efficiency. It is an indispensable power supply method for the rapid development of the electronic information industry.

Switching power amplifiers are gradually becoming the mainstream in the power amplifier market under this technology.
 

Switching power supplies VS Traditional transformer power supplies
 
  Switching power supplies Traditional transformer power supplies
Efficiency  High efficiency (up to 75% to 90%), low heat generation, low power consumption.   Low efficiency (only 30% to 50%), easy to heat, high power consumption.
Weight lighter in weight and smaller in size. Heavy in weight and inconvenient to use.

Compared with conventional power amplifiers, switching power supplies have the advantages of small size and light weight.

1.The switching power amplifier has high efficiency (up to 75% to 90%), low heat generation and low power consumption. Almost all energy is reserved for audio output.

2.Switching power amplifiers are lighter in weight and smaller in size due to the use of compact circuits and smaller heat sinks.

3.The switching power supply converts alternating current into direct current through transistor switches and other components. The switching power amplifier achieves amplification of the audio signal by switching the transistor switch at a high frequency.


 
Traditional transformer power supplies:
1. Heavy in weight and inconvenient to use.
2. Low efficiency (only 30% to 50%).
3. Moreover, in order to pursue profits, manufacturers in the market are all using inferior selenium steel sheets or fakes, which leads to overheating of the transformer and lower efficiency.



With the development of technology, switching power supply amplifiers have gradually become a trend, and the modern switching power amplifier technology is more mature, no matter in terms of sound quality, power conversion rate, cost, volume, process complexity, etc., it is better than traditional transformer power amplifiers. This is also the main reason why switching power amplifiers are increasingly attracting dj and sound engineers.
